Earthquake Update
While some troops have arrived at the area of the epicenter, progress is extremely slow because everything is being carried in by foot. In addition to the damage to the roads and rail lines, there is heavy rain in the area making aerial drops impossible. The survivors are staying away from the few buildings still standing because of the continuing after shocks, so they are cold, wet and hungry.
Rescue efforts are generally human-powered, and there are relatively few professional teams with the necessary tools available.
Until there is a break in the weather, nothing large scale can be attempted. Thousands are walking in to help, carrying what they can.
