How many times greater is an earthquake of 8 on the Richter scale to an earthquake of 6on the Richter scale?
need help with homework
An increase of 1.0 on the scale is
10 times larger in terms of ground shaking
32 times larger in terms of actual energy release
therefore an increase in 2.0 on the scale is
10×10 = 100 times larger (ground shaking)
32×32 = 1000 times larger (energy release)
Since energy release shows the difference in strength best, 1000x is the answer.
