Satellite measurements on July 18 show continued SO₂ emissions from the erupting fissure in #Iceland and dispersion of SO₂ over #Greenland and the #Arctic Ocean.

Dispersion of #volcanic SO₂ from the latest #eruption on #Iceland's #Reykjanes peninsula (July 16), measured by the Sentinel-5P TROPOMI satellite instrument. SO₂ emissions have spread into north and west Iceland, impacting air quality (Icelandic Met Office). @esa.int

Satellite imagery of nighttime lights using the NOAA-20/VIIRS Day/Night Band ('visible image at night') shows areas of Spain and Portugal still affected by power outages overnight on April 28-29. Images from NASA Worldview. @thenasaearth.bsky.social @noaa.gov

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.

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 🧪

#Volcanic SO₂ plume from #Kanlaon #volcano captured and entrained by Super Typhoon #Man-yi (#Pepito) during its passage through the #Philippines. Data from the #geostationary GK-2B GEMS instrument.

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

Longer sequence of hourly #GEMS data (daytime only) showing SO₂ emissions from the June 3 #Kanlaon #eruption. On June 5, the upper tropospheric SO₂ cloud was moving west over #SriLanka and S. #India, whilst SO₂ at lower altitudes is dispersing over the southern #Philippines.

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.

Consecutive orbits of #TROPOMI data on May 30 show ongoing SO₂ emissions from the Sundhnúksgíga #eruption. The SO₂ plume emitted on May 29 is now drifting towards NW #Scotland & SO₂ columns in this cloud remain quite high (~200 DU). Might create some visible haze. @EIlyinskaya

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
