A magnitude-6.0 earthquake struck the west flank of the Big Island of Hawaiʻi at 9:46 p.m. On Friday, May 22, 2026. The tremor, which originated at a depth of just over 15 miles, was felt across the island and as far away as Oʻahu and Kauaʻi.
According to the Hawaiian Volcano Observatory, the event was caused by stress from the weight of the Hawaiian island chain bending the oceanic plate and was not related to volcanic activity. There was no tsunami threat associated with the earthquake, and officials reported no apparent impact on the Mauna Loa or Kīlauea volcanoes.
Did You Know? The U.S. Geological Survey received more than 2,660 “Felt Reports” within the first hour of the earthquake, with the furthest report coming from 206 miles away in Wahiawā, Oʻahu.
Damage and Infrastructure Impact
Hawaiʻi County Civil Defense reported that the earthquake caused rock slides on Highway 11 and Nāpōʻopoʻo Road in South Kona, leading to temporary road closures. While those routes were cleared by 6:30 a.m. Saturday, officials have cautioned that debris may remain on road shoulders during final cleanup efforts.
Utility disruptions and property damage have also been documented. Hawaiian Electric noted that while most power was restored, some customers remained without electricity on Saturday morning as crews continued their work. Mayor Kimo Alameda confirmed that Kona Community Hospital sustained minor damage but remained fully operational.
Residents and business owners are encouraged to inspect their properties for damage, particularly regarding gas, water, and electrical connections. Those who sustained damage are asked to report it to Civil Defense online or by calling 808-935-0031.
Expert Insight: While the magnitude of this event is significant, the lack of reported injuries and the continued operation of critical infrastructure like the local hospital suggest that building standards and public preparedness continue to play a vital role in mitigating the impact of seismic events in the region.
Looking Ahead
The Hawaiian Volcano Observatory has advised that aftershocks are a standard expectation following a tremor of this size. While several smaller aftershocks—including a magnitude-3.2 and a magnitude-2.6—occurred shortly after the initial event, experts state that future aftershocks are unlikely to be large enough to cause significant damage.
Authorities continue to monitor the situation and are currently assessing infrastructure across the island. Residents may expect continued monitoring of volcanic and seismic activity by the Hawaiian Volcano Observatory as the recovery process proceeds.
Frequently Asked Questions
Was the earthquake caused by Mauna Loa?
No. The Hawaiian Volcano Observatory stated the quake was caused by stress from the weight of the Hawaiian island chain bending the oceanic plate and was not directly related to volcanic processes.
Are there any tsunami warnings?
No. The National Weather Service reported that there was no tsunami threat from the earthquake.
What should residents do if they have property damage?
Officials encourage residents and businesses to assess their property for damage to buildings, utilities, water catchment, and roadways, and to self-report any findings to Civil Defense online or by calling 808-935-0031.
How are you and your neighbors faring as recovery efforts continue on the Big Island?
