Two earthquakes were recorded in Mt. Grímsfjall by the Grímsvötn lakes on the Vatnajökull icecap, the largest glacier in Europe, this morning, measuring 4.2 and 3.5 on the Richter scale. These are probably the strongest earthquakes to hit in this area since 1934. Experts at the Icelandic Meteorological Office are currently reviewing data to see whether this is the case, visir.is reports. The earthquake that hit in 1934 measured 4.5 points on the Richter scale in strength and led to a volcanic eruption. Stronger earthquakes have hit Vatnajökull since but by Bárdarbunga in the glacier’s northwestern part. Grímsvötn are located in the western part of the glacier. Grímsvötn flooded late last year which was thought to be an indicator of an upcoming eruption. However, no eruption took place at that point.
