GROUND MOTIONS OF THE SUMATRA EARTHQUAKES OF 2004 AND 2005 These regional recordings shown strong spatial variations in amplitude and duration that are consistent with rupture directivity effects. The duration of ground motion of the December event to the north in Thailand was about 600 seconds, while the duration in other directions, including Sumatra, was about 1,000 seconds.

The causes and effects of the 2004 Asian Tsunami The Asian tsunami of 2004 was caused by tectonic activity beneath the Indian Ocean. A fault twenty miles below the ocean surface ruptured, forcing one of the plates to be thrust upwards by as much as 40 feet. The ocean above was forced upwards and the displaced water moved out as a series of giant ripples.

- The earthquake, which is the third largest in the world since 1900, caused severe damage and casualties in northern Sumatra, Indonesia, and in the Nicobar Islands, India. The tsunami that followed killed more people than any other tsunami in recorded history, with 227,898 dead or missing.

- Causes. An earthquake is the shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics). Earthquakes can happen along any type of plate boundary.Earthquakes occur when tension is released from inside the crust. Plates do not always move smoothly alongside each other and sometimes get stuck. When this happens pressure builds up. When this pressure is eventually released, an earthquake tends to occur.arthquakes can happen along any type of plate boundary. Earthquakes occur when tension is released from inside the crust.

Effect of the 2004 Indian Ocean earthquake on Indonesia Teunom, a town in the Memphis district of the special territory of Aceh on the island of Sumatra in Indonesia, with a population of about 18,000, was reported to have been damaged so severely that it  vanished completely leaving only scattered shards of concrete as a result of the tsunami produced by the 2004 Indian Ocean earthquake.

- Earthquakes are caused by shifts in the Earth's crust, and normally occur when rock layers move past each other along a boundary, or fault line.

Multiple deaths confirmed after 7.9 earthquake sparks tsunami fears in Australia and Indonesia where locals run for higher ground Several people have reportedly died in the wake of a 7.9 magnitude earthquake off the west coast of Sumatra in Indonesia. Tsunami warnings were issued in Indonesia and parts of Australia, spreading panic in some provinces of Sumatra, areas which were the worst affected by the 2004 Indian Ocean quake.

Effect of the 2004 Indian Ocean earthquake on Indonesia 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.

The Causes of Earthquakes But what causes all that shaking in the first place? Earthquakes happen deep underground along tectonic plate boundaries. Tectonic plates are what make up the earth's crust, its outermost layer. These plates fit together like puzzle pieces but they don't stay in one place. They're always moving because the part of the earth underneath them is like a fluid.

TSUNAMI SCIENCE The causes of a tsunami are the plates when they shift against each other. In a divergent plate boundary, the plates move away from each other. Where there is a convergent plate boundary the plates push toward each other or collide. Transform boundaries are formed where plates shift past each other horizontally.SUNAMI SCIENCE. Tsunamis are a force to be reckoned with. And that goes for creating them in 3D as well. The challenge was to explain to the viewers how tectonic plates work underneath the ocean floor.

- Rockhound. Plate tectonics cause earthquakes, and volcanoes. When the plates move they built up stress and when the faults release the fault cause and earth quake. There are different types of earthquakes that happen when plate collide. The main force that makes the earth move and tectonics plates form is the outer layer of the earth called lithosphere. They are what creates mountains to become higher a … nd the oceans to become wider because of the earth faults and folds. Sarahroxoutofhersox1.

How tsunami happens? 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.

Nepal earthquake: Dozens die in new tremor near Everest In April, we saw the fault boundary rupture eastwards for 150km (93 miles). And the immediate assessment suggests Tuesday's tremor has occurred right at the eastern edge of this failure. In that context, this second earthquake was almost certainly triggered by the stress changes caused by the first one.

What Causes Earthquakes: Information about Faults, Plate Tectonics and Earth Structure An earthquake is the ground shaking caused by a sudden slip on a fault. Stresses in the earth's outer layer push the sides of the fault together. Stress builds up and the rocks slip suddenly, releasing energy in waves that travel through the earth's crust and cause the shaking that we feel during an earthquake.

- Causes. An earthquake is the shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics). Earthquakes can happen along any type of plate boundary. Earthquakes occur when tension is released from inside the crust.arthquakes are caused by the release of built-up pressure inside the Earth's crust. An earthquake's power is measured on the Richter scale [Richter Scale: A logarithmic scale used to measure the impact of an earthquake by measuring the amount of energy it generates. ] using an instrument called a 'seismometer'.

What Caused the Chilean Earthquake? Faults Explained It really takes the movement of crustal plates to uncork a massive earthquake, such as the magnitude 9.0 quake off the coast of Japan in 2011, which was caused by the Pacific plate moving under Asia. But humanity has figured out ways to trigger small quakes as well.

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.

- Massive sea surges triggered by an earthquake under the Indian Ocean have killed over 10,000 people in southern Asia, with many more feared dead. An 8.9 magnitude earthquake under the sea near Aceh, north Indonesia, at 0759 local time (0059 GMT) generated the biggest tsunami the world has seen for at least 40 years. The wall of water fanned out across the Indian Ocean at high speed and slammed into coastal areas with little or no warning.

Cochise College Student Papers in Geology The tremors of the earthquake caused the pendulum to swing. The lines caused by the pendulum indicated the amplitude of the ground motion. In Calabria, Italy, a series of earthquakes in 1783 that killed over 50,000 civilians. Because of these earthquakes, more mechanical devices were created (Kauffman and Judson 181).
