the Day/Night-quiet/busy anomaly started on the 23rd Aug, before the eruption!!
New eruptive fissure in the Holuhraun eruption is much closer to the Dyngjujokull glacier than the previous ones, and creeping towards the glacier, says volcanologist Armann Hoskuldsson, who surveyed the new fissure this morning. Volcanic tremor indicates the fissure opened around 4 AM.
"This cauldron in the glacier was spotted a few days ago, but seems to have gotten slightly larger," said Dr. Sigmundsson, a Geophysicist at the University of Iceland's Institute of Earth Sciences. "Due to the events in the blowout lava, and the presence of the magma intrusion beneath the glacier, we can not exclude that 'a small subglacial eruption has occurred under this depression in the ice," said Dr. Sigmundsson.
Much brennisteinstvíildi measure around the eruption site, as yesterday. Conduction Jökulsá the mountains has increased slightly. There is considerable activity in older vent and step gufustrókar her up to 15 thousand feet. This is shown in the status report researchers council, which was published on the IMO website at lunchtime. It turns out that sigketillinn in Dyngjujökli seems to have deepened.
Measurements in glacial river Jökulsá á Fjöllum show a slight increase in conductivity, according to an update on the Holuhraun eruption from the Scientific Advisory Board posted on the website of the Icelandic Met Office earlier this afternoon.
