Earthquakes are measured by special machines called seismometers. Scientists use the numbers from 1 to 10 to say how strong an earthquake is. This number system is called a scale, or a magnitude scale. Magnitude means how big or strong something is. Higher numbers mean stronger earthquakes. Earthquakes occur in the crust or upper mantle, which ranges from the earth's surface to about 800 kilometers deep (about 500 miles). The strength of shaking from an earthquake diminishes with increasing distance from the earthquake's source, so the strength of shaking at the surface from an earthquake that occurs at 500 km deep is considerably …Aug 22, 2019 · Preparation.
