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.
Should a sub-glacial eruption start, Jökulsá á Fjöllum is expected to flood with potentially dangerous consequences. Bridges across the river might be destroyed and, as part of precautionary measures, people leaving near the river’s banks in Northeast Iceland have been informed of evacuation procedures in case of a flood.
Following observations by RÚV’s journalists of new eruptive fissures this morning, a surveillance flight by scientists was launched over the eruption site to review the situation. The area was subsequently closed off for everyone.
The scientists’ conclusions are as follows:
– Two new eruptive fissures formed south of the previous eruption site in Holuhraun, in a graben, that had formed above the intrusion, about 2 km away from Dyngjujökull.
– The eruptive fire fountains from the new fissures are substantially smaller than in the older fissure. Steam and gas rises in a southeastern direction from the fissure.
– The cauldron in Dyngjujökull seems to have grown deeper since the last observation.
– No changes are visible in Bárðarbunga.
