The area is bigger, and complicated. I don't know for sure, but it is in Sichuan, that means it is in mountain range. Rescue operation like may needs a lot of choppers, and that posts challenge to air traffic control. The local infrastructures are not available, and make accesses to the affected areas extremely hard. The logistics in this case is much bigger than the war game. Of course, the subsequent earthquakes also post threats. Even for the US, this is not a easy job, let alone China.
