Katla Rattles Again, New Flood in Múlakvísl?

A driver who passed across the river Múlakvísl in south Iceland late last night said it is likely that the river flooded. Sulfur could be smelt long before he reached the river, he said.

Múlakvísl is a glacial river which originates in Mýrdalsjökull, underneath which the volcano Katla lies. A minor eruption is believed to have caused a glacial outburst in Múlakvísl in July, which destroyed the bridge and tore a hole in the Ring Road.

Since then, minor earthquakes in the volcano have regularly been reported; on Sunday morning sensors picked up two small tremors in the Katla caldera measuring less than two points on the Richter scale, ruv.is reports.

Volcanologist Evgenia Ilyinskaya said the earthquakes were so small that there is no reason to be concerned.

In response to news of a possible new flood in Múlakvísl, the Icelandic Meteorological Office told ruv.is that sensors don’t show anything unusual but the water level in the river has been high lately due to heavy rain.

The sulfur smell, which has repeatedly been reported in the past months, is said to be caused by geothermal heat underneath the glacier.
