Very interesting as well. 7.8 is a big quake, plenty big enough to make a tsunami. I guess the thing they can't tell from seismic data is the sort of slip that occurred, which will greatly affect the chances of a big wave.

A side slip def won't cause a tsunami, a thrust should almost always, and a normal fault is a possible.
I'd love to see a tsunami rushing up a beach. From a safe distance mind you. |
