Geologists use seismic waves to locate the center of an earthquake. D. Geologists use data from three or more data stations to determine the location of the epicenter. E. A seismograph measures the difference between the arrivals of P waves and S waves. What is the main cause of an earthquake? The MM scale measures intensity of shaking, at any particular location, on the surface. It was developed from Giuseppe Mercalli 's Mercalli intensity scale of 1902. While shaking experienced at the surface is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves.The 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.destruction.

These observations and various degrees of destruction are evaluated ...The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes. What is earthquake Mercalli? The Mercalli Scale is based on observable earthquake damage. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. Thus, the magnitude scale is considered scientifically more objective and therefore more accurate.Students will work in a jigsaw format to read through the descriptions of eyewitness accounts from earthquakes and assess a Mercalli value.

Counts toward Master of Disaster badge. Category Earth + Atmospheric Sciences Best for High School + Middle School. The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake.
