Magnitude 6.0 Earthquake Shakes Hawaii’s Big Island

Because scientists say the quake reflects tectonic flexing of the oceanic plate, monitoring has been intensified after HVO models showed a possible Kīlauea eruptive window from May 24 to May 27.

Overview

  • Late Friday night a magnitude 6.0 quake struck just south of Hōnaunau‑Nāpōʻopoʻo on the Island of Hawaiʻi, producing strong shaking across multiple islands and a series of aftershocks.
  • The Pacific Tsunami Warning Center issued no tsunami threat and the USGS posted a Green alert for fatalities with a Yellow alert for economic losses while thousands of residents submitted felt reports.
  • Hawaii County reported rockslides on Highway 11, downed utility lines, power outages and minor structural damage including to some homes and Kona Hospital, and crews worked overnight to clear debris.
  • USGS and HVO said the event is consistent with bending stress on the oceanic plate rather than a direct volcanic trigger, but HVO forecast models indicate Kīlauea could produce another eruptive episode between May 24 and May 27.
  • Officials warned more aftershocks are likely, emphasized the low chance of widespread casualties, and urged residents to report damage, avoid closed roads and follow local advisories as repairs continue.
