Is Chokaisan erupting right now?
There is no open NASA EONET event for Chokaisan right now. NOAA NCEI dates its most recent eruption to 1964 or later, and the last eruption in its significant-eruption database was in 1801. 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 Chokaisan
USGS has no earthquake within 50 km of Chokaisan in the past 30 days. Outside the United States USGS mainly lists quakes above about M4, so small volcanic tremors recorded by the local observatory will not appear here.
About Chokaisan
Chokaisan is a stratovolcano in Honshu-Japan, Japan, rising to 2,236 m (7,336 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 Sakata, about 26 km SW of the summit; 5 other cities lie within 250 km.

Flights and volcanic ash
2 major airports are within 400 km; the closest is Narita (NRT), 371 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 |
|---|---|---|
| Narita (NRT) | 371 km | S |
| Haneda (HND) | 395 km | S |
