After an apparent hiatus of eight and a half days, the main crater of Fagradalsfjall volcano in southwestern Iceland began to spew fire and lava again on Saturday
Scientists visited the site that day and made some interesting discoveries, according to the Facebook page of the volcanology and natural disaster group of the University of Iceland. The team notes that there are all indications that the eruption did not stop during this pause in surface activity. Obviously, the opening of the main vent is clogged, preventing magma from entering it.
"It also stopped the formation of very large gas bubbles, which explains the decrease in the intensity of the tremor," explains the Facebook post. “Nevertheless, periodic but weak tremors, constant gas release from the vent, red-hot lava in the skylights above the lava tubes and newly burnt vegetation along the edges of the lava in [valleys] Geldingadalir indicate that magma rose through the channel to the surface during 8, 5-day pause in surface activity."
From Saturday evening to Sunday morning, the eruption was very active and visible from afar, for example, from the town of Seltjarnarnes. Visibility was limited yesterday due to bad weather conditions - heavy rain and strong winds.
