Tsunamis Tsunami’s occur when Earth’s oceanic crust shifts, typically after an Earthquake.

Tsunamis Even if Earth’s crust only shifts a little, that energy will build up in the ocean as the ocean floor gets shallower and shallower. Wave heights can be anywhere from 1 to 50 feet above sea level.

Tsunamis Japan’s Tsunami even reached Hawaii. https://www.youtube.com/watch?v=SvbBrFr2EJU

Landslides / Mudslides Landslides occur when weak soil is disturbed by some sort of motion, an Earthquake for example. Mudslides are similar, except much faster and much more wet.
