Is Io-Torishima erupting right now?
There is no open NASA EONET event for Io-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 1664. 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 Io-Torishima
USGS has no earthquake within 50 km of Io-Torishima 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 Io-Torishima
Io-Torishima is a complex volcano in Ryukyu Is, Japan, rising to 212 m (696 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 Uruma, about 171 km SSW of the summit; 4 other cities lie within 250 km.
- Uruma (171 km)
- Okinawa (177 km)
- Ginowan (186 km)
- Urasoe (187 km)
- Naha (193 km)
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Shanghai Pudong, 719 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 Suwanosejima, 243 km away.
