Is Central Bismarck Sea erupting right now?
NASA's Earth Observatory Natural Event Tracker (EONET) has an open volcanic event for Central Bismarck Sea, last updated May 28, 2026 (151 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 Central Bismarck Sea
USGS has no earthquake within 50 km of Central Bismarck Sea 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 Central Bismarck Sea
Central Bismarck Sea is a submarine volcano in Admiralty Is-SW Paci, United States, rising to -1,300 m (-4,265 ft). NOAA NCEI classes its eruptive history as "Hydrophonic".
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 Port Moresby, 720 km away.
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Brisbane, 2767 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 United States
United States has 58 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 St. Andrew Strait, 87 km away.
