On what scale are earthquakes measured
WebMost Americans are familiar with the Richter scale, which was developed by seismologist Charles Richter in 1935 at the California Institute of Technology. This scale is based on the largest shock wave recorded by a seismograph 100 km from the earthquake epicenter (the point on Earth’s surface directly above the rupture). WebFrom Richter's (1958) book, Elementary Seismology.(Public domain.) The Richter Scale (M L) is what most people have heard about, but in practice it is not commonly used anymore, except for small earthquakes recorded locally, for which ML and short-period surface wave magnitude (Mblg) are the only magnitudes that can be measured. For all other …
