This is why Twitter and TikTok are pretty shitty socials ... Full of just old videos, false informations and even such things get more views than other serious things ...

Even if such things get shared by unknown people with few followers ....

But this is not a issue with the social, instead how people 💩 act ...

Meanwhile there is just ONE social that provides you facts. This is Telegram. Or you can use 1000 single socials, if you want to waste time checking 1000 single accounts ... @GrindavikTelegram

The October 1996 eruption within the Vatnajökull Glacier lasted for 13 days, with 3 km3 of ice being melted at the eruption site. The 0.4 km3 of erupted basaltic – andesite magma fragmented into glass, forming a hyaloclastite ridge 6 – 7 km long and 200 – 300 m high under 500 – 750 m of ice. The minimum concentration of exsolved CO2 in the 1x10^12 kg of erupted magma was 516 mg/kg, for S it was 98 mg/kg, for Cl it was 14 mg/kg, and for F it was 2 mg/kg. The pH of the melt water at the eruption site ranged from about 3 to 8. The volatile and dissolved element release to the meltwater in less than 35 days amounted to more than 1 million tonnes. The meltwater flowed from the eruption site into the Grímsvötn subglacial lake under a 270-m-thick ice cover.

The total dissolved flux was 1 million tonnes and the minimum C flux was equal to 0.6 million tonnes of CO2. The annual magmatic flux of CO2 to the atmosphere and surface waters in Iceland, mostly long-term degassing through volcanoes and geothermal systems, has been estimated to be of the order of 1 – 2 million tonnes (Arno ́ rsson and G ́ıslason, 1994). Volcanic eruptions are frequent in Iceland, about one every fifth year (Thorarinsson, 1981). Thus, a small eruption like in 1996 contributes 5 – 10% to the total annual CO2 magmatic flux from Iceland.

The Fagradalsfjall volcanic system is one of six volcanic systems on the Reykjanes Volcanic Zone. In the literature Fagradalsfjall volcanic system has either been classified as an individual system or a secondary volcanic swarm on the neighbouring Krýsuvík volcanic system. An eruption started on the system on March 19th in 2021, following more than a year of earthquake activity and inflation/deflation periods. This eruption put an end to ca. 800 years of volcanic quiescence on the Reykjanes peninsula and defines the beginning of a new eruptive period on the Reykjanes Volcanic Zone. It was also the first eruption on the Fagradalsfjall system in about 6000 years. About 10 postglacial eruptions are known from the system, all older than 6000 years.

The volcanic system is located between the Svartsengi and Krýsuvík volcanic systems and differs from the other systems in the Reykjanes Volcanic Zone as it includes neither a subaerial geothermal field nor a NE-SW trending fissure swarm. However, there are N-S trending tectonic faults. The characteristic volcanism formations are lava shields, of which one of the largest ones is Þráinsskjöldur. The highest point of the volcanic system is within the Fagradalsfjall tuya (ca. 390 m a.s.l.), after which the system is named.

The characteristic activity is effusive basaltic but size estimation of individual lava flows is hard as they are partly covered by younger formations. The system has erupted twice after volcanic activity resumed (in 2021 CE and 2022 CE). The first eruption lasted for six months and filled in a pre-existing valley landscape, covering 4,85 km2 with 0,15 km3 of lava. The second one lasted for about three weeks and added 0,01 km3 on top of the older lava covering an area of 1,3 km2.

The largest known eruption in Fagradalsfjall volcanic system is the formation of a shield volcano of a few km3 in volume. One such eruption has occurred in the last 14,000 years. Such an eruption is considered unlikely at present time.
