Increased Electrical Conductivity in Múlakvísl River; Gas Pollution Warning Issued

Recent measurements show a steady increase in electrical conductivity in the Múlakvísl river in Iceland, reaching approximately 240 µS/cm over the past few days. This rise in conductivity is a key indicator of the amount of geothermal water present in rivers and suggests that a small glacial flood is currently in progress.

While the water level in the river has not yet risen in correlation with the increased conductivity, the Icelandic Met Office has not ruled out the possibility of a rise in the coming days. The office continues to monitor the situation closely.

Adding to the environmental concerns, gas pollution has been detected in the vicinity of the river. Tourists and visitors in the area are strongly advised to be vigilant and exercise caution. Those who experience symptoms potentially related to gas pollution, such as stinging sensations in the eyes or throat, are urged to evacuate the area immediately.

This follows a previous glacial flood in Múlakvísl that began on August 18 and lasted for several days. During that event, significant gas pollution and high electrical conductivity, peaking above 500 µS/cm on August 19, were recorded. The Met Office will provide further updates as the situation develops.
