Virkniyfirlit:
UPDATED VONA - Please disregard the previous one A Scientific Advisory Board met on 30th of April to discuss and review the current activity in Reykjanes Peninsula. The meeting was attended by scientists from the Icelandic Meteorological Office, University of Iceland - Earth Sciences and ÍSOR, and also representatives from the Civil Protection, ISAVIA-ANS and Police Dept of the South-Iceland. In the beginning of April the uplift in Þorbjörn decreased and, in the second part of the month, it stopped. The area around Þorbjörn is now most likely recovering after the large induced stress, and the injected magma is cooling down and contracting. Along with reduced deformation, seismic activity has decreasing significantly. These data indicate that the injection of magma beneath Þorbjörn has stopped and this second phase of uplift due to magma intrusion can be considered closed. Even though there are no observations of ongoing uplift around Þorbjörn, there are indications of minor deformation over a larger area. The current observations and the course of events over the last several months suggest that there is an active long-term process ongoing in the area. The possibility of renewed activity in the near future at Þorbjörn, Reykjanes or elsewhere on the Reykjanes Peninsula cannot be discarded. In light of the current reduced activity in the area the color code for aviation is moved back from YELLOW to GREEN. The Uncertainty level issued by the Civil Protection on the 26th of January for the Þorbjörn area is still in force.
