A significant local tsunami was reported in Lima. The tsunami was confused with that of the Aleutian Islands event in tsunami catalogs. 1586 Lima-Callao earthquake: 28 February 1600 20:00 (local time) Omate, Peru: Unknown 8.1 24 November 1604 13:30 (local time) Arica, Peru: 100 9.0 1604 Arica earthquake: 20 October 1609 01:00 (local time) Peru ...
This subduction zone was responsible for the 2004 Indian Ocean earthquake and tsunami. [15] In parts of the megathrust south of Java, referred to as the Java Trench, for the western part, M w 8.9 is possible, while in the eastern Java segment, M w 8.8 is possible, while if both were to rupture at the same time, the magnitude would be M w 9.1.
A seismogram recorded in Massachusetts, United States. The magnitude 9.1 (M w) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), [9] [56] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
That megathrust earthquake caused a tsunami off Japan’s eastern coast. More than 18,000 people died in the tsunami and earthquake, according to the U.S. National Oceanic and Atmospheric ...
The most important clue linking the tsunami in Japan and the earthquake in the Pacific Northwest comes from studies of tree rings (dendrochronology), which show that several "ghost forests" of red cedar trees in Oregon and Washington, killed by lowering of coastal forests into the tidal zone by the earthquake, have outermost growth rings that formed in 1699, the last growing season before the ...
Variation of seismicity with depth across the Sunda Trench subduction zone, low-angle part is the Sunda megathrust – 2007 Bengkulu earthquakes mainshock shown by star. The Sunda megathrust is a fault that extends approximately 5,500 km (3300 mi) from Myanmar (Burma) in the north, running along the southwestern side of Sumatra, to the south of Java and Bali before terminating near Australia.

Most tsunami earthquakes have been linked to rupture within the uppermost part of a subduction zone, where an accretionary wedge is developed in the hanging wall of the megathrust. Tsunami earthquakes have also been linked to the presence of a thin layer of subducted sedimentary rock along the uppermost part of the plate interface, as is ...
