This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline. The two scales have different applications and measurement techniques. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. The Richter Scale is an absolute scale; wherever an earthquake is recorded, it will measure the same on the Richter Scale.

The Modified Mercalli Intensity Scale The effect of an earthquake on the Earth's surface is called the intensity. Unlike with the Richter scale, the Mercalli scale does not take into account energy of an earthquake directly. This scale is expressed with a logarithmic scale. The Mercalli Intensity Scale is only useful for measuring earthquakes in inhabited areas and is not considered particularly scientific, as the experiences of witnesses may vary and the damage caused may not accurately reflect an earthquake's strength.
