The event began at Sun, 20 Sep 2026 12:45:53 GMT. USGS Week reports magnitude 5.4, 116.0 km catalog depth, and coordinates -5.771, 146.204.

The catalog location label is 68 km NNE of Kainantu, Papua New Guinea; no separate nearest-city field was supplied with this solution. By catalog depth, this is an intermediate-depth event. The magnitude-derived energy estimate is 7.94e+12 joules, or about 1,898 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 449. 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 M5.8. 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.
