Is Iliamna erupting right now?
There is no open NASA EONET event for Iliamna right now. NOAA NCEI dates its most recent eruption to 1900–1963. Volcano observatories can raise alert levels before an eruption starts, so check the national observatory for the current alert level.
No satellite thermal hot spot was detected within 10 km of the summit in the latest NASA FIRMS data, so there is no sign of lava at the surface large enough for VIIRS to see (clouds can hide it).
Earthquakes near Iliamna
USGS located 300 earthquakes within 50 km of Iliamna in the past 30 days, 69 of them in the last week. The largest was M3.5 on Oct 19, 2026, 24 km SSW of the summit at 126 km depth.
171 of them were shallower than 10 km. Swarms of shallow quakes can mean magma or gas is moving, but most swarms end without an eruption; observatories combine them with ground deformation and gas data.

About Iliamna
Iliamna is a stratovolcano in Alaska-SW, United States, rising to 3,053 m (10,017 ft). NOAA NCEI classes its eruptive history as "Historical".
Stratovolcanoes are steep cones built from alternating lava and ash layers; their eruptions are often explosive, with ash columns that can reach cruising altitude.
The nearest large town is Anchorage, about 218 km NE of the summit.

Flights and volcanic ash
1 major airport is within 400 km; the closest is Ted Stevens Anchorage (ANC), 211 km away. Volcanic ash melts in jet engines, so an explosive eruption can close airspace and cancel flights even far downwind.
Volcanic Ash Advisory Centres (VAACs) issue the official ash advisories that airlines and air traffic control follow.
| Airport | Distance | Direction |
|---|---|---|
| Ted Stevens Anchorage (ANC) | 211 km | NE |
Other volcanoes in United States
