The possibility of delayed damage due to fire is very real in this band. The energy in the thermal pulse will still be sufficient to start combustible materials on fire, yet the overpressure and accompanying wind will be less likely to put out these fires. If only a small percentage of the buildings start on fire many may be damaged as the fire spreads out of control since the capability to fight fires will be non-existent. It may be 24 hours or more before the resources are available to even begin to fight fires.
