Considerable seismic activity has been detected on the Reykjanes peninsula last week and the activity has been greatest at Svartsengi and in the vicinity of Grindavík. A total of 1,700 earthquakes have been detected in the automatic system in this area this week, the largest being about 2.9 in magnitude. GPS stations in the vicinity of Þorbjörn have in the last two weeks shown changes that indicate slight expansion at Svartsengi. 'These displacements we see are still small, around 10-15mm where they are greatest', says Benedikt G. Ólafsson, expert in the field of crustal movements at the Icelandic Meteorological Office, but Benedikt in collaboration with the University's Institute of Earth Sciences closely monitors crustal movements in the area.
