Hawaii · Preparedness Guide
Active volcanoes, Pacific hurricanes, Pacific Rim tsunamis with 20-minute warning windows, and island isolation that means there is no driving to safety — preparation in Hawaii is a matter of life and geography.
About this guide
Hawaii's hazard profile is unlike any other state. The island chain sits in the middle of the Pacific — both the most isolated major population center on Earth and directly in the path of Pacific hurricanes, tsunamis from earthquakes across the entire Pacific Rim, and its own volcanic activity. Kīlauea on the Big Island is the world's most active volcano; the 2018 Lower East Rift Zone eruption destroyed 716 homes. The August 2023 Lahaina wildfire on Maui was the deadliest US wildfire in over 100 years — it killed 100 people and destroyed historic Lahaina in hours. Tsunamis are the most catastrophic potential hazard — the 1946 Aleutian earthquake tsunami killed 159 people in Hawaii and destroyed Hilo. Island isolation means all food, fuel, and critical supplies must be imported — supply chain disruption is a preparedness concern at a level no mainland state faces.
Local self-reliance starts with knowing your place.
