the magnitude r (on the richter scale) of an earthquake of intensity i is defined as where minimum intensity used for comparison. ms. cohen felt an earthquake in los angeles that had an intensity of . what was its magnitude, to one decimal place, on the richter scale? be sure to show and explain your work.



Answer :

A higher measure of the scale of an earthquake is the amount of electricity released by means of the earthquake, that is associated with the Richter Scale via the following equation: Log E = 11.eight + 1.five M (in which Log refers back to the logarithm to the bottom 10, E is the power released in ergs and M the Richter importance).

Richter scale (ML), quantitative measure of an earthquake's magnitude (size), devised in 1935 by way of American seismologists Charles F. Richter and Beno Gutenberg. The earthquake's importance is determined using the logarithm of the amplitude (height) of the biggest seismic wave calibrated to a scale with the aid of a seismograph.

An earthquake has best one importance decided from measurements on seismographs. the primary widely-used size changed into the Richter scale. it's far now taken into consideration old and the instant importance Scale (Mw) is deemed more correct - a robust earthquake might be generally described as 8.five Mw value.
