Reykjanes volcano news & activity updates
Mt. Thorbjorn volcano (Reykjanes peninsula, Iceland) activity update: seismic swarm recorded
Tuesday Feb 18, 2020 09:19 AM | BY: MARTIN
The Icelandic Met Office (IMO) recorded an earthquake swarm since 15 February at the southwestern tip of the Reykjanes peninsula. Over 120 earthquakes were detected by the seismic network with magnitude below M 3.0.
Earthquake activity around Thornbjorn volcano has decreased over the past days but is still above average, less than when it peaked in the end of January.
Additional monitors have been installed around Thorbjorn. Gas will be monitored regularly and scientists recommend the continuing monitoring of the area.
Icelandic scientists measured that in some places about 5 cm ground uplift have taken place since the start of the seismic crisis and that the intrusion is likely located at 3-5 km depth in an area just west Thornbjorn.

Reykjanes volcano (Reykjanes peninsula (SW Iceland)) activity update: Alert level raised to Yellow- earthquake swarm, inflation
Monday, Jan 27, 2020
IMO reports: An inflation has been detected since January 21st and is centred just west of Mt. Thorbjorn on Reykjanes peninsula. The inflation is unusually rapid, around 3-4 mm per day and has accumulated to 2 cm to date. It has been detected both on continuous GPS stations and in InSAR images. The inflation is most likely a sign of magma accumulation at a depth of just a few km. If magma accumulation is causing the inflation, the accumulation is very small, with the first volume estimate is around 1 million cubic meters. ... [more]

A shallow (10 km) magnitude 4.8 earthquake with many pre- and aftershocks (or a seismic swarm) occurred this morning (Sun) at 07:34 UTC at the SW tip of the Reykjanes peninsula, on the SW active rift zone. The swarm of earthquakes included several quakes of magnitude 3 and higher. The strongest earthquake was widely felt in SE Iceland. ... [more]

Yesterday, there was a lot of earthquake activity on Iceland. At noon, a swarm with about 50 quakes partly preceded and followed a magnitude 4.2 quake at 5.8 km depth beneath the Reykjanes peninsula, near the axis of the the SW volcanic rift zone. Most quakes were between magnitudes 1-2 and at around 5 km depth. ... [more]
