Is Curacoa erupting right now?
There is no open NASA EONET event for Curacoa 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 Curacoa
USGS located 1 earthquake within 50 km of Curacoa in the past 30 days, 0 of them in the last week. The largest was M4.5 on Oct 10, 2026, 28 km NNW of the summit at 79 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 Curacoa
Curacoa is a submarine volcano in Tonga-SW Pacific, Tonga, rising to -33 m (-108 ft). NOAA NCEI classes its eruptive history as "Historical".
Submarine volcanoes erupt under the sea; shallow ones can produce steam explosions, pumice rafts and discoloured water.
The volcano is remote: the nearest city in our list is Suva, 886 km away.
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Auckland, 2637 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 Tonga
Tonga has 15 volcanoes on this site that erupted since 1900 or are active now. The closest other one is Tafahi, 26 km away.
