Scientists say there is a slight and ongoing decrease in volcanic and seismic activity at the site of the Holuhraun volcanic eruption in Iceland, which has been going on for over three months.
The Scientific Advisory Board has reviewed data about the development of events in Bárðarbunga volcano and the volcanic eruption in Holuhraun from the beginning of the unrest until present day. The new lava field is the largest in Iceland since the Laki eruption (1783-1784) and probably the third...
There have been insubstantial changes to the volcanic eruption in Holuhraun over the last two weeks. Seismic activity in Bárðarbunga volcano under Vatnajökull glacier continues to be strong. The biggest earthquake since noon on Friday was of magnitude 4.5.
A considerably large earthquake of magnitude 5.1 occurred at Bárðarbunga volcano under Vatnajökull glacier at 6:14 this morning. Its epicenter was 5.7 km northeast of the volcano and at a depth of 6.9 km.
A total of 63 earthquakes above magnitude 5.0 have occurred in and around Bárðarbunga volcano under Vatnajökull glacier between August 16 and November 25. Lately, the frequency of such big earthquakes has declined; last week there were five days between them.
The first data received from new seismographs put up on Bárðarbunga volcano, which lies under Vatnajökull glacier, last week, shows that the magma is much closer to the surface than previously thought.
The volcanic eruption in Holuhraun continues to be strong, although its productivity has decreased from mid-September. The activity is similar to what it has been in the last two weeks but the lava flow is more fluctuating.
The volcanic eruption in Holuhraun continues with similar intensity as it has for the last two weeks. Lava continues to flow out of the lava lake in the crater to the east-southeast. The lava field now measures approximately 72 square km and is twice the size of Lake Mývatn.
An earthquake of 5.4 in magnitude hit the northern caldera rim of Bárðarbunga volcano under Vatnajökull glacier at 1:37 am yesterday. Following the event, seismic activity in the intrusive dike, connecting the volcano with the eruption in Holuhraun, increased slightly.
