Use the Richter scale to compare the size and magnitude of earthquakes. Sometimes earthquakes are strong enough to cause a huge amount of damage—high-.On the scale That is a HUGE difference from one number on the scale to the next. According to the USGS an earthquake with a magnitude of 8.7 is about 23,000 times stronger than an earthquake with ...Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.6.1 - 6.9.

Moment magnitude numbers scale such that thatAnnals of Seismology The Really Big One An earthquake will destroy a sizable portion of the coastal Northwest. The question is when. By Kathryn Schulz July …Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. 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. Each whole number step in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value. Another important scale used by earthquake scientists is the Modified Mercalli Intensity (MMI) scale. The MMI scale estimates the intensity of shaking in the region around the ...Using your compass, draw a circle with a radius equal to the number you came up with in Step #2 (the radius is the distance from the center of a circle to its edge).
