Is Unnamed erupting right now?
There is no open NASA EONET event for Unnamed 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 Unnamed
USGS located 12 earthquakes within 50 km of Unnamed in the past 30 days, 5 of them in the last week. The largest was M3.5 on Oct 3, 2026, 32 km SSW of the summit at 35 km depth.
2 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 Unnamed
Unnamed is a submarine volcano in Aleutian Is, United States, rising to 0 m (0 ft). NOAA NCEI classes its eruptive history as "Hydrophonic".
Submarine volcanoes erupt under the sea; shallow ones can produce steam explosions, pumice rafts and discoloured water.
The volcano is remote: the nearest city in our list is Anchorage, 1755 km away.
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Ted Stevens Anchorage, 1748 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.
Other volcanoes in United States
United States has 58 volcanoes on this site that erupted since 1900 or are active now, 2 of them with an open NASA activity report today. The closest other one is Atka Volcanic Complex, 57 km away.
