[BurbankKarl]

Are you going to be mad when the put the dead in piles and torch them?

[Prophet in the wilderness]

Considering the magnitude of the destruction and the lack of fuel to transport the dead bodies, and the destruction of the infrastructure, they have no choice but to either dig huge pits to bury them, or put the dead bodies in piles and burn the dead bodies.
If those relief and rescue people come across hundreds or thousands of bodies in one place and have no way to move then, let alone have time or resources to identify the dead bodies, they will have no choice but to burn them, to keep this from becoming a major health hazard ( not that it is already health hazard ).
