# Richter Scale and Severity of Earthquakes : Energy and Magnitude

Not what you're looking for?

The Richter Scale provides a comparative measure of the severity of earthquakes. The original formula developed in 1935 was: R = logE, where R is the magnitude on the Richter Scale and E is the energy of the of the earthquake.

(a) How much stronger than a 5.0 is an earthquake that measures 7.0 on the Richter Scale?

(b) What would the Richter measure be for an earthquake with an energy level of 10,000 units?

(c) What is the Richter measure for an earthquake with twice the energy of one that measure 5.0 on the Richter Scale?
