Volcanic eruption officially over
The eruption began on the evening of Friday 19th March 2021 and lasted for six months, with several inactive periods. The eruption was major news, as volcanic activity on the peninsula is rare, and because it was close to inhabited areas. Various efforts were made to steer the lava, with varying results, but still it threatened infrastructure, including Suðurstrandarvegur road and a fibre optic cable. There was, however, no major damage.
“We will continue to monitor activity on the Reykjanes peninsula carefully, but we can say that this specific event, that began with a volcanic eruption at Fagradalsfjall on 19th March, is over—regardless of how things in the area develop. The only thing that is known for sure is that nature prevails,” wrote Sara Bersotti, the head of volcanic hazards at the met office.
Expansion is still being measured in the area and calculations and modelling are being worked on so that the measurements can be interpreted, but the results are not yet clear.
Volcanic activity on Reykjanes usually comes in periods, which means further eruptions on the peninsula are considered likely in the coming years.
The lava filed at Fagradalsfjall is still dangerous, even though the eruption is over. It is still hot in places, and the new lava is still settling, with regular cracking and collapses. Caution is advised in the area.
