    In response to a significant escalation in seismo-volcanic activity on the Reykjanes Peninsula in Iceland, characterized by an exceptional accumulation of magma, the intrusion of a substantial dike, and an intense earthquake swarm, the Icelandic Meteorological Office (IMO) and Civil Defense authorities have implemented critical safety protocols on November 10, 2023. These measures include the mandatory evacuation of Grindavík and the proclamation of a state of emergency

  • 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.
