The magnitude scale is logarithmic — moving up a level of magnitude means that the strength of the earthquake multiplies, in this case, by a factor of about 31. The energy of a magnitude 4 earthquake is 31 times the energy of a magnitude 3 earthquake. The energy of a magnitude 5 earthquake is 31 times the energy of a magnitude 4 earthquake.The magnitude of an earthquake is expressed in whole numbers as well as in decimal fractions.

Hanks. Size calculations are tied to an earthquake’s seismic moment rather than to the amplitudes of waves recorded by seismographs.Magnitude is an estimate of the relative "size" or strength of an earthquake, and thus its potential for causing ground-shaking. It is "approximately related to the released seismic energy." [1] Intensity refers to the strength or force of shaking at a given location, and can be related to the peak ground velocity.Although there is only one magnitude for a specific earthquake, there may be many values of intensity (damage) for that earthquake at different sites. A magnitude 6.0 quake releases approximately as much energy as 6,270 tons of TNT, a magnitude 7.0 199,000 tons, a magnitude 8.0 6.27 million tons and a magnitude 9.0 99 million tons.Kōbe earthquake of 1995, (Jan. 17, 1995) large-scale earthquake in the Ōsaka-Kōbe (Hanshin) metropolitan area of western Japan that was among the strongest, deadliest, and costliest to ever strike that country. ...

The Moment Magnitude Scale (M) measures the total amount of seismic energy (known as ‘moment’ to engineers and seismologists) released by an earthquake. The moment magnitude scale is a type of logarithmic scale, where each increase of 1 means ~32 times more energy is released. An increase of 2 means that ~1,000 times more energy is released.Sep 19, 2022 · The Latest Earthquake web application displays information in real-time and near-real-time for magnitude 2.5+ earthquakes in the U.S. and magnitude 4.5+ earthquakes around the world.
