GEOLOGY

Detailed explanation-1: -Tsunamis can be caused by vertical seabed movement that causes a change in the height of the sea surface, like a step, travelling through the water column. When it on collapses under the force of gravity, it travels and spreads outward at great speed.

Detailed explanation-2: -What is a tsunami? A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

Detailed explanation-3: -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.

Detailed explanation-4: -Tsunamis are ocean waves triggered by: Large earthquakes that occur near or under the ocean. Volcanic eruptions. Submarine landslides.

Detailed explanation-5: -Tsunamis are observed not only on the margin of oceans but also in lakes. The majority of tsunamis are generated by earthquakes, but other events that displace water such as landslides and volcanic eruptions can also generate tsunamis.
