Is Ranakah erupting right now?
There is no open NASA EONET event for Ranakah right now. NOAA NCEI dates its most recent eruption to 1964 or later. 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 Ranakah
USGS located 2 earthquakes within 50 km of Ranakah in the past 30 days, 0 of them in the last week. The largest was M5.0 on Oct 4, 2026, 49 km NNW of the summit at 10 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 Ranakah
Ranakah is a lava dome in Lesser Sunda Is, Indonesia, rising to 2,288 m (7,507 ft). NOAA NCEI classes its eruptive history as "Historical".
Lava domes grow from thick, sticky lava; collapsing domes can send fast pyroclastic flows down the slopes.
The nearest large town is Labuan Bajo, about 72 km WNW of the summit; 1 other city lie within 250 km.

Flights and volcanic ash
No major hub airport is within 400 km (the closest is Soekarno–Hatta, 1555 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, 7 of them with an open NASA activity report today. The closest other one is Inielika, 51 km away.
