Is Mount Spurr erupting right now?
There is no open NASA EONET event for Mount Spurr right now. NOAA NCEI dates its most recent eruption to 1964 or later, and the last eruption in its significant-eruption database was in 1992. 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 Mount Spurr
USGS located 161 earthquakes within 50 km of Mount Spurr in the past 30 days, 43 of them in the last week. The largest was M2.9 on Oct 5, 2026, 24 km ENE of the summit at 93 km depth.
68 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 Mount Spurr
Mount Spurr is a stratovolcano in Alaska-SW, United States, rising to 3,374 m (11,070 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 126 km E of the summit.

Flights and volcanic ash
1 major airport is within 400 km; the closest is Ted Stevens Anchorage (ANC), 121 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) | 121 km | E |
