How we know
One source: USGS Volcano Hazards Program. Not yet confirmed by a second, independent source.
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.
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.

Safety information
What to do near an active volcano
Three things first, then what to do before, during and after an eruption. From FEMA, the US Geological Survey and IVHHN, the volcanic health network.
For this reportVolcanic activity · United States
Follow the evacuation orders
Leave when authorities say so, by the routes they give. Lava, ash and mudflows can reach far down the valleys.
Ready.govIndoors when ash falls
Close windows and doors, cover vents. Outside, wear a well-fitting mask (an N95/FFP2) and goggles.
Ready.gov · IVHHNKeep away from valleys
Stay out of river valleys and low ground downstream of the volcano: mudflows (lahars) run fast along them.

Before, during, after. Here it is still “during”.
Before · When the volcano is restless
Know the alert levels
Learn the volcano’s alert levels and follow its observatory.
Masks and goggles
Keep N95/FFP2 masks and goggles for everyone at home.
Plan to leave and to stay
An evacuation route, and a plan to stay sealed indoors during ashfall.
Ask your doctor
If you have asthma or another breathing condition, ask what to do in ash.
Ready.gov (FEMA)
During · During an eruption
Leave if told
Do not wait to see the eruption.
Do not drive in heavy ash
It cuts visibility to nothing and clogs engines.
Cover up
Long sleeves and trousers; a mask and goggles if you must go out.
Keep children and pets in
Ash irritates eyes and lungs.
Ready.gov (FEMA)
After · When the ash settles
Wait for the authorities
Leave your shelter when they say it is safe.
Clear ash carefully
Wet it lightly first, wear a mask; ash is heavy and slippery on roofs, so do not climb unless trained.
Protect the water
Cover water tanks; do not drink water that ash has fallen into.

Questions people ask
Is volcanic ash dangerous to breathe?
It can be: it is made of tiny sharp particles of rock and glass. Stay indoors, and wear a well-fitting N95/FFP2 mask outside. Source: IVHHN, Ready.gov (FEMA).
What is a lahar?
A mudflow of volcanic debris and water that runs down valleys, fast and far. Keep away from river valleys near an active volcano. Source: US Geological Survey.
Can I drive in ashfall?
Avoid it: visibility drops and ash damages engines. If you must, drive slowly with lights on. Source: Ready.gov (FEMA).
