A comment on Nepal earthquake, magnitude 7.3, strikes near Everest. Parent comment
Magnitude of Earthquake M = log I / S
(where I is the intensity of the earthquake taken 100km from epicenter, S is the intensity of a standard earthquake)
First earthquake 7.8 = log I1 / S
Second earthquake 7.1 = log I2 / S
If we solve this for I1/I2, we get 10 ^ 1.10 ~ 12.5
> The intensity of first earthquake was 12.5 times as intense as the later earthquake.
