Right now
The most recent data we hold from USGS arrived 59 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
One other detection within 20 km in the last 24 hours, <1 km from here.
Reported by USGS 105 days ago.
It is the 15th strongest of the 203 detections recorded within 20 km of this point since 7 March 2026. Another comparable one was recorded here earlier the same day. 15 more were recorded here in the fortnight before it.

How we know
One source: USGS. Not yet confirmed by a second, independent source.
Our own score for this event is 20 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 v1. Rows carrying other versions were judged by different rules and are not directly comparable.

Safety Information
During volcanic activity: follow evacuation orders from authorities. Volcanic ash can damage lungs — wear N95 masks or wet cloth over nose and mouth. Stay indoors during ashfall, close windows, and avoid driving. Lahars and pyroclastic flows can travel at high speeds — stay away from valleys and river channels near the volcano.
Series begins 8 March 2026 for live collection; the monthly chart also counts backfilled detections from 10 February 2024. Collection gap: 14-26 August 2026.
