Is Lolobau erupting right now?
There is no open NASA EONET event for Lolobau right now. NOAA NCEI dates its most recent eruption to 1900–1963. 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 Lolobau
USGS located 1 earthquake within 50 km of Lolobau in the past 30 days, 0 of them in the last week. The largest was M4.6 on Oct 4, 2026, 32 km ESE of the summit at 162 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 Lolobau
Lolobau is a caldera in New Britain-SW Pac, Papua New Guinea, rising to 878 m (2,881 ft). NOAA NCEI classes its eruptive history as "Historical".
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 volcano is remote: the nearest city in our list is Port Moresby, 673 km away.
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Brisbane, 2507 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 Papua New Guinea
Papua New Guinea has 16 volcanoes on this site that erupted since 1900 or are active now, 1 of them with an open NASA activity report today. The closest other one is Ulawun, 24 km away.
