Geological assessments suggest increased volcanic activity near Grindavík on Reykjanes Peninsula in Iceland

Recent geological assessments indicate an increased likelihood of volcanic activity on the Reykjanes Peninsula within the next two to three weeks. The Icelandic Meteorological Office has raised its hazard assessment following the latest data, highlighting a significant risk of an eruption occurring near Grindavík.

Ongoing ground deformation has been observed continuously over recent weeks, further contributing to these concerns. Current modeling suggests that the total amount of magma which has accumulated since the last eruption is approaching 16 million cubic meters. It is estimated that between 13 and 19 million cubic meters need to accumulate in the magma chamber before a volcanic eruption can take place.

Two primary scenarios are considered most likely for an eruption. The first suggests that volcanic activity could initiate between Stóra-Skógfell and Sundhnúkur. In this case, lava flows might reach Grindavíkurveg near Þorbjörn in less than 90 minutes and extend to the region near Svartsengi within three hours.

The alternative scenario proposes that the eruption could occur south of Sundhnúk, near Hagafell or further south. This could allow lava flows to reach Nesvegi and Suðurstrandavegi in under 90 minutes, possibly cutting off land evacuation routes within approximately six hours.

Authorities remain vigilant as the situation develops.
