Describe the scales that scientists use to measure the magnitude of an earthquake?

The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.


How much of an increase in wave amplitude is seen from an earthquake measuring 5.4 on the Richter scale compared to one measuring 4.4?

An earthquake measuring 5.4 on the Richter scale would have 10 times higher wave amplitude compared to one measuring 4.4. The Richter scale is logarithmic, so each whole number increase corresponds to a 10-fold increase in amplitude.


What country had an earthquake measuring 7.0 on the Richter scale on Wednesday 02nd September?

What is the Richter scale table?

The Richter scale is used to measure the magnitude of earthquakes. It is a logarithmic scale, meaning each whole number increase represents a tenfold increase in amplitude. For example, an earthquake measuring 7.0 on the Richter scale is ten times larger in amplitude than one measuring 6.0.


How much does the amplitude of the waves increase between an earthquake that measures 4.2 on the Richter scale and an earthquake that measures 6.2 on the Richter scale?

The change in magnitude is (6.2 - 4.2) 2.0. This is equivalent to a 100 times increase in seismic wave amplitude (as each increase of 1 on the scale is a 10 times increase in amplitude therefore 10 * 10 = 100)..


What scale is measured for an earthquakes strength?

Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.
