The geologist C. F. Richter defined the magnitude of an earthquake to be {image} where I is the intensity of the quake (measured by the amplitude of a seismograph 100 km from the epicenter) and S is the intensity of a "standard" earthquake (where the amplitude is only 1 micron = 10 - 4 cm). The 1,989 Loma Prieta earthquake that shook San Francisco had a magnitude of 7.3 on the Richter scale. The 1906 San Francisco earthquake was 16 times as intense.
