Garcetti told KNX 1070 NEWSRADIO officials are working on implementing new cell phone towers that could help ensure your phone works throughout the disaster and recovery.

“I think we could have them last the entire time, even in a big quake, if in the next two years we’re able to build out the plans that we have,” said Garcetti. “Still, you shouldn’t depend on it, you should have a plan.”

Because it may be at least another two years before those cell towers are built, one of the keys to any quake preparedness plan should be having a rally point where family members can meet, Garcetti said.
