F88 and F910 West of Askja are now 'no passage' in case of potential flood by glacial meltwater.
F910 West of Askja are now 'no passage'
West end of F910 hasn't opened at all yet this summer, which is nothing to do with volcanoes. It was still showing as closed on vegagerdin.is last night but is now showing as not known. F88 has been closed recently, and predating the volcano scare, so I'm sure it's nothing to do with the volcano and in any case it seems too far away, more likely some ford was impassable. It was also showing as closed last night but has now shown as not known.
They were both showing as '?' earlier, but it's back to 'no passage' now.
"The Police Commissioner of Húsavík has decided to close Gæsavatnaleið road and other highland roads east of Skjálfandafljót up to Askja. The road to Herðubreiðarlindir (F88) has also been closed due to potential flooding in the area following an eruption." via Grapevine
F910 reopened after the Askja area landslide was deemed safe. F88 was 'impassable' north of Herdubreid due to river levels, but is now 'no passage' for the full length.
1430 quakes and counting, highest up to 3.8 on the scale!
