The 2004 Indian Ocean earthquake and tsunami was triggered by a megathrust earthquake along the convergent boundary of the Indian plate and Burma microplate and killed over 200,000 people. The 2011 tsunami off the coast of Japan , which caused 16,000 deaths and did US$360 billion in damage, was caused by a magnitude 9 megathrust earthquake ...
The Aleutian Trench, of the southern coast of Alaska and the Aleutian Islands, where the North American plate overrides the Pacific plate, has generated many major earthquakes throughout history, several of which generated Pacific-wide tsunamis, [22] including the 1964 Alaska earthquake; at magnitude 9.1–9.2, it remains the largest recorded ...
From the tsunami records the estimated tsunami's magnitude is ... The trench forms part of the convergent boundary between the Pacific and Eurasian plates. [2]
These two plates meet along a convergent boundary, marked by the trench. The subduction zone is seismogenic and produces Kamchatka earthquakes, which occasionally generate tsunamis. Earthquakes associated with the Kuril-Kamchatka subduction zone are of the megathrust type.
The Kuril Islands form part of the island arc formed above the subduction zone, where the Pacific plate is being subducted beneath the North American plate.This convergent boundary has been the site of many large megathrust earthquakes, including the second largest earthquake ever recorded.
A convergent plate boundary is where a denser oceanic plate is forced under a continental plate in a process known as subduction. [6] When the earthquake occurred, the plates shifted releasing massive amounts of energy and causing a large displacement of water. [7] This water then moves very fast towards land until it approaches the shore ...
It is a megathrust, located at a convergent plate boundary where it forms the interface between the overriding Eurasian plate and the subducting Indo-Australian plate. It is one of the most seismogenic structures on Earth, being responsible for many great and giant earthquakes , including the 2004 Indian Ocean earthquake and tsunami that killed ...
The convergent boundary is the source for many historically documented tsunamigenic earthquakes in 1833, 1940, 1964, 1983, and most recently, the 1993 southwest off Hokkaido earthquake. [ 15 ] Based on analyzing records of the tsunami heights, a large magnitude 7.5–8.4 earthquake along the eastern margin of the Sea of Japan would have been ...
