Update: the reporting agency changed this event's magnitude from M5.8 to M5.9. The current value is shown throughout this brief; the earlier value is retained here as revision history.

The event began at Sun, 25 Oct 2026 11:25:57 GMT. USGS Week reports magnitude 5.9, 7.0 km catalog depth, and coordinates 32.462, 94.053.

The catalog location label is 218 km ENE of Nagqu, China; no separate nearest-city field was supplied with this solution. By catalog depth, this is a shallow event. The magnitude-derived energy estimate is 4.47e+13 joules, or about 10,676 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 650. 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. 1 alternate network solution is retained for comparison.

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.
