Skeiðarárjökull ice sheet from satellite (image: Kristín Jónsdóttir/twitter)
Kristín Jónsdóttir from the Icelandic Meteorological Office (IMO) notified on her Twitter account that the ice sheet has continued to drop and reached about 60 cm in total subsidence.
The glacial flood (jökulhlaup) from Grímsvötn volcano has likely started. New measurements reveal an estimated glacial flood peak in the next 5-10 days. The origin peak on 5 December didn’t happen.
Never a dull moment @Vedurstofan. The iceshelf above #Grímsvötn 1km3 subglacial lake has dropped by some 60cm indicating a #Jökulhlaup is underway! Likely it will reach the outlet of Skeiðarárjökull in the next ~48hrs and the flood will peak in 5-10 days!https://t.co/gJeEdym7qn pic.twitter.com/TruSMG4Zu7
