Seismologist Björn Lund warns that the recent decrease in seismic activity around the Reykjanes Peninsula, following Friday and Saturday’s volcanic eruptions, could be a deceptive lull before another potential outbreak.
Lund, from Uppsala University, explains that in the three most recent eruptions in 2021, 2022, and this summer, earthquake activity decreased before the eruptions began. This pattern is a cause for concern for the current situation at Reykjanes, especially considering the increased magma penetration over a longer distance.
The seismologist also raised alarm regarding the location of the eruption, which is close to the town of Grindavik as well as heat and power plants. This proximity could lead to dangerous sulfur dioxide gas being released into the surrounding areas, making it crucial for authorities to closely monitor the weather and wind directions.
Despite the decreased activity observed over the past 24 hours, Lund stresses that the calm may not be an indication that the danger has passed. He highlights the importance of analyzing deformation measurements to gauge the earth’s surface and track any potential rise, as well as preparing for any future rapid changes in volcanic activity.
As the situation continues to unfold, experts are closely monitoring the region to provide timely warnings and guidance to the local population, emphasizing the need for vigilance and caution in the face of potential volcanic threats.
