Scientists currently on a surveillance flight on the Icelandic Coast Guard airplane TF-SIF over Vatnajökull glacier state that they cannot detect any changes to the row of four cauldrons by Bárðarbunga first observed on their surveillance flight yesterday.
The scientists have been in contact with the Crisis Coordination Centre in Skógarhlíð, Reykjavík, run by the Department of Civil Protection, which notified national broadcaster RÚV of the information at 11:30 this morning.
The row of cauldrons extends to the southeast from Bárðarbunga on the watershed line between glacial river Jökulsá á Fjöllum and glacial lakes Grímsvötn. The cauldrons indicate glacial melt but it is uncertain in which direction the water will flood.
The water flow in Jökulsá á Fjöllum has not changed and the water level is normal for this time of year. The water level in Grímsvötn has heightened in the past days but it is unclear whether this is related to the cauldrons, as reported last night.
The cauldrons are believed to be the cause of sub-glacial geothermal activity or volcanic eruption. However, earthquake monitors don’t indicate a large eruption.
The seismic activity in Vatnajökull and north of the glacier has remained stable this morning after a magnitude 5.0 earthquake hit in the Bárðarbunga caldera shortly after 8 am.
TF-SIF is expected to land in Reykjavík in the early afternoon.
