New submarine #volcanic #eruption in the Central Bismarck Sea (Papua New Guinea) at ~3ºS, 148ºE. Previous activity reported in this region in 1972. Plume breached ocean surface on May 9 at ~01:00 UTC; w/ small pumice raft. Animation shows MODIS/VIIRS imagery & thermal IR hotspots from May 9-12.

Four years since #Hunga #volcano (Tonga) unleashed one of the most explosive volcanic #eruptions ever observed, providing a new paradigm of submarine volcanism. Read all about the atmospheric impacts of the 2022 Hunga eruption in a new open-access report: juser.fz-juelich.de/record/1049154

An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.

The world's youngest mountain glacier - Crater Glacier at Mount St. Helens #volcano (WA, USA) - formed in 1996 in the amphitheater produced by the May 1980 eruption. The glacier flows around lava domes erupted in 1980-86 and 2004-08. Photos taken in 2023. #WorldGlacierDay 🧪🌋

🧪🛰️ My colleague @simoncarn.bsky.social and I were consulted for this note by @avoiland.bsky.social to comment on volcanoes and clouds in the South Atlantic. A nice place to study aerosol-cloud interactions! (and other things of course) earthobservatory.nasa.gov/images/15404...

Swirling Skies and Melting Icebergs

The remote South Sandwich Islands can disrupt passing clouds in ways that shed alternating rows of cloud spirals.

When Spurr last erupted in 1992, volcanic ash & gas clouds (a potential aviation hazard) drifted south over the Pacific NW & Upper Midwest. A fully functional USGS & NOAA is needed to monitor such events & mitigate their impacts. NASA/NOAA satellite data also critical for tracking volcanic clouds.

The closest active volcano to Anchorage — Mount Spurr — is now expected to erupt within the next few weeks. Would be a great time to have a fully-staffed NOAA to help navigate the impacts of this likely disaster. www.adn.com/alaska-news/...

Some folks have asked, given recent news, “how do I show my friends/family the impact of NSF?” We have some easy Fact Sheets for you! Here’s a brief thread about this website: new.nsf.gov/about/fact-s... which hosts a ton of useful one-pagers.

A reminder: If you need to know about volcanic activity in the United States and are concerned that you might not be able to reach USGS websites at some point, PLEASE make sure you sign up for our volcano notification Service: volcanoes.usgs.gov/vns3/ It is a straight-to-email messaging system. 🌋🧪⚒️

Satellite imagery from @planet.com shows increased steaming in the summit caldera of Fentale volcano (Ethiopia) in the last week. Emissions appear confined to topographic lows - perhaps a meteorological effect (temperature inversion?). @davidmpyle.bsky.social @volckaren.bsky.social 🧪

No insurer will write a policy for global cooling triggered by a massive 🌋eruption. But we shouldn't ignore a risk just because it's uninsurable. In this comment led by Markus Stoffel, we argue the risk industry ought to think more seriously about 'Tambora 2.0'. www.nature.com/articles/d41...

The next massive volcano eruption will cause climate chaos — and we are unprepared

Volcanic activity will be experienced differently in a warmer world. Researchers need to understand these risks and how they could spiral.

Another batch of #volcanic SO₂ en route to the #UK/#Ireland, courtesy of the latest #eruption on #Iceland's #Reykjanes peninsula. Might cause some local #AirQuality impacts in the coming days. @eddy_weather @ScottishEPA SO₂ data: @NOAA/@NASA @JPSSProgram #NOAA20-#OMPS

The first #lava flows since 1974 on #Kīlauea's Southwest rift zone, imaged by @planet on June 3 at 20:09 UTC (10:09 HST), shortly before the #eruption paused. #Hawaii @USGSVolcanoes @USGS @Volcanoes_NPS

The largest #eruption on record of #Kanlaon/#Canlaon #volcano (#Philippines) on June 3 produced an upper tropospheric SO₂ cloud (~0.05 Tg SO₂), seen here from #geostationary orbit by #SouthKorea's UV #GK2B #GEMS sensor. @phivolcs_dost @News5PH @nababaha

First #Sentinel5P #TROPOMI overpass ~1.3 hours after the onset of today's #eruption on #Iceland's #Reykjanes peninsula shows very high SO₂ column amounts in plume spreading SE. Est. SO₂ emission rate is ~1400 kg/s (~120,000 tons/day). @Vedurstofan @CopernicusEU @rockhardIES

SO₂ emissions from the April 16 #eruption of #Ruang #volcano (#Indonesia) measured with hourly cadence by #SouthKorea's #geostationary UV GK-2B #GEMS sensor. Relatively low SO₂ amounts detected so far. @PVMBG_ @id_magma @andrewcraigtupp

The latest #eruption in #Iceland has produced the largest #volcanic SO₂ cloud measured to date in the 2023-24 #Reykjanes Fires, consistent with reports that it is the most intense episode so far. Data: @CopernicusEU #Sentinel5P #TROPOMI. @Vedurstofan @rockhardIES @Alberto_Carac

As sunlight gradually returns to high northern latitudes, so does UV satellite monitoring of #volcanic SO₂ emissions from #Iceland. #Sentinel5P #TROPOMI detected SO₂ from today's #eruption on the #Reykjanes peninsula drifting over the N. Atlantic.
