The Earth Scientist, 21(2), 30. FORESHOCK: The 2002 Sumatra earthquake occurred at 01:26 UTC on 2 November. Control rotation, wave speed, choose various famous quake presets. The epicentre of the quake was off the west coast of Sumatra. In Banda Aceh, the landmass closest to the quake’s epicenter, tsunami waves topped 100 feet. The December 26, 2004 Sumatra–Andaman, M w 9.1–9.3 giant earthquake happened to be the first indication that the algorithm designed for prediction of M8.0+ earthquakes can be rescaled for prediction of mega-earthquakes. The day after Christmas (December 26, 2004), a large magnitude earthquake occurred just west of the island of Sumatra along a subduction boundary between two tectonic plates.

The Sumatra Earthquake and Tsunami of December 2004: A Comprehensive Inquiry-Based Exercise for High School Earth Science Classes. 5. The tsunami generated by the earthquake was recorded nearly world-wide and killed more people than any other tsunami in recorded history, almost 230,000 missing and presumed dead.
A strike-slip Macquarie Ridge earthquake on May 1989, which had a similar magnitude (Mw 8.1) to the December 2004 earthquake, generated a small tsunami. The people of Sumatra, Indonesia, have been at the mercy of many recent major earthquakes.

The magnitude 9.1 Sumatra-Andaman earthquake of December 26, 2004, was one of the largest earthquakes ever recorded. It had a magnitude of 7.3 on the moment magnitude scale with an epicentre just north of Simulue island and caused three deaths. This enormous quake generated the most deadly and damaging tsunami in recorded history.

This earthquake is regarded as a foreshock of the 2004 Sumatra earthquake, which had an epicentre about 60 km to the northwest. An interactive 3D simulation of earthquake waves traveling the surface and interior of Earth. This enormous quake generated the most deadly and damaging tsunami in recorded history. . On 26 December 2004, a magnitude 9.1 earthquake (3.316 N, 95.854 E, depth 30 km) occurred off the coast of northern Sumatra, Indonesia. The Boxing Day 2004 Earthquake: A Holiday's Worst Nightmare. It is the second largest earthquake ever recorded on a seismograph. The humanitarian response to the 2004 Indian Ocean earthquake of a magnitude of 9.1 was prompted by one of the worst natural disasters of modern times. A strike-slip Macquarie Ridge earthquake on May 1989, which had a similar magnitude (Mw 8.1) to the December 2004 earthquake, generated a small tsunami. The people of Sumatra, Indonesia, have been at the mercy of many recent major earthquakes. Immediately to the south of the great 2004 earthquake, the M 8.6 Nias Island earthquake of March 28, 2005 ruptured a 400-km section between Simeulue and the Batu Islands. The great M 9.1 earthquake of December 26, 2004, which produced a devastating tsunami, ruptured much of the boundary between Myanmar and Simeulue Island offshore Banda Aceh.
