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.
No significant changes have been observed regarding the seismic activity in and around Bárðarbunga volcano under Vatnajökull glacier and in the dike intrusion connecting it with the eruption in Holuhraun since the Icelandic Met Office’s last report, yesterday morning.
The volcanic eruption at Holuhraun in the northeastern highlands continues with similar intensity. Lava continues to flow out of the lava lake which has formed in the crater, as observed by the crew of an Icelandic Coast Guard helicopter yesterday.
About 60 earthquakes have been detected in and around Bárðarbunga volcano during the last 24 hours, none of which were above 5.0 in magnitude, as stated in the Icelandic Met Office’s update this morning. Not much could be seen of the eruption on webcams due to poor visibility.
The volcanic eruption in Holuhraun continues with similar intensity. Around 200 earthquakes were detected in the caldera between Monday and yesterday morning, according to the latest Status Report from the Civil Protection Department’s Scientific Advisory Board, published yesterday.
