I came across an interesting video on three massive earthquakes and the thrusts that caused tsunamis.

Just because an earthquake is large, i.e., mag 7 or mag 8 or greater, and in the ocean doesn't mean it will produce a tsunami. It does depend on the depth and location as well, and how much elastic energy is stored in the mass (or volume) of crust, and the displacement.

Hi Astronuc

interesting video describing why there are variations in tsunami height

from what I have so far read, this latest Chilean event produced a tsunami of only ~ 2 metres ( fortunately!!)

Would have been good to have seen what reasons they had considered specifically for the Sumatran event

cheers
Dave
