5/23/2026, 9:25:42 PM
Event Overview
At 9:46 p.m. local time on May 22 2026, a magnitude 6.0 earthquake struck the western flank of Mauna Loa on Hawaii Island, centered approximately 7 miles south-southeast of Honaunau-Napo‘opo‘o. The USGS reported a hypocentral depth of about 14 miles (?22 km). A magnitude 3.2 aftershock followed six minutes later; a magnitude 4.0 event occurred shortly after midnight. The Pacific Tsunami Warning Center issued a notice that no tsunami was generated.
Geological Context
Scientists from the USGS Hawaiian Volcano Observatory (HVO) explained that the quake’s depth, location, and seismic-wave pattern indicate stress caused by bending of the Pacific oceanic plate under the weight of the Hawaiian island chain. The agencies emphasized that the event was not directly linked to volcanic activity at Mauna Loa or Kilauea.
Official Statements & Responses
- USGS/HVO: “The depth, location, and recorded seismic waves … suggest that it was caused by stress due to bending of the oceanic plate … the earthquake was not directly related to volcanic processes.”
- Pacific Tsunami Warning Center: Confirmed “no tsunami is expected.”
- Hawaii Civil Defense: Advised residents to “be aware of the possibility of after-shocks” and to inspect utilities for damage.
- Hawaii County Police: Closed Napoopoo Road and Route 11 temporarily due to large rocks and debris; roads reopened by 6:30 a.m. the following morning.
On-the-Ground Impact
Former reporter Lacy Deniz described her home shaking side-to-side, glass falling from cabinets, and a cracked toilet. Residents on Oahu, Maui, and Kauai reported strong shaking, with some describing the sensation as comparable to earthquakes in California.
Damage Assessment & Statistics
- USGS “Did You Feel It?” platform recorded 2,500–2,600 reports within the first hour, rising to over 5,800 by 2 a.m.
- Light to moderate structural damage was noted on the west side of the island, including broken glass, displaced furniture, and a water-main break on Highway 11.
- Road debris and landslides were reported along Highway 11 from Captain Cook to Ocean View.
- Farm damage estimates range from $40 million (farm advocates) to $50 million (Hawaii Farm Bureau), affecting roughly 600–2,000 farms.
Criticism & Infrastructure Concerns
Local officials highlighted the immediate hazards of debris-blocked roadways and a water-main rupture, underscoring vulnerabilities in critical infrastructure. Residents expressed frustration over road closures that impeded emergency response and daily travel.
Conflicting Reports & Gaps
- Magnitude: Initially listed as 5.9, later upgraded to 6.0.
- Depth: Reported as 14 miles, 13 miles, and 22 km across sources.
- Felt-Report Counts: Figures range from 2,500 to over 5,800.
- Economic Impact: Damage estimates vary between $40 million and $50 million.
- Aftershock Magnitudes: Sources cite 3.2 and 4.0 events; precise timing differs.
Verbatim Quotes
- “It was quite terrifying. It was very violent,” — Lacy Deniz, former Hawaii News Now reporter
- “My son was crawling on the floor, so my mom had to stand over my son and shield him because all the glass was coming out of the cabinets and falling on the floor.” — Lacy Deniz
- “Earthquake strongly felt in Honolulu, Hawaii,” — M. Makelani Tuha, X user
- “My building in Kakaako was shaking so hard I thought it might collapse for a second. Freaky! Be safe out there everyone! View 2 Images Hawaii is hit with earthquakes several times a year” — Liane Mark, X user
- “Yo! I felt that earthquake here on Kaua’i!!! Has to be bigger than 5.9! Crazy!” — Kauai resident, X post
Outlook
Authorities continue to monitor aftershocks, advise the public to report structural or utility damage, and maintain heightened vigilance of transportation routes and water infrastructure as the region transitions from immediate response to longer-term assessment.
