Is Semeru erupting right now?

NASA's Earth Observatory Natural Event Tracker (EONET) has an open volcanic event for Semeru, last updated Jan 18, 2020 (2473 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.

NASA FIRMS shows 1 thermal hot spot within 10 km of the summit in the latest VIIRS satellite passes (strongest 2.8 MW fire radiative power). Hot spots on a volcano can be lava, a glowing vent or ordinary vegetation fires; satellites cannot tell them apart on their own.

Earthquakes near Semeru

USGS has no earthquake within 50 km of Semeru 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 Semeru

Semeru is a stratovolcano in Java, Indonesia, rising to 3,657 m (11,999 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 Lumajang, about 33 km E of the summit; 5 other cities lie within 250 km.

Flights and volcanic ash

No major hub airport is within 400 km (the closest is Soekarno–Hatta, 726 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 Indonesia

Indonesia has 66 volcanoes on this site that erupted since 1900 or are active now, 6 of them with an open NASA activity report today. The closest other one is Tengger Caldera, 19 km away.
