Significant ground deformation detected associated with recent earthquakes
Last week a series of earthquakes occurred on the Reykjanes Peninsula, between Fagradalsfjall and Kleifarvatn - the largest of which was a magnitude 5.6 earthquake in the vicinity of Núpshíðarháls, which occurred at 13:43 on 20th October. The maps displayed here show ground deformation associated with movement on faults during the period 16th-22nd October.

M5.6 at the Reykjanes peninsula
Seismic
activity has decreased significantly in recent days. About 180 earthquakes of
magnitude 2.2 or less were detected the last two days, for comparison, during
the first 24 hours following the 5.6 earthquake in Núpshlíðarháls, about 1700
earthquakes were detected in the area.
The Aviation Color Code for Grímsvötn changed from green to yellow
The Icelandic Met Office has changed the aviation color code for Grímsvötn volcano from green to yellow. Volcanic activity at Grímsvötn has been gradually increasing over time as indicated by several regularly monitored geophysical and geochemical parameters that are now above the known background level.

Update on the activity in the Reykjanes peninsula
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
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
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.
