A magnitude-6.7 earthquake struck southeast of the Loyalty Islands early Monday, but Hawaii emergency officials say there is no tsunami threat to the islands. The preliminary origin time was 4:46 a.m. HST on July 13, 2026, and the epicenter was near 23.0° South, 171.4° East. Seismologists recorded a shallow shock that triggered quick checks by Pacific tsunami authorities, yet no coastal evacuations were required in Hawai‘i.
Officials Relay PTWC Analysis
The Hawaii Emergency Management Agency posted a "NO Tsunami Threat" bulletin on its official X account and relayed initial analysis from the Pacific Tsunami Warning Center, according to Hawai‘i Emergency Management Agency. The PTWC's initial bulletin, hosted on the federal tsunami portal, classified the message as informational and said a destructive Pacific-wide tsunami was not expected, per Pacific Tsunami Warning Center. State civil defense officials reiterated that sirens and evacuations are ordered only when a credible threat is identified.
Where the Quake Hit and How Strong
Global seismic catalogs placed the epicenter at about 23.0° South, 171.4° East with a shallow hypocenter near 10 kilometers and an origin time of roughly 14:45 UTC, or about 4:45 a.m. HST. The U.S. Geological Survey magnitude was reported at 6.7, and international reporting quoting the agency noted no immediate reports of casualties or damage in the Loyalty Islands region, per Anadolu Agency. The Loyalty Islands archipelago sits along an active Pacific subduction zone where shallow earthquakes are a regular occurrence.
Why Hawai‘i Wasn't at Risk
The PTWC evaluates magnitude, mechanism, depth and distance when judging tsunami risk. Although a 6.7 quake can be hazardous locally, this event's geometry and distance meant the energy was unlikely to generate a destructive wave in Hawai‘i. Research on previous Loyalty Islands events shows the region most often produces local tsunamis that dissipate across the wider Pacific, according to a study in Earth and Space Science. Officials urged residents to rely on official agency channels for any change in status rather than social media rumors.
