Question

by how many times is an earthquake of magnitude 5 on the richter scale more powerful than one of magnitude 4.
I want class 8 standard answer

Answer 1

The magnitude scale is logarithmic. That just means that if you add 1 to an earthquake's magnitude, you multiply the shaking by 10. ... For example, if the magnitude of one quake is 6 and another is 4, than the difference in magnitudes is 2, so the stronger earthquake shakes 10^2 or 100 times as hard as the milder one.
