• IMO confirms continued inflation, seismic unrest at Mt. Þorbjörn, Iceland

    ByTW

    The Icelandic Met Office (IMO) has issued an update on the seismic and volcanic activity at Mt. Þorbjörn on the Reykjanes Peninsula, providing new data on the ongoing seismic unrest that began in late October. The uplift at the GNSS station has seen additional enlargements since the 7 cm rise previously reported over a 10-day period, reflecting continued subterranean pressure changes. The IMO, alongside the Civil Protection Agency, remains on high alert for signs of magma ascent, which could indicate a new phase in the volcanic activity of the area.

    ByTW

    An exceptionally intense earthquake swarm lasting nearly two hours started at Þorbjörn in Iceland at 08:40 on October 31, 2023. The largest event registered an M3.7, and the activity signaled potential magma movement at depths between 1.5 km and 5 km (0.93 – 3.1 miles).

    A powerful earthquake swarm started at Krísuvík volcano, just northeast of Fagradalsfjall and a short distance north of Fagradalshraun lava field, on July 30, 2022, at a depth of about 5 to 7 km (3 – 4 miles). As a result, the Icelandic Meteorological Office (IMO) raised the Aviation Color Code for the volcano to Yellow. The last eruption at this volcano took place in 2021.
