Iceland’s Reykjanes Peninsula volcanic activity appears to be winding down

Recent seismic activity on the Reykjanes Peninsula appears to be winding down, with indications suggesting that the volcanic eruption in the Sundhnúkur crater row that began on August 22 may soon come to an end, or may have already concluded. Iceland’s Meteorological Office plans to evaluate the situation and possibly declare the end of the eruption tomorrow.

Currently, there seems to be very little, if any, volcanic activity. Minney Sigurðardóttir, a natural hazard specialist at the Meteorological Office, noted that drone flights conducted earlier showed no signs of activity. Additionally, volcanic tremors have significantly decreased, prompting officials to monitor the situation overnight before making any official statements.

There are also signs of land uplift occurring again under Svartsengi, marking the ninth occurrence since October of last year. Prior to the formation of a major magma intrusion on November 10, 2022, a substantial amount of magma had accumulated, followed by another magma intrusion that took place without an eruption. The current eruption at Sundhnúkur is the seventh in this sequence.

Researchers from the Meteorological Office mentioned that the current land uplift aligns with patterns observed after the eruption at the end of May, which also became noticeable approximately two weeks post-eruption.

As the situation continues to develop, authorities remain vigilant, ready to provide updates based on the latest monitoring results.
