a earthquake that measures 7.0 to 7.9 on a ritcher scale is called an sichuan earthquake
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.
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)..
Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.
The Richter scale measures the magnitude of seismic waves produced by an earthquake, which provides an estimate of the energy released at the earthquake's source. A higher Richter scale number indicates a stronger earthquake.
it depends on which part of sanfrancisco you are talking about. but all over sanfrancisco the shakes would measure between 6.5 and 7.8 on the Richter scale.
The richter scale!
the Mercalli Scale, the Richter Scale, and the Moment Magnitude Scale

The 2004 Indian Ocean Earthquake measuring 9.3 on the Richter scale. The strongest was in Japan measuring 9.5
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.
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.

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.
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)..
Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.
The magnitude of the 2010 Haiti earthquake on the Richter scale was 7.0
The 2011 earthquake was a 5.8 magnitude on the Richter scale.
