Possible Katla Eruption in 2011

Geologist Páll Einarsson believes that the volcano Katla could have already erupted in 2011, causing the flood that swept Múlakvísl bridge away. Vísir reports.

The last time Katla was known to have erupted was in 1918, an eruption that lasted 24 days, extending the Icelandic south coast by up to 5 kilometers (3 mi).

According to Páll, research indicates that three minor eruptions have taken place in the volcano since its eruption in 1918, the last of which was in 2011. Although they weren‘t powerful enough to break through the thick glacial ice, they did cause several floods.

A flood had occurred on July 9th 2011, originating from Katla. It ruptured the ring road and washed away the Múlakvísl bridge. A flyby over Katla showed at least four large calderas had formed in the glacier.

Páll does, however, point out that nothing is completely confirmed as of yet. After all, it is hard to determine whether an eruption had taken place when nobody was there to see it in the first place. He nevertheless finds it more likely than not.

“According to measurements that were done later, mainly seismic surveys, most of them indicate that the flooding was caused by an eruption and further research has supported that theory.”
