The Icelandic volcanologists of the Institute IMO express concern about the current situation on the Reykjanes Peninsula. In the vicinity of Grindavik, there have been repeated swarm quakes in recent months, which were quite strong. Since 21 January, GPS measurements now show a rise in the ground that has not been seen there for decades. Under the volcano Þorbjörn the ground is rising by 3-4 mm per day. This rise is caused by magmatic fluids rising under the volcano. In all probability it is magma that causes Þorbjörn to rise. As a result, the civil defence has declared the VONA warning level “yellow”. Residents of the area will be invited to an information meeting tomorrow. There they will be informed about how to prepare for a possible volcanic eruption.
