New fissure openings have formed several times since the eruption at Fagradalsfjall, Iceland began on March 19, 2021. On May 2, the activity at the volcano changed, producing huge lava fountains — the biggest since the eruption started. The video was captured by Sigfús Steindórsson around 02:00 local time on May 2.
Lava fountains were seen reaching about 300 m (985 feet) above ground lasting from 3 to 10 minutes.
The Icelandic Met Office (IMO) confirmed considerable changes in volcanic activity, starting at around 01:00 LT on May 2.
“It’s not clear what causes these changes in volcanic activity, but it cannot be ruled out that there have been changes in magma flow, the chemical composition of magma/gas or that there have been changes in the feed system,” IMO said.
“In light of this changed activity, the size of the danger area at the eruption sites is being reassessed.”
