This scale is based on how individuals perceive the effects of an earthquake...
The Mercalli scale
The Richter scale

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?
The strong ocean currents are undermining both areas causing earthquakes.
Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.
Both areas are subjected to strong ocean wind and waves that causes earthquakes.
Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.
Earthquakes that occur closer to the Earth's surface tend to be...
of larger magnitude and high intensity which cause severe damage
of larger magnitude and low intensity which cause minimal damage
of smaller magnitude and low intensity which cause minimal damage
of smaller magnitude and high intensity which cause severe damage
