7.0 Earthquake in Japan

[Sav]

7.0 is only 2 away from 9.0 guyz.

Run to the hills!

But the hills have eyes!!

Anyway, in all seriousness, Richter is a log-based scale, right? so a 9.0 is 100 times more...earthquake-y?...than a 7.0. I wouldn't be too worried.

Not 100, 1000.

10^9/10^7=10^(9-7)=10^2=cheeseburger

Depends. Are we talking about wave amplitudes, or actual energy released?

From Wiki:

Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to a doubling of the energy released.

I'm so putting that on my next calc exam!
