Because seismographs were not available prior to 1898, the magnitudes of earthquakes prior to then must be estimated from the intensity of damage associated with the quake as reported by witnesses to the event. Thus, it depends on the amplitude of the surface wave associated with the quake. This value is calculated from the distance that the needle on a seismograph moves during an earthquake. ![]() The magnitudes that the USGS gives for earthquakes after 1898 are similar to the famous Richter scale, in which the magnitude, more or less, represents the energy of the earthquake. Updates on recent earthquakes from 2005 to the present are based on entries in Wikipedia. The magnitude 6.4 quake, the strongest the area has felt in 20 years, was centered.
