Glacial river

The Múlakvísl is a river in the south of Iceland in the west of the Mýrdalssandur plain .

Glacial river

It is a glacier river that gets its water from Mýrdalsjökull , especially through its glacier tongue Kötlujökull . Its floods are mostly gray-brown in color, as it entrains a lot of sediments .

At Selfjall , approx. 10 km east of Vík í Mýrdal , the ring road leads over a bridge over the Múlakvísl.

Glacier runs

Since increasing amounts of water from this river are an important indicator of impending volcanic eruptions of the Katla, it is monitored very closely.

1955

The predecessor of the bridge was torn away in 1955 during a glacier run with 2500 m³ / s water. A basin in the glacier had formed above the Kötlugjá , the fissure in the caldera of the Katla volcano that was created in 1918 . This indicated volcanic activity under the glacier, which in turn initiated the glacier run. However, there was no real outbreak in 1955.

July 2011

On July 9, 2011 there was another glacier run that had already announced itself hours and days earlier in series of tremors up to ten kilometers deep in the Katla region. A small volcanic eruption occurred under the glacier similar to 1955.

The course of the glacier again destroyed the 20-year-old bridge on the ring road on Múlakvísl. Due to a glacier warning from a water level early warning system, the road was closed to traffic about an hour before the bridge was destroyed, so that no one was harmed.

On July 11, 2011, the tremor under the Kalta had calmed down again.

On July 15, 2011, 1,500 people were transported across the Múlakvísl with the help of special vehicles; on July 16, a temporary bridge over the river, which has now been completed, was put into operation.
