Hawaii County Civil Defense

Hawaii County Civil Defense is the emergency management agency for Hawaii County on the island of Hawaiʻi. It coordinates hazard monitoring, public alerts, evacuation planning, and disaster response across communities such as Hilo, Kailua-Kona, Pāhoa, Waimea, and Hamakua. The agency operates in partnership with state and federal organizations including the Hawaii Emergency Management Agency, Federal Emergency Management Agency, USGS, National Weather Service, and Hawaii Volcanoes National Park.

History

Hawaii County Civil Defense traces its origins to Cold War-era civil defense structures linked to United States Civil Defense programs and later evolved through responses to natural events such as eruptions of Mauna Loa and Kīlauea, the 1975 eruption near Kalapana, and regional emergencies including Hurricane Iniki planning. The office expanded during the eruption sequence beginning in 1983 at Kīlauea and was further shaped by tsunami events including the 1946 Aleutian Islands earthquake tsunami legacy and lessons learned from the 1960 and 1975 Pacific tsunamis that affected Hawaiian Islands preparedness. Organizational changes have mirrored federal shifts like creation of the Federal Emergency Management Agency and state-level reorganizations under the Government of Hawaii.

Organization and Responsibilities

Hawaii County Civil Defense is structured to interface with county departments such as Hawaii County Fire Department, Hawaii County Police Department, Department of Water Supply, and Public Works. It maintains liaisons with federal partners including FEMA, USGS Volcano Hazards Program, NOAA NWS, and CDC for public health incidents. Responsibilities include coordinating emergency operations center activations modeled after Incident Command System principles used in incidents like responses to 2018 Kīlauea eruption and coordinating shelter operations in collaboration with organizations such as the American Red Cross and Office of Housing and Community Development.

Emergency Operations and Response

The agency manages the county Emergency Operations Center (EOC) and coordinates multi-agency response during activations involving hazards from Kīlauea, Mauna Kea, wildland fires near Puna, coastal inundation from tsunamis originating at the Aleutian Islands or Chile subduction zones, and tropical cyclones like Hurricane Lane. It implements evacuation plans used during eruptive crises in areas such as Leilani Estates and coordinates logistics, resource requests, and mutual aid with neighboring counties like Maui County, Honolulu County, and Kauai County. The office also coordinates with federal response assets such as United States Coast Guard units and National Guard elements when activated under Stafford Act authorities.

Hazard Monitoring and Public Alerts

Hawaii County Civil Defense relies on data and warnings from agencies including USGS, NOAA, NOAA tsunami warning centers, and the National Weather Service for tropical cyclone watches and warnings. It issues public alerts through systems such as the Emergency Alert System, Wireless Emergency Alerts, county sirens in coastal communities, and multilingual notifications tailored to populations in Hilo, Kona, and rural districts. The office has adapted alerting protocols following incidents involving false alerts in other jurisdictions and coordinates hazard maps and real-time information with Hawaiian Volcano Observatory and Pacific Tsunami Warning Center guidance.

Community Preparedness and Education

The agency conducts outreach programs aimed at residents in communities like Pāhoa, Nanawale Estates, and Kohala to increase readiness for lava flows, earthquakes, tsunami, and flooding. Programs include community emergency response teams modeled on Community Emergency Response Team training, school preparedness partnerships with Hawaii Department of Education, and coordination with non-governmental organizations such as the Aloha United Way and Hawaii Foodbank. Efforts also involve collaborating with cultural institutions like Office of Hawaiian Affairs and Hoʻokupuna stakeholders to integrate traditional knowledge into evacuation planning and continuity strategies for critical infrastructure including Hilo International Airport and Pacific Tsunami Museum.

Notable Incidents and Deployments

Significant activations have included responses to the 2018 lower Puna eruption and associated Leilani Estates eruption, tsunami advisories following earthquakes sourced near the Kuril Islands and Chile, and tropical cyclone preparations during storms such as Hurricane Iselle. The office has coordinated evacuations from zones impacted by lava inundation, supported damage assessments after events connected to Kīlauea and Mauna Loa, and participated in regional exercises with entities like FEMA Region IX, Pacific Islands Region partners, and the United States Geological Survey. Deployments have included assistance to remote communities, coordination during 2018 Kīlauea eruption road closures affecting Chain of Craters Road, and public information campaigns during threat periods driven by data from the Hawaiian Volcano Observatory.
