When they are trying to stop the lava with the concrete barriers and you see the television crews reporting on what is happening, how come you don't see any television trucks with their masts up in the air. In order to do a live broudcast you need to either have a satellite truck or a live truck with a mast.
I bet that the trucks are probably hidden behind the firetrucks so that they don't get in the way or get burned if something happens. The reporters don't have to be right up under the bus's butts to do the broadcast.
