It's not easy to reach a destination with a great mess after a natural disaster. The infrastructure is trashed to pieces, and debris are everywhere, including the streets. Travel by air is the last resort, but you need to find areas to land. There is a need for time to analyze the damage of infrastructure, where ground vehicles can reach and cannot reach. That may take up to hours. You also need vehicles to remove the debris on the road so ground vehicles may access to the area of disasters, and you need to make calcuations how much human resource is needed, as well as survival equipment. Regarding rescue robots, I imagine its capabilities are very limited. I would not underestimate its searching capabilities, but with large amount of debris, communication between the controller and the rescue robot is likely difficult. Wireless communication must be strong enough to reach the core of the debris. That could be difficult when you are facing urban megaclass buildings with debris of concrete and metalic wires trashed around. This is also the problem urban warfare robots will likely encounter, in terms of operating indoors. Cables may be the last resort, but the length of cables are limited, and could tangle with an obstacle.

The article on "rescue-bots" echoes questions of my own following the deaths in West Virginia. It was hard for me to believe that ten hours had to elapse before rescuers could descend; granted there was a risk of further collapses if another explosion was touched off, but surely a small team wearing personal breathing systems and carrying oxygen for the victims could've saved lives. Or at least tried!
Alas I know nothing about underground rescues; no doubt there are good reasons for them to tarry. What are they?
