Is Uzon erupting right now?
NASA's Earth Observatory Natural Event Tracker (EONET) has an open volcanic event for Uzon, last updated Aug 25, 2025 (427 days ago). EONET opens an event when agencies such as the Smithsonian Global Volcanism Program report eruptive activity or unrest, and closes it when activity ends.
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 Uzon
USGS has no earthquake within 50 km of Uzon 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 Uzon
Uzon is a caldera in Kamchatka, Russia, rising to 1,617 m (5,305 ft). NOAA NCEI classes its eruptive history as "Radiocarbon".
A caldera is a large collapse depression left after a major eruption; activity can range from small steam blasts to rare, very large eruptions.
The nearest large town is Petropavlovsk-Kamchatsky, about 181 km SSW of the summit.

Flights and volcanic ash
No major hub airport is within 400 km (the closest is Narita, 2568 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 Russia
Russia has 45 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 Maly Semyachik, 44 km away.
