Why smartphones are vital in disasters and how to prepare for outages

Power outages affecting half a million Midwestern residents, storm-related blackouts in Hawaii, wildfire evacuations in the western United States and a major quake in Colombia all underscored smartphones as a core part of modern emergency response. People use phones to receive alerts, locate shelters, contact loved ones and call 911, yet disasters can strip away battery life, signal and devices themselves. This vulnerability expands the digital divide from mere access to the reliability of critical information during emergencies.

To mitigate the risk, planners are urged to provide backup channels like radio broadcasts, television alerts, traffic-sign warnings and community centers that can serve as information hubs and charging stations. Initiatives such as New York City’s Notify NYC program and Miami-Dade County’s integrated alert system demonstrate how multiple platforms—including text, email, calls, social media, ASL videos and traditional media—can reach diverse populations, including those with disabilities. Individuals are also advised to keep printed emergency contacts, plan meeting points, and conserve phone battery for essential use while preparing physical copies of vital information in waterproof containers.
