Detailed explanation-1: -On the so-called Richter scale, a magnitude 8 on a seismogram was 10 times bigger than a magnitude 7.
Detailed explanation-2: -Richter Scale However, the energy released by a seismic wave is 101.5 (or about 31.6x) the amount of its amplitude, meaning that a 7.0 quake releases 31.6 times more energy than a 6.0 quake, or 1, 000 times more energy than a 5.0 quake.
Detailed explanation-3: -In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960. The moment magnitude for this event was measured at 9.5.).
Detailed explanation-4: -1 higher magnitude is a 10 times stronger earthquake so a magnitude 8 is 10, 000 times stronger than a magnitude 4.
