Want this question answered?
A submarine earthquake causes a tsunami.
the motion is called seismogram
It is called the epicenter which is the starting point.
This area is called the fault line.
An earthquake is a force craking in the air.
seismogram
Earthquake
The maximum ground motion of a magnitude 5 earthquake is 100 times larger than a magnitude 3 earthquake.
The epicenter, a point on the earth's surface directly over the focus, is where the first motion of an earthquake will be felt.The first motion of an earthquake is created at the focus, the point deep underground where the first break in the fault line occurs.
The focus of an earthquake is the point along a fault at which the first motion of an earthquake occurs.The epicenter of an earthquake is the point on Earth's surface directly above an earthquake's starting point, or focus.
Movements of tectonic plates against each other usually causing a jarring motion which causes an earthquake.
-3.0 magnitude or if you want the ground motion: Each time the magnitude increases by one unit, the measured ground motion becomes 10 times larger. For example, an earthquake with a magnitude of 5.0 on the Richter scale will produce 10 times as much ground motion as an earthquake with a magnitude of 4.0. Furthermore, an earthquake with a magnitude of 6.0 will produce 100 times as much ground motion (10 × 10) as an earthquake with a magnitude of 4.0.
