Is Izu-Torishima erupting right now?
There is no open NASA EONET event for Izu-Torishima right now. NOAA NCEI dates its most recent eruption to 1964 or later, and the last eruption in its significant-eruption database was in 1939. 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 Izu-Torishima
USGS located 1 earthquake within 50 km of Izu-Torishima in the past 30 days, 0 of them in the last week. The largest was M4.7 on Oct 8, 2026, 44 km NE of the summit at 47 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.

About Izu-Torishima
Izu-Torishima is a stratovolcano in Izu Is-Japan, Japan, rising to 394 m (1,293 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 volcano is remote: the nearest city in our list is Ōyama, Shizuoka, 498 km away.
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Haneda, 565 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.
Other volcanoes in Japan
Japan has 52 volcanoes on this site that erupted since 1900 or are active now, 3 of them with an open NASA activity report today. The closest other one is Sofugan, 77 km away.
