World's largest earthquake: Connections to world of wierd science

Link is to a CNN story about how the scientists are flabbergasted. That's a good reason to think twice about what we know, and what we don't know. What are the alternative theories that bear upon this quake?

Exploded Planet Hypothesis: These theorists are probably sweating now.
Expanded Earth Hypothesis: Thumbs up from them, dovetails with their theory.
Velikovskians: Their case is weakened by the fact that large-scale disasters do not always come from space.

Look for expansion upon these ideas in the Gonzo Science column coming out next Thursday in the Reader Weekly of Duluth, MN.
