Richter scale ground motion

WebJan 15, 2016 · The base of the Richter scale is empirical. In terms of energy released, the best fit for the base turns out to be about 31. Since 31**2 is close to 1000, two points on the Richter scale e.g., from 4 to 6 or from 5 to 7, corresponds to about 1000 times the energy release. Each point piles on another factor of (empirically about) 31. WebThis is because there are many factors of 10 difference between the smallest and largest amplitudes of observed ground motions. An earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger and corresponds to an energy release of 31.6 times greater than one that measures 4.0.

WebThe Richter scale, developed in the 1930s by Charles Richter, is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic … WebPlug magnitude values of 5.0, 6.0, and 7.0 into the equation above. The energy released by an M5 earthquake is about 2.8 x 10 12 joules. An M6 earthquake releases 7.8 x 10 13 joules, and an M7 radiates 2.1 x 10 15 joules. If you don't have a sense for what these numbers mean, the bomb dropped on Hiroshima released about 7.4 x 10 12 joules. http://eqseis.geosc.psu.edu/cammon/HTML/Classes/IntroQuakes/Notes/earthquake_size.html bar 7 saumur

WebMay 29, 2015 · The local ground motion (period, acceleration and duration) during an earthquake vary with location due to factors such as underlying geology, fault mechanism, and orientation to fault. This is one reason that following an earthquake seismologists construct a map of earthquake intensity. WebThe Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.
