So the question is … "how robust are trunked radio systems that are used in the public safety sector for police and fire departments?" This first check didn't discover any drills or mentions of how trunked radio systems are affected by earthquake, tornadoes, hurricanes, etc when multiple towers are destroyed. Questions arise regarding whether there would be total failure or limited or hampered communications. This initial search did not find any mention of drills that would prepare firefighters and police officers for operations without communications. There was some mention of hybrid communications systems with overlayed conventional systems that would provide service in the event that the trunked system failed. One document mentioned that the failure of a single control channel in a system with only one control channel would take down the entire system.

Curiously, one of the documents in the top seven search results goes back to May 1999.
