The Richter Magnitude Scale is one method for measuring the intensity of earthquakes. An earthquake's magnitude is the logarithm of the amplitude of waves. The waves are detected by seismographs. Remember, because the Richter Magnitude Scale is logarithmic, each whole number increase in earthquake level means a tenfold ... 10-15. 8.0 or greater. Great earthquake. Can totally destroy communities near the epicenter. One every year or two. Modified Mercalli Intensity Scale. Top. Magnitude scales can be used to describe earthquakes so small that they are expressed in negative numbers. The scale also has no upper limit. Geology. The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth’s surface and on humans and their structures. Several scales exist, but the ones most commonly used in the United States are the Modified Mercalli scale and the Rossi-Forel scale.This paper presents a novel method for estimating the seismic peak interstory drift ratio (IDR) in reinforced concrete (RC) columns after an earthquake using surface crack image analysis.

A network

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 ...The following table provides a comparison between earthquake intensity levels as measured by the Mercalli scale and their approximate magnitude on the Richter scale.

To get a better idea of the strength of the shaking and damage, 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.
