Earthquake! What does it do, and how do the heroes respond?

[SSgt Baloo]

This is another spawn of the Natural Disasters thread (http://www.herogames.com/forums/showthread.php/78524-Natural-Disasters-What-are-they-and-what-can-the-heroes-do). The main question here is, what effects are needed to model an earthquake, and what sort of actions can heroes take to (best case) halt the earthquake before it can do damage or (usual case) what sort of things can the heroes do to minimize the damage done?

Anyone? Anyone? Bueller?

I see an earthquake as dealing low-level, penetrating or armor piercing damage to any structure firmly connected to the ground, and making it difficult for characters to move around.

Easy-peasy. :)
