In the past 24 hours the seismicity activity recorded in and around Bárðarbunga volcano in Vatnajökull glacier was slightly more intense than the 24 hours prior. More than 100 earthquakes were detected in the period, all below magnitude 5.0.
Seismicity continues in Bárðarbunga volcano in Vatnajökull glacier. A magnitude 4.4 earthquake hit shortly before 2:30 last night and the strongest earthquake recorded there yesterday was magnitude 5.1. Geothermal heat continues to increase in Bárðarbunga.
The volcanic eruption in Holuhraun continues with similar intensity to recent weeks. There were over 200 earthquakes in the Bárðarbunga caldera over the weekend, 44 of which were larger than magnitude 3.0. The largest were magnitude 5.3.
Seismic activity in the Bárðarbunga system and volcanic activity at the eruption site in Holuhraun is comparable to recent days, the Icelandic Met Office reported this morning. A magnitude 5.3 earthquake hit on the northern rim of the caldera at 08:36 am.
Three earthquakes of magnitude 4.5 or larger have hit the area around Bárðarbunga volcano in Vatnajökull glacier in the last 24 hours. In the past days, earthquakes around magnitude 5.0 have occurred in the area at an interval of approximately 30 hours.
The results of a new study on two large earthquakes in North Iceland in 2012 and 2013 indicate that changes in the chemical composition of groundwater in areas prone to earthquakes may be used to predict large earthquakes and to improve knowledge of processes in the earth’s crust.
The lava which has flowed from the craters in Holuhraun now covers 60 square km (23 square miles). The eruption is ongoing, although the volcanic activity has decreased somewhat. Scientists are examining data more closely and re-estimating the situation.
A subsidence of approximately 15 cm (5 in) occurred in the caldera of Bárðarbunga volcano in Vatnajökull glacier following a magnitude 5.4 earthquake hitting the northern caldera at 11:15 am yesterday, as indicated by the Icelandic Met Office’s GPS monitor in the caldera.
An increased number of earthquakes have been detected in and around Bárðarbunga volcano under Vatnajökull glacier in the past days. In the last 24 hours, almost 130 earthquakes have been detected at Bárðabunga.
