Glacial Flood in Múlakvísl Accompanied by Significant Gas Pollution

A small glacial outburst flood is occurring in Iceland's Múlakvísl river, evidenced by a steady increase in electrical conductivity over the past few days, according to the Icelandic Met Office. While the river's surface level has not yet risen significantly, this could change in the coming days.

These types of floods are common in Múlakvísl, which originates from the Mýrdalsjökull glacier. However, this particular event is notable for the accompanying gas pollution. A gas monitor located near the Kötlujökull glacier edge has detected hydrogen sulfide levels exceeding health limits overnight.

Authorities are warning the public to exercise caution when near the river or its sources at the glacier's edge due to the significant gas emissions. The calm weather conditions in recent days have exacerbated the risk, allowing gases to accumulate in low-lying areas. Individuals experiencing symptoms such as burning sensations in the eyes or nose are advised to leave the area immediately.

The Icelandic Met Office continues to monitor the situation closely and will provide updates if conditions change. The presence of gas pollution alongside the glacial flood highlights the complex environmental factors at play in the region.
