What kind of plate boundary caused the earthquake that caused the tsunami on 12 26 04 convergent subduction divergent transform convergent collision?
A sudden shift at a convergent boundary can cause an earthquake and a tsunami like that of December 26, 2004. In the case of a convergent boundary between two oceanic plates, one is usually subducted under the other, and in the process a trench is formed.
What plate boundary caused the 2004 tsunami?
On 26 December 2004 a tsunami occurred in the Indian Ocean. It was the result of the Indio-Australian Plate subducting below the Eurasian Plate. It was caused by an earthquake measuring more than magnitude 9.
What caused the tsunami?
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.
Do divergent plate boundaries cause tsunamis?
In a divergent plate boundary, the plates move away from each other. … If the there is a shift, like an earthquake, on the ocean floor and a plate boundary rises or falls, it displaces the water above. The destructive force causes a tsunami to form. Volcanic eruptions and underwater landslides can also cause tsunamis.
What kind of geological fault is needed for formation of tsunami?
Earthquakes generally occur on three types of faults: normal, strike-slip, and reverse (or thrust). Tsunamis can be generated by earthquakes on all of these faults, but most tsunamis, and the largest, result from earthquakes on reverse faults.
What tectonic plates caused the 2011 Japan tsunami?
In Northeast Japan (Tohoku), the Pacific plate is subducting northwestward beneath the Okhotsk plate, causing the 2011 Tohoku-oki earthquake. Subduction is a process where one of Earth’s tectonic plates sinks under another.
What tectonic plates caused the Indonesian earthquake 2018?
The January 15 event was a shallow crustal earthquake at the boundary between the Sunda plate and the Banda Sea microplate at a focal depth of 18 km. The earthquake occurred along the Mamuju–Majene thrust fault, which is known to be an active seismic source that has caused several deadly earthquakes in the recent past.
