GEOFON GFZ reports M5.0 near Mariana Islands, with a 237.6 km catalog depth.

Published 2026-10-21T06:29:50.394Z

The event began at Tue, 20 Oct 2026 07:09:08 GMT. GEOFON GFZ reports magnitude 5.0, 237.6 km catalog depth, and coordinates 18.900, 145.520.

The catalog location label is Mariana Islands; 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 2.14e+12 joules, or about 511 tons of TNT equivalent; that calculation describes source energy, not local damage.

The current catalog entry does not include a public felt-report count. No separate intensity or catalog-significance detail is available from this provider record. No official casualty or damage statement is attached to the normalized event evidence.

GEOFON GFZ has not supplied a review status in the normalized record. 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 EMSC Global M4.9. 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.
