Is Ontakesan erupting right now?

There is no open NASA EONET event for Ontakesan right now. NOAA NCEI dates its most recent eruption to 1964 or later, and the last eruption in its significant-eruption database was in 2014. 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 Ontakesan

USGS has no earthquake within 50 km of Ontakesan 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 Ontakesan

Ontakesan is a complex volcano in Honshu-Japan, Japan, rising to 3,067 m (10,063 ft). NOAA NCEI classes its eruptive history as "Historical".

Complex volcanoes have several vents or overlapping cones, so activity can shift between craters.

The nearest large town is Iida, about 52 km SE of the summit; 5 other cities lie within 250 km.

Flights and volcanic ash

3 major airports are within 400 km; the closest is Haneda (HND), 211 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.
