most likely the electricity is turned off in the area which would turn off the pump. It sounds like the gas station caught fire too quickly to get to the pump shutoff. It's the gases from the fuel that burn so the tank is probably safe if the pump is off and tank is full - gasses build up in tanks with less fuel. Propane is another story and dangerous if it's present at the gas station.
