The San Andreas Fault in California is an example of a … WebA tsunami is a large ocean wave usually caused by an underwater earthquake or a volcanic explosion. Tsunamis are NOT tidal waves. Tidal waves are caused by the forces of the moon, sun, and planets upon the tides, as well as the wind as it moves over the water. With typical waves, water flows in circles, but with a tsunami, water flows straight.
WebMovement occurs when the seafloor sits on the block of earth's crust that shifts up or down during a quake. 1) EQ rupture in seafloor pushes water upwards starting the tsunami. 2) Tsunami moves rapidly in deep ocean reaching speeds greater than 500 km/hr. 3) As tsunami nears land it slows about about 45 km/hr but is squeezed upwards, increasing ... WebWhen the plates shift suddenly, a large amount of water can be displaced, creating a tsunami.
