ELDGOS! - ERUPTION!

An eruption began on the Sundhnúkar volcanic lineament at ~22:17 in the evening of 18 December with a curtain of fire along a 4 km-long volcanic fissure, extending from north side of Hagafell in the south and just past Stóra Skógfell in the north, with magma discharge in the range of 100-200 m3/s and lava fountains rising as high as ~100 m.
The lava advances from the vents at rates close to 0.5-1 km per hour and the above values for the magma discharge-, along with the anticipated composition of the erupted magma, the current SO2 outgassing is on the order of 30 to 60 thousand tons per day or an order of magnitude more than in the 2021-23 eruptions. Sulfur dioxide reacts with atmospheric v***r to produce sulfuric aerosols / haze (= sulfuric acid droplets) and at this level in the atmosphere it takes about a day to convert half of th eSO2 mass into sulfuric aerosols, which are far more toxic than sulfur dioxide. If this eruption maintains this intensity, it will produce significant air pollution. The good news are that the wind is northwesterly and according to the forecast it will stay northerly for the next few days. Hence the eruption plume is likely to be blown away from inhabited areas.

Góða kvöldið

Eldgos hófst í Sundhnúkum um kl. 22:17 í kvöld (18 desember 2023) og er virknin á um 4 km langri sprungu sem liggur frá norðurhlíðum Hagafells og norður undir Stóra-Skógfell. Kvikustrókarnir virðast vera ansi öflugir og þeir hæstu um eða rétt yfir 100 metrunum og framleiðnin á bilinu 100 – 200 m3/s.
Þetta þýðir að hraunflæðið frá gígunum er að fara 0.5-1 km á klst. og miðað við ofangreinda framleiðni og væntanlega efnasamsetningu hraunkvikunnar þá er útstreymi brennisteinsdíoxíðs yfir gosstöðvunum einhversstaðar á bilinu 30-60 þúsund tonn á dag eða 10-falt meiri brennisteinslosun á tímaeiningu en var í gosunum 2021-23. Brennisteinsdíoxiðið hvarfast við vatnsgufu í andrúmsloftinu - myndar brennisteinssýru-agnir eða -móðu, sem er mun eitraðri en brennisteinsdíoxíð – og neðst í veðrahvolfinu er helmingunartími hvarfsins SO2 yfir í H2SO4 um það bil einn dagur. Þannig að gasútstreymið getur valdið verulegri, en tímabundinni mengun Sem betur fer þá er núverandi vindátt norðvestlæg og samkvæmt spánni á hún að vera norðlæg á næstu dögum. Vindurinn ætti því að halda gasmenguninni að mestu frá byggðum bólum.

-90% of the d**e solidified-

The greatest part of the d**e at Svartsengi has hardened. The likelihood of a volcanic eruption is decreasing and the inflation at Svartsengi has slowed down, says Magnús Tumi Guðmundsson, Prof. Geophysics, Univ. Iceland

The majority of the magma channel at Svartsengi has hardened. The likelihood of a volcanic eruption is decreasing and the land rising at Svartsengi has slowed down. Magnús Tumi Guðmundsson, professor of geophysics at the University of Iceland, says this to mbl.is.

Probability of an eruption is slowly decreasing. Seismic activity has decreased, unclear how long it will take the sill near Svartsengi to fill up again. However, there is still movement in the shallow d**e, including at Grindavík, we proceed with caution.

Líkur á eldgosi fara hægt minnkandi. Skjálftavirkni hefur minnkað og óljóst hve langan tíma það tekur kvikuhólfið nærri Svartsengi að fyllast að nýju. Enn er þó hreyfing á kvikuganginum sem liggur grunnt, meðal annars við Grindavík, og því full ástæða til að fara öllu me...

...Surtsey 60 today hurrahhh !...

The Surtsey eruption is among the longest eruptions to have occurred in Iceland in historical times. The first sign of an eruption came early in the morning of November 14, 1963, at a site approximately 18 km southwest of Heimaey, the largest of the Vestmannaeyjar (Westman Islands). The eruption is believed to have commenced a few days earlier on the sea floor, at a depth of 130 m.

11/11/2023

At 6 PM, a stationary meeting of scientists concluded at the Icelandic Meteorological Office and the University of Iceland, along with Civil Protection. They reviewed the interpretation of the latest data received at noon today. Models were developed based on artificial satellite images and GPS measurements. The models indicate a significant volcanic activity, with magma approaching the surface. The fissure extends about 15 km from Kálffellsheiði in the north, west of Grindavík, and into the sea towards the southwest. The magma is approximately 800 m deep, suggesting a significant risk of it reaching the surface. Based on this, there is a substantial likelihood of magma breaking through to the surface, with increased chances of it emerging on the seabed.

Following the interpretation of the latest data, the Icelandic Meteorological Office has recommended precautionary measures to Civil Protection, noting an increased risk of volcanic eruption since this morning, and stating that an eruption could occur at any time in the next few days.

Klukkan 18 lauk stöðufundi vísindamanna á Veðurstofu Íslands og Háskóla Íslands og Almannavarna þar sem farið var yfir túlkun á nýjustu gögnum sem borist hafa frá því á hádegi í dag. Unnin voru líkön út frá gervitunglamyndum og GPS mælingum. Líkön sýna að umfang kvikugangsins er verulegt og kvika er að nálgast yfirborð. Gangurinn nær frá Kálffellsheiði í norðri og liggur rétt vestan Grindavíkur og í sjó fram í suðvestur stefnu. Kvikugangurinn er um 15 km langur og kvikan liggur á um 800 m dýpi þar sem hún er grynnst. Út frá þessu má álykta að verulegar líkur eru á að kvika nái að brjóta sér leið til yfirborðs. Auknar líkur eru einnig á að kvika geti komið upp á hafsbotni.

Byggt á túlkun nýjustu gagna hefur Veðurstofan sent tilmæli til almannavarna að líkur á eldgosi hafi aukist frá því í morgun og að eldgos geti hafist hvenær sem er á næstu dögum.
