An earthquake measures 5.2 on the Richter scale. What is the amount of energy released by the quake?. The choices are the following : 1). 105.2 ergs. . 1019.6 ergs. . 1011.8 ergs. . 107.8 ergs.

The Richter scale is a logarithmic scale used to measure the destructive power of an earthquake. For every unit, increase corresponds to approximately a 30-fold increase in the total energy released.
The energy released from a 5.2 Richter scaled quake is:

1). 105.2 ergs

An earthquake occurs when Earth's crust releases stored energy suddenly. Generally, less than 10% of an earthquake's total energy is released in the form of radiated seismic waves. The moment magnitude scale is the one which measures the amount of energy which is released by an earthquake.
