Earthquake shakes the ocean floor storm above the earth.

The storm seism combination that shakes the earth. An earthquake is the ground shaking caused by a sudden slip on a fault. The location below the earth s surface where the earthquake starts is called the hypocenter and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks.

It moves the ground surface up and down. In earthquake records they identified more than 4000 earthquakes from faults in the ocean floor west of sumatra in indonesia from 2004 to 2016 many of them between magnitude 3 5 and 5. Throwing up those giant waves causes pressure to rise on the ocean floor as the waves go up and down it creates a pounding effect. Stresses in the earth s outer layer push the sides of the fault together.

Scientists can t predict earthquakes but they. Rayleigh waves or ground roll travel like ocean waves over the surface of the earth. At that point all the pent up energy is released in ripples or seismic waves that literally shake the land sitting on the earth s crust. Stress builds up and the rocks slip suddenly.

Strong ocean swells hammer ridges in the seafloor and produce the earthquake like shaking in august 2009 hurricane bill shown tracked northwest from puerto rico toward newfoundland. They cause most of the shaking at the ground surface during an earthquake. Earthquakes do not have seasonality. When a large earthquake occurs on the ocean floor that s when you have to worry about the potential of a tsunami but those earthquakes usually clock in at a 7 6 magnitude or higher.
