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.Apr 27, 2020 ... The Richter scale is best used to measure the strength of small, nearby earthquakes. What is an Earthquake? An earthquake may be defined as a ...Measuring Earthquakes. The vibrations produced by earthquakes are detected, recorded, and measured by instruments call seismographs. The zig-zag line made by a seismograph, called a "seismogram," reflects the changing intensity of the vibrations by responding to the motion of the ground surface beneath the instrument. Earthquakes vary widely, from imperceptible to devastating strengths. So the scale was designed such that each point represents ten times more shaking than the one before it. For example, an earthquake measuring 4.0 on the Richter Scale has ten times the magnitude of a 3.0 earthquake. And so it goes, point by point, across the whole scale.Moment magnitude, a quantitative measure of an earthquake’s magnitude (or relative size), developed in the 1970s by Hiroo Kanamori and Thomas C. Hanks. Size calculations are tied to an earthquake’s seismic moment rather than to the amplitudes of waves recorded by seismographs.Quakes likely to cause the most destruction measure 7.0 and above. The 2004 earthquake which triggered the Asian tsunami was the third biggest quake since 1900. It measured 9.3.Most earthquakes occur along the boundaries between the Earth’s tectonic plates. The crust of the Earth is divided into plates. When a plate collides with or slides past another plate, this causes earthquakes.An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Find 23 millimeters on the right side of the chart and mark that point. Place a ruler (or straight edge) on the chart between the points you marked for the distance to the epicenter and the amplitude.
