Is Lassen Volcanic Center erupting right now?
There is no open NASA EONET event for Lassen Volcanic Center 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 Lassen Volcanic Center
USGS located 11 earthquakes within 50 km of Lassen Volcanic Center in the past 30 days, 0 of them in the last week. The largest was M2.3 on Oct 13, 2026, 49 km SSE of the summit at 10 km depth.
11 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 Lassen Volcanic Center
Lassen Volcanic Center is a stratovolcano in California, United States, rising to 3,187 m (10,457 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 Redding, about 75 km W of the summit; 5 other cities lie within 250 km.
- Redding (75 km) earthquakes nearby
- Chico (89 km) earthquakes nearby
- Yuba City (151 km)
- Lincoln, CA (179 km)
- Reno (180 km)
- Sparks (183 km)
Flights and volcanic ash
1 major airport is within 400 km; the closest is San Francisco International (SFO), 328 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 |
|---|---|---|
| San Francisco International (SFO) | 328 km | SSW |
