Three months later the #Geldingadalir 2021 eruption, #Iceland behaved completely different. The lava effusion is now not driven from gas accumulation in a shallow reservoir beneath an open vent but the vent is closed between effusion periods.

My first paper is published! 🌋🇮🇸🥳 if you want to learn more about lava lake spattering and seismic tremor during the 2021 Geldingadalir eruption, check out the paper.🌋🇮🇸 #Geldingadalir #iceland #volcano

New paper by Z Zali, together with institute members E Eibl, M Ohrnberger and F Cotton from GFZ, on the 2021 #Geldingadalir #eruption on #Iceland, published in Comm Earth & Environment. nature.com/articles/s43... /mht #geophysics #volcanology
The nocturnal glow of fresh #lava on #Iceland's #Reykjanes peninsula marks the onset of the #Geldingadalir #eruption at #Fagradalsfjall in March 2021.

Lamp-light and #lava-light; last night at #Geldingadalir. Images from the @mblfrettir webcam in Nátthagi, #Fagradalsfjall. #Iceland #volcano
After a short repose, #lava once again lights up the night at #Geldingadalir (#Fagradalsfjall #volcano) in #Iceland.
@NASA @JPSSProgram Suomi/NPP #VIIRS Day/Night band imagery from Sept 2-12. @NASAEarth @NASAEarthData
The #eruption will be televised. It has to be said, @mblfrettir and @RUVfrettir are really spoiling us with the webcams at #Geldingadalir, #Iceland. A front-row seat to active basaltic volcanism.
Recent expansion of the #lava flow field at #Geldingadalir captured in clear @planetlabs PlanetScope images on May 3 & 9. I guess the dark areas that appear mostly NW & W of the main vent are burn scars from wildfires ignited by ejecta. @rsimmon @krjonsdottir @RagnarHeidar
The UK travel #greenlist is perfect for a memorable #Atlantic #volcano vacation. Island-hop through the active #SouthSandwichIslands, then visit #TristandaCunha & #AscensionIsland before finishing up in #Iceland to see the #Geldingadalir #eruption. Boat recommended. @SimonCalder
After a high #lava fountain at ~05:40 am on May 5 (image from @RUVfrettir webcam), #Sentinel5P #Tropomi detected some of the largest SO₂ emissions observed to date in the #Geldingadalir #eruption. #Reykjanes @RagnarHeidar @gislio @EIlyinskaya
Discrete puffs of gas from periodic #lava fountains at #Geldingadalir are visible in @NASA Aqua/MODIS 🛰️imagery on May 4. Downwind they merge into a plume extending ~500 km from #Iceland based on #Sentinel5P #Tropomi SO₂ data. @CopernicusEU @NASAEarth @Vedurstofan @krjonsdottir
#Volcanic SO₂ emissions from #Geldingadalir dispersing over #Iceland's Langjökull & Hofsjökull icecaps on Mar 24. On a larger scale, this is how some #eruptions become preserved in the cryospheric record. Data: @CopernicusEU #Sentinel5P #Tropomi. @THERA_4ever #Geldingardalsgos
Perhaps the hottest spot on #Iceland's #Reykjanes peninsula in about 800 years. #Fagradalsfjall #Geldingardalsgos #Geldingadalir #eruption #icelanderuption
