Question #d97d1

Answer 1

Th magnitude scale for Earth quakes is a logarithmic scale.

Explanation:

Hope this explantion will make it clear fro m wikipedia "As measured with a seismometer, an earthquake that registers 5.0 on the Richter scale has a shaking amplitude 10 times greater than an earthquake that registered 4.0 at the same distance. As energy release is generally proportional to the shaking amplitude raised to the  3⁄2 power, an increase of 1 magnitude corresponds to a release of energy 31.6 times that released by the lesser earthquake.[1] This means that, for instance, an earthquake of magnitude 5 releases 31.6 times as much energy as an earthquake of magnitude 4 the diagram shows the scale and energy release relation..
