6.0 magnitude earthquake shakes Hawaii, no tsunami threat reported

Strong shaking rippled across Hawaii after a magnitude 6.0 earthquake struck south of Honaunau-Napoopoo at 9:46 p.m. Hawaii time Friday, with residents from South Kona to Kauai and Niihau reporting that they felt it. The Pacific Tsunami Warning Center said no tsunami was generated and no tsunami warning was in effect, easing the main concern that often follows a large offshore quake.

The U.S. Geological Survey first listed the event at magnitude 5.9 before upgrading it to 6.0. Its event pages placed the epicenter about 6 kilometers east-southeast of Honaunau-Napoopoo on one update and about 12 kilometers south of the community on another, with depths reported at 16.1 kilometers and 22.4 kilometers. Those figures point to a quake centered beneath the Island of Hawaii’s volcanic flank, a setting that can produce strong ground motion without the kind of seafloor displacement that drives a tsunami.

Public response to the shaking was immediate and widespread. The USGS said its felt-report system drew 5,804 responses tied to the main event, with reports arriving from across the island chain. The shaking was strong enough to be noticed far beyond the epicenter area, reaching communities as distant as Kauai and Niihau. A magnitude 3.2 aftershock followed six minutes later, and additional smaller aftershocks were recorded in the hours after the main quake.

Officials reported no major damage or casualties in the initial hours after the earthquake. The Hawaiian Volcano Observatory said it was assessing Kīlauea after the quake, while early checks showed no apparent impact to either Kīlauea or Mauna Loa. The event still underscored how quickly earthquake response and volcanic monitoring overlap on the Island of Hawaii, where seismic activity is part of daily risk planning rather than a rare exception.

USGS says more than 30 magnitude-6.0-or-greater earthquakes have struck the Hawaiian Islands since 1868, a reminder that strong quakes are part of the state’s hazard landscape. For emergency managers and coastal communities, the distinction matters: a serious earthquake does not automatically mean a tsunami threat, and the alert system is designed to separate ground shaking from immediate coastal danger.
