M5.6 Shallow Earthquake Recorded Near 174 km NW of Port-Olry, Vanuatu
USGS Week reports M5.6 near 174 km NW of Port-Olry, Vanuatu, with a 10.0 km catalog depth.
The event began at Wed, 28 Oct 2026 02:59:48 GMT. USGS Week reports magnitude 5.6, 10.0 km catalog depth, and coordinates -14.069, 165.800.
The catalog location label is 174 km NW of Port-Olry, Vanuatu; no separate nearest-city field was supplied with this solution. By catalog depth, this is a shallow event. The magnitude-derived energy estimate is 1.58e+13 joules, or about 3,788 tons of TNT equivalent; that calculation describes source energy, not local damage.
The current catalog entry does not include a public felt-report count. Other attached observation fields include catalog significance score 482. No official casualty or damage statement is attached to the normalized event evidence.
The USGS Week catalog currently marks the solution as reviewed. No station-count, phase-count, residual, gap, or uncertainty fields were supplied in the normalized record. Other agency solutions retained for this same origin are GEOFON GFZ M6.1. These are alternate reported solutions, not additional earthquakes.
The provider record does not carry a tsunami flag at publication time. Magnitude, depth, and location can change as monitoring networks add observations and review the solution.
