How much more energy releases from a magnitude 2 earthquake compared with a magnitude 1 earthquake?

Earthquake refers to the sudden shaking of the earth due to the release of energy by the seismic ways in the earth's interior. An earthquake of magnitude 2 is exactly ten times bigger, as well as about 31-33 times stronger than that of magnitude 1 .

Richter scale is used to measure magnitude of an earthquake, that means how much energy has been released due to the release of seismic waves.

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.

polar areas, such as antarctica or the south pole.
