 “I like to remind everyone that it is always appropriate to make a plan for what to do during a disaster, in this case secure your home before, drop, cover, hold on during, and assess damage after; assemble a kit with at least 72 hours of water, food, first aid supplies, flashlight and battery-powered radio in case of utility disruption; and stay informed about our earthquake risks,” Aaron Kenneston, with Washoe County Emergency Management and Homeland Security Program, said.
