The Scientific Advisory Board for Civil Protection met this afternoon. The meeting reviewed the processing of the latest measurements and data that scientists at the Meteorological Office, the University of Iceland and ÍSOR have been working on.
The results of the meeting are roughly as follows:
Less seismic activity:
Earthquake activity on the Reykjanes peninsula has been lower over the last 24 hours compared to the activity over the weekend. There have been a number of small earthquakes in the last 24 hours, which is a sign of how divided the seismic activity has been in this cycle, which began about three weeks ago.
Magma continues to flow into the corridor.
The latest satellite images and GPS measurements indicate that magma continues to flow into the magma chamber. Data indicate that the movement of the magma chamber to the south has stopped.
Seismic activity and probable eruption sites have shifted
The greatest seismic activity associated with the magma tunnel, has shifted about 4-5 km northeast of the area by Nátthaga and is now located northeast of Fagradalsfjall, in the middle of the magma tunnel.
Based on seismic activity over the last 24 hours, processing from GPS measurements and satellite images, the most probable eruption area has moved from Nátthaga northeast along the magma tunnel to the northeastern part of Fagradalsfjall.
Part of the magma solidified
The magma chamber has now been forming for about three weeks and it is likely that part of it has solidified. However, magma solidification in part of the corridor does not reduce the likelihood of an eruption in the area.
Scenarios remain valid
Scenarios that have been published are still valid, including the fact that an earthquake of magnitude up to 6.5 can occur in the area between Kleifarvatn and Bláfjall.
