The earthquake magnitude scale is logarithmic - a 5.9 has shaking 1000 times smaller in amplitude than a 8.9 (which is approximately what those other quakes were). Maybe a dozen 5.9s happen every week. Dude's got a point.

Now, everybody go and fill out this form and crash the USGS servers:

Are Your Bowel Movements Measurable From Space?

Force = mass x acceleration!

You are correct about the last 450,000 years but that doesn't apply to the last 200.

There is no reason why two different processes (tsunamis and warming) can't be happening at the same time! The Earth is a complex system.

If you wouldn't mind...
