Tsunamis (D) usually generated by undersea Earthquakes or activity under the ocean floor, and categorized into natural phenomena caused by nature.
What do undersea earthquakes cause?
- When a great earthquake ruptures, the faulting can cause vertical slip that is large enough to disturb the overlying ocean, thus generating a tsunami that will travel outwards in all directions.
- A tsunami is a sequence of massive waves caused by an underwater disturbance, most commonly earthquakes that occur underneath or near the ocean. A tsunami can be caused by volcanic eruptions, undersea landslides, and coastal rock falls, as well as a massive asteroid slamming the ocean.
