What was the 1906 San Francisco earthquake originally called?
An Earthquake (also known as a quake or tremor) is a shift in the earth’s crust that releases a substantial amount of energy. The size, type and frequency of an earthquake is measured by its seismic activity. The shifting of the surface during an earthquake can cause catastrophic damage to any nearby population. The magnitude of an earthquake is measured on the Richter scale. The Richter scale rates the size of the earthquake from 1 to 10+ with 10+ being the worst.
