What plate boundary was the Indian Ocean tsunami on?

What plate boundary was the Indian Ocean tsunami on?

The December 26, 2004 M=9.1 Sumatra-Andaman earthquake occurred along a tectonic subduction zone in which the India Plate, an oceanic plate, is being subducted beneath the Burma micro-plate, part of the larger Sunda plate.

What type of boundary is a tsunami?

The word tsunami comes from the Japanese meaning a ‘harbour wave’. Most large tsunamis occur at convergent plate boundaries where two tectonic plates are crashing into each other. As the two plates collide one plate is forced down underneath the other.

What type of convergent boundary causes tsunami?

In subduction zones we see convergent plate boundaries where two plates are colliding with each other and one of the plates is subducting back into the Earth. This type of plate boundary is particularly effective for causing tsunamis.

Do tsunamis occur at divergent boundaries?

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.

Can two tsunamis collide?

It’s possible, but the wave direction and intensity has to be equal and opposite (out of phase) with the tsunami you’re trying to cancel.

What was the worst tsunami ever?

In fact, the largest tsunami wave ever recorded broke on a cool July night in 1958 and only claimed five lives. A 1,720 foot tsunami towered over Lituya Bay, a quiet fjord in Alaska, after an earthquake rumbled 13 miles away.
