Is Ukinrek Maars erupting right now?
There is no open NASA EONET event for Ukinrek Maars right now. NOAA NCEI dates its most recent eruption to 1964 or later. 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 Ukinrek Maars
USGS located 43 earthquakes within 50 km of Ukinrek Maars in the past 30 days, 1 of them in the last week. The largest was M3.4 on Oct 5, 2026, 45 km ESE of the summit at 5 km depth.
15 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.

Flights and volcanic ash
No major hub airport is within 400 km (the closest is Ted Stevens Anchorage, 522 km away), but ash clouds from explosive eruptions can drift for thousands of kilometres along flight routes.
Volcanic Ash Advisory Centres (VAACs) issue the official ash advisories that airlines and air traffic control follow.
