Earthquakes in Vanuatu Region

USGS

Right now

The most recent data we hold from USGS arrived 35 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

Reported by USGS today.

It is the only one we have recorded within 20 km of this point since 25 September 2026.

What the source measured

USGS reported: Vanuatu region

USGS recorded magnitude 5.3 at a depth of 24 km.

How we know

4 recorded sources include USGS; independence is not established by this count.

Our own score for this event is 18 out of 100.

This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.

Computed under scoring rules v5. Rows carrying other versions were judged by different rules and are not directly comparable.

Physical priority index · v5. Heuristic priority, not calibrated probability, predictive accuracy or damage. The legacy data-support index combines assigned source support and field availability. Urban PEI is distance-weighted and does not count unique people; zero does not establish that nobody is present. Model cards.

Safety Information

If you feel shaking: Drop, Cover, and Hold On. Move away from windows, heavy objects, and exterior walls. After shaking stops, check for injuries and structural damage. Be prepared for aftershocks, which can occur minutes to months after the mainshock. Follow instructions from local emergency management authorities.

Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
