quake: Earthquake strengths and locations

Description

The data set quake contains the strengths of earthquakes measured

at the earth's continental plates. Much of the earth's seismic activity

is due to motion of the large plates that make up the crust of the earth.

Earthquakes occur when a buildup in tension between two layers of rock is

suddenly released. For this reason many earthquakes occur at plate

boundaries.
