Tremors Cause Flood in Glacial River Skeidará

By Iceland Review

The Icelandic Meteorologist Office detected subterranean disturbances near Grímsvötn lakes on Vatnajökull glacier, south Iceland, on Wednesday night causing increased flow of water and electrolytes in Skeidará river, leading from the glacier.

“Then there is no doubt about it; Skeidará has started flooding,” Gunnar Sigurdsson, hydrologist and engineer at the National Energy Authority told Morgunbladid. “We expect this to be a large flood.”

Once the water level in Grímsvötn lakes has reached a certain height it tunnels its way down through Skeidarárjökull glacier, one of the southern arms of Vatnajökull, and into Skeidará.

This phenomenon is known as Skeidarárhlaup in Icelandic and happens regularly. The last flood in Skeidará took place three years ago and was followed by a volcanic eruption underneath Vatnajökull.

The volume of water in Skeidará yesterday was comparable to a good summer’s day and the smell of sulfur was in the air on Skeidamerkursandur plains, through which the river flows to the ocean.
