An article recently published in the journal Frontiers in Earth Science on glacier changes in Iceland describes changes in the volume and mass of the Icelandic glaciers since they reached historical maximum extent at the end of the so-called Little Ice Age shortly before 1900. The results of a number of studies covering about 99% of the  glacier area are summarized in the article, which is a collaborative effort of many glaciologists at several institutes that conduct measurements and research on glaciers in Iceland.

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.

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.
