M5.9 Shallow Earthquake Recorded Near Tonga [Sea]
INGV Italy reports M5.9 near Tonga [Sea], with a 4.7 km catalog depth.
The event began at Wed, 23 Sep 2026 14:41:02 GMT. INGV Italy reports magnitude 5.9, 4.7 km catalog depth, and coordinates -14.527, -174.970.
The catalog location label is Tonga [Sea]; 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. 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.
INGV Italy 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 GEOFON GFZ M5.5. 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.
