Earthquake damage scale
The Mercalli Scale, which measures intensity, is another method to measures earthquake damage. The 1931 Modified Mercalli scale used in the United States assigns a Roman numeral in the range I (not felt at all) to XII (buildings destroyed, nearly total damage) to each earthquake effect and measures the overall affects at certain locations. The Richter scale is a base-10 logarithmic scale, meaning that each order of magnitude is 10 times more intensive than the last one. In other words, a two is 10 times more intense than a one and a three is 100 times greater. In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake ...Geology. Getty Images A moderate earthquake registers between 5 and 5.9 on the Richter scale and causes slight damage to buildings and other structures. There are about 500 of these around the globe every year. An earthquake of magnitude 5.5 struck the border between Quebec, seen here, and Ontario in June 2010.

The San Jose Fire ...The Richter magnitude Scale, or local magnitude scale, was developed in 1935 by seismologist Charles Richter as a way to mathematically calculate the magnitude of an earthquake. The Richter Scale uses information from seismographs, such as the amplitude of seismic waves, to assign a magnitude value. These values go from 0 to 10 and are ...Earthquake Magnitude Scales. The severity of an earthquake is generally proportional to the amount of seismic energy it releases. Seismologists use a Magnitude scale to express this energy release. Here are the typical effects of earthquakes in various magnitude …
Aug 4, 2020 · According to empirical structural-damage survey data from the Wenchuan earthquake (Mw = 8.0) that occurred on 12 May 2008 in China, the European Macroseismic Scale (EMS)-98, Medvedev, Sponheuer, and Karnik (MSK)-81, and Chinese Seismic Intensity Scale (CSIS)-08 intensity scales were utilized to evaluate the resulting damage. In the past, the Richter scale (ML) was used to compare earthquakes, calculated in a 10-point scale.
