Is San Jose erupting right now?
There is no open NASA EONET event for San Jose 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 San Jose
USGS located 1 earthquake within 50 km of San Jose in the past 30 days, 0 of them in the last week. The largest was M4.3 on Oct 12, 2026, 35 km WNW of the summit at 107 km depth.
0 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.
| Time (UTC) | Magnitude | Distance | Depth | Location |

About San Jose
San Jose is a stratovolcano in Chile-C, Argentina, rising to 6,070 m (19,916 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 Puente Alto, about 66 km WNW of the summit; 5 other cities lie within 250 km.
- Puente Alto (66 km) earthquakes nearby
- Peñalolén (69 km) earthquakes nearby
- La Pintana (72 km) earthquakes nearby
- San Bernardo (78 km) earthquakes nearby
- Santiago (79 km) earthquakes nearby
- Lo Prado (86 km) earthquakes nearby
Flights and volcanic ash
1 major airport is within 400 km; the closest is Santiago (SCL), 94 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.
