Geldingadala eruption number two

On March 19, 2021, after a long series of earthquakes in Reykjanes, a volcanic eruption began at 20:45 just east of Fagradalsfjall in Geldingardal. The eruption started slowly and lasted until September with a few breaks.  You can read more about that eruption here.

The eruption number 2 at Fagradalsfjall in Merardalir started on August 3, 2022. The chapter number two began in the expected long series of volcanic eruptions in Reykjanes for the next few years. The site of the eruption is close to last year’s eruption that lasted for about six months. According to the Icelandic Met Office, the exact location of the fissure is in Meradalir about 1.5 km north of Mt. Stori-Hrutur. The area is in southwest Iceland, about 15 km from Keflavik International Airport and about 25 km from the Reykjavík metropolitan area.

Just after 1 pm a 300-meter fissure opened right next to the former location of the volcano 2021 near Merardalur.  At first glance, the eruption seems to start with more force than the previous eruption, the lava spews reach about 50 meters into the air and the lava seems to flow over the older lava.
The eruption is considered to be relatively small and due to its location, there is low threat to populated areas or critical infrastructure. However, it is possible that pollution can be detected due to the gas release so people are advised against visiting the site.

On first two days, there have been no disruptions to flights to and from Iceland and international flight corridors remain open.
The eruption is classified as a fissure eruption (often referred to as Icelandic-type) and does not usually result in large explosions or significant production of ash dispersed into the stratosphere.

Here we will try to follow the progress of this eruption.
