The YELLOW  dots indicate some of the submarine features worth zooming in close to see the submarine ridges, trenches and fractures that form the edges of the tectonic plates.
When you zoom in real close you may see two lines, one for each neighboring plate. Google Map evidently won't save the map with all the lines covering each other.I drew them overlapping so that you can turn them on and off independently of each other in Google Earth. But when I reopen the map some of the lines moved.

African Plate
Wikipedia (http://en.wikipedia.org/wiki/African_Plate)
The African Plate is a tectonic plate which includes the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges.
The African Plate's speed is estimated at around 2.15 cm (0.85 in) per year. It has been moving over the past 100 million years or so in a general northeast direction. This is drawing it closer to the Eurasian Plate, causing subduction where oceanic crust is converging with continental crust (e.g. portions of the central and eastern Mediterranean).

South American Plate
Wikipedia (http://en.wikipedia.org/wiki/South_American_Plate)
The South American Plate is a tectonic plate which includes the continent of South America and also a sizeable region of the Atlantic Ocean seabed extending eastward to the Mid-Atlantic Ridge.
The South American Plate is in motion, moving westward away from the Mid-Atlantic Ridge. The eastward-moving and more dense Nazca Plate is subducting under the western edge of the South American Plate along the Pacific coast of the continent at a rate of 77 mm per year.[1] This collision of plates is responsible for lifting the massive Andes Mountains and causing the volcanoes which are strewn throughout them.

Indian Plate
Wikipedia (http://en.wikipedia.org/wiki/Indian_Plate)
The India Plate or Indian Plate is a tectonic plate that was originally a part of the ancient continent of Gondwana from which it split off, eventually becoming a major plate. About 55 to 50 million years ago it fused with the adjacent Australian Plate. It is today part of the major Indo-Australian Plate, and includes most of South Asia – i.e., the Indian subcontinent – and a portion of the basin under the Indian Ocean, including parts of South China and Eastern Indonesia,[1][2][3] and extending up to but not including Ladakh, Kohistan and Balochistan.[4][5][6]
The Indian Plate is currently moving north-east at 5 centimetres (2.0 in) per year, while the Eurasian Plate is moving north at only 2 centimetres (0.79 in) per year. This is causing the Eurasian Plate to deform, and the India Plate to compress at a rate of 4 millimetres (0.16 in) per year.

Indo-Australian Plate
Wikipedia (http://en.wikipedia.org/wiki/Australian_Plate)
The Indo-Australian Plate is a major tectonic plate that includes the continent of Australia and surrounding ocean, and extends northwest to include the Indian subcontinent and adjacent waters. It was formed by the fusion of Indian and Australian plates 43 million years ago.[1] Recent studies, and seismic events such as the 2012 Indian Ocean earthquake, suggest that the Indo-Australian Plate may be in the process of breaking up into two separate plates due primarily to stresses induced by the collision of the Indo-Australian Plate with Eurasia along the Himalayas.[2] The eastern part (Australia) is moving northward at the rate of 5.6 cm per year while the western part (India) is moving only at the rate of 3.7 cm per year due to impediment by Himalayas. This differential movement is resulting in the compression of the plate near its center at Sumatra and a potential division into Indian and Australian Plates.[3][4][5] The two protoplates or subplates are generally referred to as the Indian Plate and the Australian Plate.

Arabian Plate
Wikipedia (http://en.wikipedia.org/wiki/Arabian_Plate)
The Arabian Plate is one of three tectonic plates (the African, Arabian and Indian crustal plates) which have been moving northward over millions of years and colliding with the Eurasian Plate. This is resulting in a mingling of plate pieces and mountain ranges extending in the west from the Pyrenees, crossing southern Europe and to Iran forming the Alborz and Zagros Mountains, to the Himalayas and ranges of southeast Asia. [1]

Caribbean Plate
Wikipedia (http://en.wikipedia.org/wiki/Caribbean_Plate)
The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America.
Roughly 3.2 million square kilometers (1.2 million square miles) in area, the Caribbean Plate borders the North American Plate, the South American Plate, the Nazca Plate and the Cocos Plate. These borders are regions of intense seismic activity, including frequent earthquakes, occasional tsunamis,[1] and volcanic eruptions.

Caribbean Plate shape

North American Plate
Wikipedia (http://en.wikipedia.org/wiki/North_American_Plate)
The North American Plate is a tectonic plate covering most of North America, Greenland, Cuba, Bahamas, and parts of Iceland and the Azores. It extends eastward to the Mid-Atlantic Ridge and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. The interior of the main continental landmass includes an extensive granitic core called a craton. Along most of the edges of this craton are fragments of crustal material called terranes, accreted to the craton by tectonic actions over the long span of geologic time. It is believed that much of North America west of the Rockies is composed of such terranes.
For the most part, the North American Plate moves in roughly a southwest direction away from the Mid-Atlantic Ridge.
The motion of the plate cannot be driven by subduction as no part of the North American Plate is being subducted, except for a small section comprising part of the Puerto Rico Trench; thus other mechanisms continue to be investigated.
One recent study suggests that a mantle convective current is propelling the plate.[6]

Eurasian Plate
Wikipedia (http://en.wikipedia.org/wiki/Eurasian_Plate)
The Eurasian Plate is a tectonic plate which includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia), with the notable exceptions of the Indian subcontinent, the Arabian subcontinent, and the area east of the Chersky Range in East Siberia. It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge.

Scotia Plate
Wikipedia (http://en.wikipedia.org/wiki/Scotia_Plate)
The Scotia Plate, named after the sea which overlies it, is a tectonic plate on the edge of the South Atlantic and Southern Ocean. Thought to have formed during the early Eocene with the opening of the Drake Passage, it is a minor plate whose movement is largely controlled by the two major plates that surround it; the South American plate and Antarctic plate. Having formed as oceanic crust, it is almost completely submerged with only the small exception of the South Georgia Islands on its north-eastern edge and the southern tip of South America.[1]

Scotia Plate shape

Nazca Plate
Wikipedia (http://en.wikipedia.org/wiki/Nazca_Plate)
The Nazca Plate, named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction, along the Peru-Chile Trench, of the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise and the Chile Rise respectively. The movement of the Nazca Plate over several hotspots has created some volcanic islands as well as east-west running seamount chains that subduct under South America. Nazca is a relatively young plate both in terms of the age of its rocks and its existence as an independent plate having been formed from the break-up of the Farallon Plate about 23 million years ago. The oldest rocks of the plate are about 50 million years old.[1]

Cocos Plate
Wikipedia (http://en.wikipedia.org/wiki/Cocos_Plate)
The Cocos Plate is an oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America, named for Cocos Island, which rides upon it.
The devastating 1985 Mexico City earthquake was a result of the subduction of the Cocos Plate beneath the North American Plate. The also devastating 2001 El Salvador earthquakes were generated in the subduction of this plate on the Caribbean Plate.

Juan de Fuca Plate
Wikipedia (http://en.wikipedia.org/wiki/Juan_de_Fuca_Plate)
The Juan de Fuca Plate is a tectonic plate generated from the Juan de Fuca Ridge and is subducting under the northerly portion of the western side of the North American Plate at the Cascadia subduction zone. It is named after the explorer of the same name.
One of the smallest of Earth's tectonic plates, the Juan de Fuca Plate is a remnant part of the once-vast Farallon Plate, which is now largely subducted underneath the North American Plate.

Philippine Sea Plate (Filipino Plate)
Wikipedia (http://en.wikipedia.org/wiki/Filipino_Plate)
The Philippine Sea Plate or Philippine Plate is a tectonic plate comprising oceanic lithosphere that lies beneath the Philippine Sea, to the east of the Philippines. Most segments of the Philippines, including northern Luzon, are part of the Philippine Mobile Belt, which is geologically and tectonically separate from the Philippine Sea Plate.

Pacific Plate
Wikipedia (http://en.wikipedia.org/wiki/Pacific_Plate)
The Pacific Plate has the distinction of showing one of the largest areal sections of the oldest members of seabed geology being entrenched into eastern Asian oceanic trenches. A geologic map of the Pacific Ocean seabed shows not only the geologic sequences, and associated Ring of Fire zones on the ocean's perimeters, but the various ages of the seafloor in a stairstep fashion, youngest to oldest, the oldest being consumed into the Asian oceanic trenches. The oldest member disappearing by way of the Plate Tectonics cycle is early-Cretaceous (145 to 137 million years ago).[4]

Pacific Plate shape

Antarctic Plate
Wikipedia (http://en.wikipedia.org/wiki/Antarctic_Plate)
The Antarctic Plate is a tectonic plate containing the continent of Antarctica and extending outward under the surrounding oceans. The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems. The adjoining plates are the Nazca Plate, the South American Plate, the African Plate, the Indo-Australian Plate, the Pacific Plate, and, across a transform boundary, the Scotia Plate.
The Antarctic plate is roughly 60,900,000 square kilometers.[1] It is the fifth biggest plate in the world.
The Antarctic plate movement is estimated at least 1 centimeter/per year towards the Atlantic Ocean.[citation needed]

1700 Cascadia undersea earthquake and tsunami ~9.0
Wikipedia (http://en.wikipedia.org/wiki/1700_Cascadia_earthquake)
The 1700 Cascadia earthquake was a magnitude 8.7 to 9.2 megathrust earthquake that occurred in the Cascadia subduction zoneon January 26, 1700.[1] The earthquake involved the Juan de Fuca Plate underlying the Pacific Ocean, from mid-Vancouver Island inBritish Columbia, Canada, south along the Pacific Northwest coast as far as northern California, USA. The length of the fault rupture was about 1,000 kilometers (620 miles) with an average slip of 20 meters (22 yards).
The earthquake caused a tsunami that struck the coast of Japan,[2] and may also be linked to the Bonneville Slide.[3]

1896 Meiji-Sanriku undersea earthquake - 8.5
Wikipedia (http://en.wikipedia.org/wiki/1896_Meiji-Sanriku_earthquake)
The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history.[2] The 8.5 magnitudeearthquake occurred at 19:32 (local time) on June 15, 1896, approximately 166 kilometres (103 mi) off the coast of Iwate Prefecture,Honshu. It resulted in two tsunamis which destroyed about 9,000 homes and caused at least 22,000 deaths.[3] The waves reached a record height of 38.2 metres (125 ft); more than a meter shorter than those created after the 2011 Tōhoku earthquake which triggered the 2011 Japanese nuclear accidents.[4]
Seismologists have discovered the tsunamis' magnitude (Mt = 8.2)[5] was much greater than expected for the estimated seismic magnitude. This earthquake is now regarded as being part of a distinct class of seismic events, the tsunami earthquake.[6]

1960 Valdivia land-based earthquake and tsunami - 9.3
Wikipedia (http://en.wikipedia.org/wiki/1960_Valdivia_earthquake)
The 1960 Valdivia earthquake or Great Chilean Earthquake (Spanish: Terremoto de Valdivia/Gran terremoto de Chile) of Sunday, 22 May 1960 was the most powerful earthquake ever recorded, rating 9.5 on the moment magnitude scale. It occurred in the afternoon (19:11 GMT, 15:11 local time), and the resulting tsunami affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands.

huffingtonpost
ACAPULCO, Mexico (AP) — A powerful magnitude-7.2 earthquake shook central and southern Mexico on Friday, sending panicked people into the streets. Some walls cracked and fell, but there were no reports of major damage or casualties.
The USGS initially calculated the quake's magnitude at 7.5, but later downgraded it to 7.2. It said the quake was centered 22 miles (36 kilometers) northwest of the town of Tecpan de Galeana, and was 15 miles (24 kilometers) deep.

4/19/2014 Solomon Sea Earthquake
earthquake.usgs.gov
The M 7.5 April 19, 2014 earthquake southwest of Panguna, Papua New Guinea, occurred as the result of thrust faulting on or near the subduction zone interface between the subducting Australia plate and overriding Pacific plate. At the location of the earthquake, the Australia plate moves towards the east-northeast at a velocity of 102 mm/yr with respect to the Pacific, and begins its subduction into the mantle beneath Bougainville Island at the New Britain Trench south of the earthquake. The moment tensor and depth of the event are consistent with thrust-type motion on the interface between these two plates. Note that at the location of the earthquake, some researchers divide the edge of the Australia plate into several microplates that take up the overall convergence between Australia and the Pacific. Here the Solomon Sea plate moves slightly faster and more northeasterly with respect to the Pacific plate than does Australia due to sea-floor spreading in the Woodlark Basin several hundred kilometers to the south of the April 19 earthquake.

8/20/2014 - Bárðarbunga volcano Iceland about to erupt
bbc.com/news (http://www.bbc.com/news/world-europe-28870969)
Iceland's authorities have evacuated an area close to the country's Bardarbunga volcano over fears it could erupt.
The area, which is more than 300km (190 miles) from the capital Reykjavik, has no permanent residents but sits within a national park popular with tourists.
The move came as geologists said about 300 earthquakes had been detected in the area since midnight on Tuesday.
Iceland's Eyjafjallajokull volcano erupted in 2010, producing an ash cloud that severely disrupted air travel.
The national civil protection agency said the decision to evacuate more than 300 people close to Bardarbunga was a "precautionary" safety measure.

With the support of the National Science Foundation, scientists are carrying out especially detailed studies at a so-called "bulls-eye" site. Many hydrothermal vents have been found in this 3.7km-long section of mid-ocean ridge. Moving out from the bulls-eye, there are various geologic features of interest, such as:
- Areas where the axis of the mid-ocean ridge (the narrow rift where most volcanic eruptions and hydrothermal activity occurs) shifts sideways by tens or hundreds of metres.
- Bodies of magma within the crust and mantle.

American-Antarctic Ridge (AAR)
Wikipedia (http://en.wikipedia.org/wiki/American-Antarctic_Ridge)
The American–Antarctic Ridge (AAR) is a tectonic spreading center between the South American Plate and the Antarctic Plate. It runs along the seafloor from the Bouvet Triple Junction in the South Atlantic Ocean southwestward to a major transform fault boundary east of the South Sandwich Islands.

Central Indian Ridge
Wikipedia (http://en.wikipedia.org/wiki/Central_Indian_Ridge)
The Central Indian Ridge (CIR) is a divergent tectonic plate boundary between the African Plate and the Indo-Australian Plate, traversing the western regions of the Indian Ocean. The northern section of the CIR is also called the Carlsberg Ridge.
The CIR extends northward from a triple point junction near the island of Rodrigues (the Rodrigues Triple Point) to a junction with the Owen Fracture Zone.

Mid-Atlantic Ridge
Wikipedia (http://en.wikipedia.org/wiki/Mid-Atlantic_Ridge)
The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of theAtlantic Ocean, and part of the longest mountain range in the world. It separates the Eurasian Plate and North American Plate in the North Atlantic, and the African Plate from the South American Plate in the South Atlantic. The Ridge extends from a junction with the Gakkel Ridge(Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level. The section of the ridge which includes the island of Iceland is also known as the Reykjanes Ridge. The average spreading rate for the ridge is about 2.5 cm per year.[1]

Southeast Indian Ridge
Wikipedia (http://en.wikipedia.org/wiki/Southeast_Indian_Ridge)
The Southeast Indian Ridge (SEIR) is a divergent tectonic plate boundary located along the seafloor of the southern Indian Ocean. It separates the Indo-Australian Plate to the north from the Antarctic Plate to the south. [1]
The SEIR extends from the Rodrigues Triple Point in the southern Indian Ocean, through the Southern Ocean south of the Australian continent, and on to the Macquarie Triple Junction in the southwest Pacific Ocean. The islands of Saint-Paul and Amsterdam are the above-water points of the Southeast Indian Ridge.

Southwest Indian Ridge
Wikipedia (http://en.wikipedia.org/wiki/Southwest_Indian_Ridge)
The Southwest Indian Ridge (SWIR) is a divergent tectonic plate boundary located along the floor of the southwest Indian Ocean. It separates the African Plate to the north from the Antarctic Plate to the south.
The SWIR extends between the Rodrigues Triple Point in the southern Indian Ocean to the Bouvet Triple Junction in the south Atlantic.

Aleutian Trench
Wikipedia (http://en.wikipedia.org/wiki/Aleutian_Trench)
The Aleutian Trench (or Aleutian Trough)[1] is an oceanic trench along a convergent plate boundary which runs along the southern coastline of Alaska and the Aleutian islands. The trench extends for 3,400 km from a triple junction in the west with the Ulakhan Fault and the northern end of the Kuril-Kamchatka Trench, to a junction with the northern end of the Queen Charlotte Fault system in the east. It is classified as a "marginal trench" in the east as it runs along the margin of the continent. The subduction along the trench gives rise to the Aleutian arc, a volcanic island arc, where it runs through the open sea west of the Alaska Peninsula. As a convergent plate boundary, the trench forms part of the boundary between two tectonic plates. Here, the Pacific Plate is being subducted under the North American Plate at a dip angle of nearly 45 degrees. The rate of closure is ~3in. (8 cm) per year.[2]

Cayman Trough
Wikipedia (http://en.wikipedia.org/wiki/Cayman_Trench)
The Cayman Trough, (also known as the Cayman Trench, Bartlett Deep and Bartlett Trough) is a complex transform fault zonepull apart basin which contains a small spreading ridge on the floor of the western Caribbean Sea between Jamaica and the Cayman Islands.[1] It is the deepest point in the Caribbean Sea and forms part of the tectonic boundary between the North American Plate and the Caribbean Plate. It extends from the Windward Passage, going south of the Sierra Maestra of Cuba toward Guatemala. The transform continues onshore as the Motagua Fault, which cuts across Guatemala and extends offshore under the Pacific Ocean, where it intersects the Middle America Trench subduction zone.

Hikurangi Trench
Wikipedia (http://en.wikipedia.org/wiki/Hikurangi_Trench)
The Hikurangi Trench (also called the Hikurangi Trough) is a linear deep in the Pacific Ocean off the east coast of the North Island of New Zealand, lying between the southern end of the Cook Strait and the Chatham Rise. Though much shallower, it is the southward continuation of the Kermadec Trench and forms part of the Kermadec-Tonga Subduction Zone. It represents the part of the subduction zone where the thick oceanic Hikurangi Plateau is subducting beneath continental crust of the Indo-Australian Plate. By contrast, the Kermadec and Tonga Trenchesrepresent the parts of the subduction zone where oceanic crust of the Pacific Plate is subducting beneath oceanic crust of the Indo-Australian Plate.

Kermadec Trench
Wikipedia (http://en.wikipedia.org/wiki/Kermadec_Trench)
The Kermadec Trench is one of Earth's deepest oceanic trenches, reaching a depth of 10,047 metres (32,963 ft). Formed by the subduction of the Pacific Plate under the Indo-Australian Plate, it runs over a thousand kilometres parallel with and to the east of the Kermadec Ridge and island arc, from near the northeastern tip of New Zealand's North Island to the trench's junction with the Louisville seamount chain northeast of Monowai Seamount. The Tonga Trench marks the continuation of subduction beyond this point. Subduction south of the Kermadec Trench is marked by the shallower Hikurangi Trench.
The Kermadec Trench is noted for its very abrupt slope.

Mariana Trench
Wikipedia (http://en.wikipedia.org/wiki/Mariana_Trench)
The Mariana Trench or Marianas Trench[1] is the deepest part of the world's oceans. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres (1,580 mi) long but has an average width of only 69 kilometres (43 mi). It reaches a maximum-known depth of 10.911 km (10,911 ± 40 m) or 6.831 mi (36,069 ± 131 ft) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end,[2] although some unrepeated measurements place the deepest portion at 11.03 kilometres (6.85 mi).[3]

Puerto Rico Trench
Wikipedia (http://en.wikipedia.org/wiki/Puerto_Rico_Trench)
The Puerto Rico Trench is an oceanic trench located on the boundary between the Caribbean Sea and the Atlantic Ocean. The trench is associated with a complex transition between the Lesser Antilles subduction zone to the south and the majortransform fault zone or plate boundary, which extends west between Cuba and Hispaniola through the Cayman Trench to the coast of Central America. Scientific studies have concluded that an earthquake occurring along this fault zone could generate a significant tsunami.[1]
The island of Puerto Rico lies immediately to the south of the fault zone and the trench. The trench is 800 kilometres (497 mi) long and has a maximum depth of 8,648 metres (28,373 ft) or 5.373 miles at Milwaukee Deep, which is the deepest point in the Atlantic Ocean and the deepest point not in the Pacific Ocean. It suffered a tsunami soon after the earthquake of 1918.

Romanche Trench
Wikipedia (http://en.wikipedia.org/wiki/Romanche_Trench)
The Romanche Trench, also called the Romanche Furrow or Romanche Gap, is the third deepest of the major trenches of theAtlantic Ocean, after the Puerto Rico Trench and the South Sandwich Trench. It bisects the Mid-Atlantic Ridge just north of theequator at the narrowest part of the Atlantic between Brazil and West Africa, extending from 2°N to 2°S and from 16°W to 20°W. The trench has been formed by the actions of the Romanche Fracture Zone, a portion of which is an active transform boundaryoffsetting sections of the Mid-Atlantic Ridge.
It is situated between the Sierra Leone Basin to the north/northeast, the South Atlantic Basin to the east/southeast, the Northern Brazilian Basin to the south/southwest, and North Atlantic Ridge to the west/northwest. Geologically, it is at the seam of the South American Plate to the West and the African Plate to the East. The trench has a depth of 7,760 m, is 300 km long and has an average width of 19 km and allows for a major circulation of deep ocean basin water from the west Atlantic to the east Atlantic basins. Deep water flow through the trench is from west to east with a rate of 3.6×106 m³/s of 1.57°C water.[1]

Sunda Trench
Wikipedia (http://en.wikipedia.org/wiki/Sunda_Trench)
The Sunda Trench, earlier known as, and sometimes still indicated as the Java Trench,[1] is located in the northeastern Indian Ocean, with a length of 2,600 kilometres (8,500,000 ft). The maximum depth of 7,725 metres (25,344 ft)[citation needed] (at 10°19'S, 109°58'E, about 320 km south of Yogyakarta), is the deepest point in the Indian Ocean. The trench stretches from the Lesser Sunda Islands past Java, around the southern coast of Sumatra on to the Andaman islands, and forms the boundary between Indo-Australian Plate andEurasian plate (more specifically, Sunda Plate). The trench is considered to be part of the Pacific Ring of Fireas well as one of a ring of oceanic trenches around the northern edges of the Australian Plate.
There is scientific evidence that the recent earthquake activity in the area of the Java Trench could lead to further catastrophic shifting within a relatively short period of time, perhaps less than a decade.[2] This threat has resulted in international agreements to establish a tsunami warning system in place along the Indian Ocean coast.[3]

Sunda Arc
Wikipedia (http://en.wikipedia.org/wiki/Sunda_Arc)
The Sunda Arc is a volcanic arc that has produced the islands of Sumatra and Java, the Sunda Strait and the Lesser Sunda Islands. A chain ofvolcanoes forms the topographic spine of these islands. The arc marks an active convergent boundary between the East Eurasian plates that underlie Indonesia, especially the Sunda Plate and the Burma Plate, with the India and Australian Plates that form the seabed of the Indian Oceanand the Bay of Bengal. The Sunda Arc is a classic example of a volcanic island arc, in which all the elements of such geodynamic features can be identified.
The India and Australian Plates are subducting beneath the Sunda and Burma plates along the Sunda Arc. The tectonic deformation along this subduction zone in the Java Trench (also known as the Sunda Trench) caused the 2004 Indian Ocean earthquake of December 26, 2004.

Challenger Fracture Zone
Wikipedia (http://en.wikipedia.org/wiki/List_of_fracture_zones)
Fracture zones are common features in the geology of oceanic basins. Globally most fault zones are located on divergent plate boundaries on oceanic crust. This means that they are located around mid-ocean ridges and trend perpendicular to them. The term fracture zone is used almost exclusively for features on oceanic crust, similar structures on continental crust are instead termed transform or strike slip faults, a denomination active fracture zones also can have. Some fracture zones have been created by mid-ocean ridge segments that have been subducted and may not longer exist.

Eltanin Fracture Zone
Wikipedia (http://en.wikipedia.org/wiki/Eltanin_Fracture_Zone)
The Eltanin Fault System (Eltanin Fracture Zone) is a series of six or seven dextral transform faults that offset the Pacific-Antarctic Ridge, a spreading zone between the Pacific Plate and the Antarctic Plate. The affected zone of the Pacific-Antarctic Ridge is about 800 km long, between 56° S, 145° W and 54.5° S, 118.5° W,[1] southwest of Easter Island, and about as far as one can get from land on planet Earth.[2] However, the total offset is about 1600 km.[1] The two major faults in the Eltanin Fracture Zone are the Heezen Fault and the Tharp Fault. Others related faults include the Vacquier Transform Fault, the Menard Transform Fault, and the Udintsev Fault.[3]

Mendocino Fracture Zone
Wikipedia (http://en.wikipedia.org/wiki/Mendocino_Fracture_Zone)
The Mendocino Fracture Zone is a fracture zone and transform boundary off the coast of Cape Mendocino in far northernCalifornia. It runs westward from a triple junction with the San Andreas Fault and the Cascadia subduction zone to the southern end of the Gorda Ridge. It continues on west of its junction with the Gorda Ridge, as an inactive remnant section which extends for several hundred miles.
Technically, a fracture zone is not a transform fault, but in the case of the Mendocino, the term has been loosely applied to the active fault segment east of the Gorda Ridge as well as to the true fracture zone segment west of it. Many seismologists refer to the active segment as the Mendocino Fault or Mendocino fault zone. The fault section demarcates the boundary between the northwestward-moving Pacific Plate and the eastward-moving Gorda Plate. The Gorda Plate is subducting beneath the North American Plate just offshore of Cape Mendocino. Where the Mendocino Fault intersects the undersea trench of the subduction zone, it also meets the San Andreas Fault. This seismically active intersection is called a triple junction, and specifically the Mendocino Triple Junction.

The volcano in southwestern Peru blasted back to life causing about 60 villagers from Querapi, near its base, to be relocated Saturday, Ubinas town mayor Pascual Coaquira said.

The 1815 eruption of Tambora and the Little Ice Age
Wikipedia
Throughout the Little Ice Age, the world experienced heightened volcanic activity.[71] When a volcano erupts, its ash reaches high into the atmosphere and can spread to cover the whole earth. This ash cloud blocks out some of the incoming solar radiation, leading to worldwide cooling that can last up to two years after an eruption. Also emitted by eruptions is sulfur in the form of sulfur dioxide gas. When this gas reaches the stratosphere, it turns into sulfuric acid particles, which reflect the sun's rays, further reducing the amount of radiation reaching Earth's surface. The 1815 eruption of Tambora in Indonesia blanketed the atmosphere with ash; the following year, 1816, came to be known as the Year Without a Summer, when frost and snow were reported in June and July in both New England and Northern Europe. Other volcanoes that erupted during the era and may have contributed to the cooling include Billy Mitchell (ca. 1580), Mount Parker (1641), Long Island (Papua New Guinea) (ca. 1660), and Huaynaputina (1600).[19]

2010 Eyjafjallajökull Eruption
Wikipedia
The 2010 eruptions of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. Additional localised disruption continued into May 2010. The eruption was declared officially over in October 2010, when snow on the glacier did not melt. From 14–20 April, ash covered large areas of northern Europe when the volcano erupted. About 20 countries closed their airspace to commercial jet traffic and it affected more than 100,000 travellers.

Adams Seamount
Wikpedia (http://en.wikipedia.org/wiki/Adams_Seamount)
Adams Seamount is a submarine volcano above the Pitcairn hotspot in the central Pacific Ocean about 90 kilometres (56 mi) southwest of Pitcairn Island.
It is a massive seamount rising 3,500 metres (11,483 ft) from the sea floor to about 59 metres (194 ft) below the surface of the ocean.

Axial Seamount
Wikipedia (http://en.wikipedia.org/wiki/Axial_Seamount)
Axial Seamount (also Coaxial Seamount or Axial Volcano) is a seamount and submarine volcano located on the Juan de Fuca Ridge, approximately 480 km (298 mi) west of Cannon Beach, Oregon. Standing 1,100 m (3,609 ft) high,[3] Axial Seamount is the youngest volcano and current eruptive center of the Cobb-Eickelberg Seamount chain. Located at the center of both a geological hotspot and a mid-ocean ridge, the seamount is geologically complex, and its origins are still poorly understood. Axial Seamount is set on a long, low-lying plateau, with two large rift zones trending 50 km (31 mi) to the northeast and southwest of its center. The volcano features an unusual rectangular caldera, and its flanks are pockmarked by fissures, vents, sheet flows, and pit craters up to 100 m (328 ft) deep; its geology is further complicated by its intersection with several smaller seamounts surrounding it.

Banua Wuhu
Wikipedia (http://en.wikipedia.org/wiki/Banua_Wuhu)
Banua Wuhu submarine volcano rises more than 400 m from the sea floor in the Sangihe Islands of Indonesia. Historical records show that several ephemeral islands were formed and disappeared. A 90 m high island was formed in 1835, but then dwindled to only a few rocks in 1848. A new island was reportedly formed in 1889 and it was 50 m high in 1894. Another new island was formed in 1919 but then disappeared by 1935.[1]

The extreme depths and different mineral composition of the seafloor along the Mid- Cayman Rise have produced many different kinds of vents within a relatively short span of seafloor. Researchers on this cruise concentrated their efforts at two sites, one of which, the Piccard vent field, is the deepest known hydrothermal site, at nearly 5,000 meters (3.1 miles) deep. The fluids gushing from some of the vents at this site were found to be just above 400°C (750°F), among the hottest vents known.
