It wasn't an earthquake. Craig is just trying for another daughter.
It doesn't help that one of the cities that got it worst doesn't have buildings well-equipped for earthquakes. On top of that, near the coast, there were about one and a half to two and a half metres (5-8 feet) of water in some places. The only thing worse than a natural disaster of this caliber, is not being prepared for this type of natural disaster.
I wonder if Craig was affected by it, and if so, how bad.
