📢 Update on the 2022 #Fagradalsfjall #eruption on #reykjanes:
Except for continuous degassing, no activity was observed at the vents since 6am of 21/08/2022. It is likely that eruption from the vents is over. But, any of 2-3 scenarios could be unfolding. More info 👇(1/7)

The eruption lingered on throughout the night of 20/08/2022. The glow from the northern vent, and from the lava creek flowing out of the lava pond to the SE, lit up the gas plume that rose from the crater. The glow from the lava creek diminished during the night. (2/7)
The northern vent maintained a glow until daybreak yesterday (i.e., until 4am on 21/08/2022). At around 5am, this vent ejected glowing magma blebs (spatter bombs) in several discrete explosions, over a period of 15 minutes. The bombs breached the crater rim (photo). (3/7) 
First on our list of master's student members is Jacqueline Grech Licari (@GrechLicari). She is a Maltese student specialising in physical volcanology and geochemistry at the Faculty of Earth Sciences at @Haskoli_Islands and is graduating in October (1/4)
@GrechLicari obtained a B.Sc. in Earth Systems from the @UMmalta in 2018, where she evaluated #tsunami impacts on the NE coast of Malta. She joined us in 2019 after conducting #scicomm at @EsploraMT (2/4)
Her thesis investigated shallow conduit processes, volatile behaviour & transport-deposition mechanisms of the #explosive phases of the 1211 Yngri Stampar #eruption in #Reykjanes. She was supervised by @ThorvaldurThor4, @volcano_will, Prof. Enikö Balí & Prof. Bruce Houghton (3/4)
🌋 Vamos a tratar de resolver una duda volcánica: ¿Por qué vemos en la erupción de #Islandia de la fisura de #Fagradalsfjall gente muy próxima a la lava y en la última erupción de #LaPalma se puso un perímetro de distancia de seguridad mucho mayor?

Podríamos dar 3⃣ claves principales:
👉 explosividad de la erupción
👉 relieve de la zona
👉 cercanía real de los turistas a la erupción

👉 cercanía real de los turistas a la erupción
🌋 Ninguna erupción es igual que otra y aunque en este caso la erupción de #Islandia es de origen fisural y con bastantes similitudes a la erupción en #CumbreVieja en 2021, su índice de explosividad parece que va a ser sensiblemente inferior al de la isla de #LaPalma.
A je to tady vážené a vážení, máme novou sopečnou erupci na Islandu v oblasti poloostrova #Reykjanes!
Tady je odkaz na živý stream, kde můžete průběh erupce sledovat.
Přidávám odkaz na dvojici starších vláken, kde začátek otřesů a průběh toho, co se tam v posledních dnech dělo, shrnuji.
Otřesy na poloostrově Reykjanes v oblasti sopky #Fagradalsfjall se odehrávají již jen v hloubce 1 (!!!) kilometru
Islandská @Vedurstofan tak dnes vydala varování, že šance na erupci během následujících dní/týdnů významně narostla a je dost vysoká.

2/x Moje islandština není nic moc, takže jedu zprávu s pomocí Google translate... Nicméně z ní chápu, že množství magmatu deroucí se žílou k povrchu je přibližně dvojnásobné oproti minule (což neznamená množství magmatu, které se dostane nakonec na povrch!)
3/x Deformace povrchu a seismická činnost se zdá v posledních hodinách zpomalovat, což bylo přesně pozorováno i minule před tím, než došlo k erupci.

You can watch Iceland doing its volcano thing live. Love this! ruv.is/frett/2021/03/…
The helicopter on the lower edge of the screen just took off and flew away, but the people are still there at the bottom end of the lava flow.
An error that spellcheck won't catch.
(1) As a hurricane watcher (amateur, from behind a screen) I take an interest in other disaster types like earthquake, tsunami, & volcano.
International media coverage of the #Fagradalsfjall eruption in Iceland misses the mark a bit. Here's why.

(2) I see this phenomenon all the time, whenever New Zealand has an earthquake, tsunami or volcanic eruption.
Few in the media are trained in the responsible reporting of such disasters. They aim for clicks & ratings with little regard for public safety (anywhere.)

(3) Emergency Management Agencies (EMAs) usually issue media guidance & I've read such materials produced by the USA's FEMA.gov (the largest EMA in the world.) Unfortunately FEMA's website redesign makes it hard to find them now, but I'll add links below later on.
Potential #eruption started in #Fagradalsfjall - being investigated after reports of bright lights from the area #Reykjanes #Iceland #volcano #icerupt
Web cams show the bright light from the area. The Coast Guard helicopter being dispatched.

It has been confirmed by @krjonsdottir at @Vedurstofan that a volcanic eruption has started in #Fagradalsfjall on #Reykjanes peninsula in #Iceland - photo from @Vikurfrettir
Heads up: Iceland has been monitoring #volcano unrest at #Reykjanes Peninsula. #Aviation color code orange due to quakes & indications of shallow magma dike. If an eruption occurs, ash hazard may affect North Atlantic air #travel. en.vedur.is/weather/aviati… #geology #weather
"Suspense in Iceland as dormant volcanic zone shows signs of life" by @physorg_com - volcanologists say a #Reykjanes eruption would likely be more lava than ash; not expecting repeat of 2010 Eyjafjallajokull #aviation #travel disruption phys.org/news/2021-03-s… #volcano #geology
"Sleeping Giant: Earthquakes And Volcanoes In #Reykjanes" by @rvkgrapevine - volcanologists describe how the peninsula's eruption history shapes expectations of possible volcanic activity to mostly lava flows, not explosions/ash grapevine.is/mag/feature/20… #Iceland #volcano #geology
Strong signs of a potential #volcano #eruption near #Keilir on #Reykjanes peninsula. Scientists reporting #earthquake patterns that are similar to the start of an eruption. Eruption likely to start within the next few hours.
The ICAO airport code for @kefairport and #Reykjavik airport have been raised to Orange - which indicates a high likelihood of imminent eruption. Rescue teams are being put on standby. Coast Guard @gaeslan helicopter to fly over the area shortly. Press briefing scheduled for 1600
This potential eruption is not expected to cause any damage to infrastructure and towns/cities according to @almannavarnir. The eruption has not yet started and is far away from habited places.
Op het schiereiland Reykjanes wordt hard gewerkt aan de mid-oceanische rug. Dit soort aardbevingen gaan vaak gepaard met een magma-injectie in de korst, die ongeveer 10 km dik is onder dit deel van #IJsland (35 km onder Nederland. Soms leidt dat tot een spleetuitbarsting.
De aardbevingszwermen op het schiereiland Reykjanes, Z.W. #IJsland, blijven toenemen. Wie weet zit er wel een spleetuitbarsting in.
Mooi om te zien hoe de aardbevingen schommelen rond de as van van het Krýsuvík systeem. Er wordt daar flink wat magma geïnjecteerd.
