Update on the activity in the Reykjanes peninsula - 23.7.2020

Since the intense seismic swarm started in Fagradalsfjall on the 18th of July, the activity has been slowly decreasing over time. The acquisition of recent satellite images enabled mapping of new surface deformation in the area associated with the sequence of large earthquakes which occurred between the 18th and 20th of July. The satellite data processing clearly shows a deformation signal corresponding to approximately 3 centimeters of movement along a NE-SW oriented fault in the region of Fagradalsfjall.

An earthquake swarm in Fagradalsfjall - 20.7.2020

On 19th July at approximately 01:30 a.m. a seismic swarm commenced in Fagradalsfjall. Over 1700 earthquakes have occurred in this region since. The largest event occurred at 23:36 yesterday evening with a magnitude (M) of 5. Two other events greater than M4 occurred early this morning at 05:46 (M4.6) and 06:23 (M4.3), respectively. In addition, 22 earthquakes greater than M3 have occurred since midnight. Felt earthquakes have been reported by local residents as far Akranes in the west and Vík in the east. The seismic swarm is still ongoing with similar intensity.

A strong earthquake swarm offshore North Iceland - 22.6.2020

A strong earthquake swarm started on 19th of June offshore North Iceland, NE of Siglufjörður. Three earthquakes above M5.0 have occurred since the swarm started. On 20th of June a M5.4 earthquake occurred at 15:05 and a M5.6 at 19:26. Both these earthquakes were located around 20 km NE of Siglufjörður. The largest earthquake of the swarm occurred on 21st of June at 19:07 and was M5.8.

Evidences that Grímsvötn volcano is getting ready for the next eruption - 16.6.2020

During its active period, as it is since the eruption in 1996, Grímsvötn erupts on average each 5-10 years. The last eruption occurred in 2011 and it was a fairly large and powerful event. Between eruptions, the deformation data indicate the gradual accumulation of new magma at depth and the increased pressure in the system. In the last weeks scientists from the IMO measured SO2 in the southwest corner of the caldera in Grímsvötn, close to where the last eruptions in 2004 and 2011 took place.

Seismic activity around Mt. Þorbjörn has decreasing significantly - 4.5.2020

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. This data was presented during a Scientific Advisory Board, which met on 30th of April to discuss and review the current activity in Reykjanes Peninsula.

More research is needed to decipher the on-going activity at the Reykjanes Peninsula as a whole - 2.4.2020

On Thursday the 26th of March an on-line Scientific Advisory Board meeting was held to discuss the ongoing unrest in the Reykjanes peninsula. Scientists from IMO, University of Iceland, ISOR and representatives from Civil Protection, HS-Orka, ISAVIA-ANS, and the Environment Agency of Iceland attended the meeting.

HARMONIE - numerical weather prediction model 

HARMONIE is a numerical weather prediction model (NWP) that is non-hydrostatic and convection-permitting. It is operated at 2.5 km horizontal resolution over a domain that covers Iceland and the surrounding seas. At this resolution it is possible to simulate explicitly some processes that are important for clouds and precipitation as well as meteorological phenomena related to up- and downdrafts. In order to simulate the interaction between the atmosphere and the surface, the model takes into account different types of land surface as well as processes in and at the surface.
