Is Yellowstone erupting right now?
There is no open NASA EONET event for Yellowstone right now. NOAA NCEI dates its most recent eruption to b.c. (holocene), and the last eruption in its significant-eruption database was in 2016. 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 Yellowstone
USGS located 59 earthquakes within 50 km of Yellowstone in the past 30 days, 16 of them in the last week. The largest was M1.9 on Oct 4, 2026, 26 km SSE of the summit at 12 km depth.
43 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 Yellowstone
Yellowstone is a caldera in Wyoming, United States, rising to 2,805 m (9,203 ft). NOAA NCEI classes its eruptive history as "Tephrochronology".
A caldera is a large collapse depression left after a major eruption; activity can range from small steam blasts to rare, very large eruptions.
The nearest large town is Rexburg, about 112 km SW of the summit; 5 other cities lie within 250 km.
- Rexburg (112 km) earthquakes nearby
- Bozeman (142 km) earthquakes nearby
- Idaho Falls (153 km)
- Pocatello (225 km)
- Billings (227 km)
- Butte (228 km)
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Denver International, 709 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.
