Scientist from the Icelandic Met Office and the University of Iceland flew over the Bardarbunga area this morning to study in greater detail the cauldrons (depressions) that were discovered in a reconnaissance flight yesterday. No changes were visible.

An earthquake measuring 5 in strenght was registered in the northern part of the Bardarbunga caldera around 8:00 Thursday morning. The earthquake was measured at a depth of 3 kilometers.

The scientist went on a reconnaissance flight on Iceland Coast Guard plane TF-SIF yesterday and found 4 cauldrons or depressions in the south eastern part of Bardarbunga. The ice in that area is around 400-600 meters thick. There were no signs of an eruption. The cauldrons were 10-15 meters deep and 1km wide and formed a 4-6 km long line. They were said to possibly have been the result of melting, possibly an eruption, uncertain when. Heightened tremors have not been observed.

Sigurlaug Hjaltadottir, geophysicist at the Icelandic Met Office, said this morning that the cauldrons that were found yesterday were a clear sign of melting that could have taken place due to an eruption or because of massive geothermal activity. There were signs that the water level in Grimsvotn lake had increased in the last days, but it was unclear if that was due to the cauldrons and the water melting when they were formed.
