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.

The Civil Protection Scientific Advisory Board meets to discuss the status of Grímsvötn - 19.6.2020

The meeting reviewed activity in Grímsvötn in the past months and discussed measurements made in and around Grímsvötn in early June. While seismic activity has been increasing over the past year, in June it was still lower than in the months leading up to the most recent eruptions in 2004 and 2011. Measurements of land deformation show that land continues to rise since the previous eruption with no significant changes in the last year. The biggest measurable change was that sulfur dioxide (SO2) was detected close to the last eruption site. SO2 emissions give a strong indication of magma degassing.

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.

Past temperature conditions in Iceland

This has been a period of a general rise in temperatures, interrupted by two cold periods. The late 19th century cold period was colder than a corresponding period in mid to late 20th century.
