What Caused the Indonesian Earthquake? A: The 2004 Indonesian earthquake was caused by the earth's Indian plate moving underneath the Burma plate, causing a massive release of seismic stress and resulting in faults. This led to earthquakes and tsunamis in 14 Asian countries. It is also known as the Indian Ocean earthquake or the Sumatra earthquake. Continue Reading

Indian Ocean Tsunami This is what happened on December 26, 2004 when Sumatra, Indonesia was decimated by an earthquake and tsunami. Sumatra, along with thirteen other countries, was struck by the overwhelming natural disaster and roughly 230,000 people were killed. This became known as the Indian Ocean earthquake and tsunami in 2004.

- Species richness is a count of the number of species in a given habitat or ecosystem. Unlike species diversity, species richness does not take species abundance into account. One factor which is important to consider when measuring species richness is sampling methodology.

- The damage caused can range from little to massive devastation, as seen on December 26th 2004 when an earthquake measuring 9.3 occured off the coast of Sumatra, Indonesia in which 300,000 people lost their lives due to the massive tsunamis that hit the surrounding land.

GROUND MOTIONS OF THE SUMATRA EARTHQUAKES OF 2004 AND 2005 The Sumatra earthquakes of December 26, 2004 (Mw 9.15) and March 28, 2005 (Mw 8.7) are the largest subduction earthquakes that have ever been recorded on modern digital instruments. Both earthquakes were caused by the subduction of the India- Australia plate beneath the Eurasian Plate.

Early warning of disasters: Facts and figures And this year, an earthquake measuring 8.7 on the Richter Scale, which hit off the coast of Indonesia, led to the activation of the Pacific Tsunami Early Warning System; but there were no significant tsunamis, and the likelihood of a tsunami was judged to be low based on the characteristics of the earthquake.

- As we have discussed in class, one possible place earthquakes can occur is at subduction zones. In the case of the 2004 Boxing Day tsunami, a 9.2 magnitude earthquake occurred off the coast of the Indonesian island of Sumatra (USGSa 2008).According to the USGS, the India oceanic plate was being subducted by the Burma microplate which is a part of the larger Sunda plate (USGSa 2008).s we have discussed in class, one possible place earthquakes can occur is at subduction zones. In the case of the 2004 Boxing Day tsunami, a 9.2 magnitude earthquake occurred off the coast of the Indonesian island of Sumatra (USGSa 2008).

How Does a Tsunami Happen? Tsunamis are formed by violent underwater earthquakes, landslides, volcanic eruptions, and, rarely, meteor impacts. These events cause sudden and drastic displacement of water, forming massive waves in the process. Most tsunamis are caused by earthquakes. As a result, most tsunamis occur near or at fault lines. When a tsunami is generated, it is not only 1 wave. Instead it is a series of waves, known as a wave train. These waves travel together and can be up to 1 hour apart. Tsunami waves travel extremely fast with speeds of up to 500 miles per hour—the speed of a jet.

- These earthquakes triggered tsunamis that affected Indonesia and neighbouring countries in Asia (including India, Malaysia, Maldives, Sri Lanka, and Thailand) and the east coasts of Africa (including Somalia and Yemen), causing serious damage to the coastal areas and small islands.

Earthquakes and Tsunamis in Sumatra: What we have recently learned 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. This enormous quake generated the most deadly and damaging tsunami in recorded history.

What caused the Nepal earthquake? Saturday's catastrophic earthquake in Nepal occurred because of two converging tectonic plates: the India plate and the overriding Eurasia plate to the north, the U.S. Geological Survey said. Tectonic plates are the large, thin, relatively rigid plates that move relative to one another on the outer surface of the Earth.aturday's catastrophic earthquake in Nepal occurred because of two converging tectonic plates: the India plate and the overriding Eurasia plate to the north, the U.S. Geological Survey said.

How do tsunamis happen? exists and is an alternate of . A tsunami (Japanese for harbor wave) can be caused when a large volume of water in a sea or ocean is displaced. Tsunamis can happen most anywhere that there is an ocean or giant body of water. They especially happen where major natural events like underwater earthquakes or volcanoes can happen. A tsunami can be generated when convergent or destructive plate boundaries abruptly move and vertically displace the overlying water.

What Causes An Earthquake ? Tectonic Earthquakes. Tectonic earthquakes are triggered when the crust becomes subjected to strain, and eventually moves. The theory of plate tectonics explains how the crust of the Earth is made of several plates, large areas of crust which float on the Mantle.he same events occur in an earthquake. There is a sudden movement within the crust or mantle, and concentric shock waves move out from that point. Geologists and Geographers call the origin of the earthquake the focus.

How Tsunamis Work On March 11, 2011, a magnitude 9.0 earthquake struck off the coast of Honshu, Japan, sparking a tsunami that not only devastated the island nation, but also caused destruction and fatalities in other parts of the world, including Pacific islands and the U.S. West Coast.

Video: 2004 Boing Day Tsunami. The earthquake that generated the great Indian Ocean tsunami of 2004 was an undersea megathrust earthquake that occurred at 7:59 am local time on Sunday, 26 December 2004. It was caused by subduction with an epicentre off the west coast of the Indonesian island of Sumatra.

- The 1906 Ecuador–Colombia earthquake occurred at 15:36 UTC on January 31, off the coast of Ecuador, near Esmeraldas.The earthquake had a moment magnitude of 8.8 and triggered a destructive tsunami that caused at least 500 casualties on the coast of Colombia.ecause the sequence of three earthquakes that ended in 1979 did not release as much energy as the 1906 event, it has been suggested that an earthquake of similar magnitude to that in 1906 was likely in the near future.

Effect of the 2004 Indian Ocean earthquake on Indonesia (January 2010). Indonesia was the first country to be seriously affected by the earthquake and tsunami created by the 2004 Indian Ocean earthquake on 26 December 2004, swamping the northern and western coastal areas of Sumatra, and the smaller outlying islands off Sumatra.or a map of the affected areas in Sumatra see this BBC map. Northern Sumatra took damage from the earthquake itself as a tsunami landed on it. However, most of the damage was the result of the tsunami that struck the coastal regions of the Aceh and to a much lesser extent the North Sumatra provinces.

How tsunami happens? Tsunami are waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean. Most tsunami are caused by large earthquakes on the sea floor when slabs of rock move past each other suddenly, causing the overlying water to move. The resulting waves move away from the source of the earthquake event. View animation to see how undersea earthquakes can cause tsunami.

2004 Indian Ocean earthquake and tsunami The earthquake (followed by the tsunami) was felt simultaneously in Bangladesh, India, Malaysia, Myanmar, Thailand, Singapore and the Maldives. Splay faults, or secondary pop up faults, caused long, narrow parts of the sea floor to pop up in seconds.he 2004 Indian Ocean earthquake came just three days after a magnitude 8.1 earthquake in an uninhabited region west of New Zealand's subantarctic Auckland Islands, and north of Australia's Macquarie Island. This is unusual, since earthquakes of magnitude 8 or more occur only about once per year on average.

Indian Ocean Tsunami One of the unique characteristics about the Indian Ocean earthquake and tsunami in 2004 that sets it apart from others is the fact that there was little to no warning that it was going to happen. The only warning the people of Indonesia had was the hours in between the earthquake and the tsunami. The reason for this was that the Indian Ocean lacked a tsunami warning system because tsunamis are a rarity near the Indian Ocean since the last tsunami it encountered was in 1883.
