Die elektrische Leitfähigkeit nimmt in Skálm und Múlakvísl zu, aber der Wasserstand ist an beiden Orten recht stabil.
„Das ist kein so großes Ereignis wie vor zwei Wochen“, sagt Elísabet Hauksdóttir, Expertin für Naturkatastrophen beim isländischen Wetteramt in einem Interview.

A little run in Múlakvísl 19.8.2026 Over the past 24 hours, the electrical conductivity in Múlakvísl has risen steadily and has become unusually high for the time of year, measuring around 285 microS/cm. Conductivity measurements indicate the amount of geothermal water in rivers, and high values ​​indicate that a small glacial outburst flood is underway. At present, the water level in the river has not risen in line with the increase in conductivity, but it is possible that this could happen in the coming days. Flashes of this magnitude are well known in Múlakvísl. The flash is accompanied by significant gas pollution this time, but the Icelandic Meteorological Office has a gas meter at Láguhvoli, which is about 2 km from the edge of the Kötlujökull glacier. Last night, hydrogen sulfide (H2S) was measured there above health protection limits. It is therefore advisable to stay near the river or be near its sources at the edge of the glacier. The calm winds in recent days also increase the risk of gas accumulating in depressions. If people experience symptoms, such as a burning sensation in the nose or eyes, they should leave the area immediately. The Icelandic Meteorological Office's 24-hour watch continues to monitor measurements in the area and sends out new information if there are any changes.

Increased discharge and significant gas pollution in Múlakvísl 21.8.2026 Updated 20 August The glacial outburst flood in Múlakvísl, which began on 18 August, now appears to be subsiding. Both conductivity and discharge have decreased since yesterday, and currently there is no gas pollution being detected in the area. However, it is still too early to say whether the event has ended. Travelers are still urged to exercise caution and to leave the area if they notice symptoms that could indicate gas pollution. The Icelandic Meteorological Office will continue to monitor the area closely and provide updates as needed. Pic 1 The graph shows conductivity measurements in Múlakvísl at Route 1 (Þjóðvegur 1) from 17 August until this morning, 21 August. The water level in the river did not rise significantly, but the river spread out across its channel, indicating that discharge had increased. The Icelandic Meteorological Office's webcameras near Múlakvísl show this in the following images. Video The image on the left shows Múlakvísl at Láguhvolar, and on the right at Route 1 (Þjóðvegur 1), from 18–21 August.

Increased discharge and significant gas pollution in Múlakvísl 20.8.2026 The glacial outburst flood that began in Múlakvísl on 18 August is ongoing. Since yesterday, electrical conductivity and discharge in the river have increased, and gas pollution continues to be detected in the area. Yesterday evening, electrical conductivity rose fairly sharply and now measures just over 500 µS/cm, which is unusually high compared with recent glacial outburst floods in the river. Conductivity last reached a similar level during the glacial outburst flood in July 2017, when it peaked at 580 µS/cm. So far, the water level in the river has not risen significantly. However, webcam footage shows that the river has spread across a wider area, indicating that discharge has increased. Several geothermal areas are known to exist beneath Mýrdalsjökull. Meltwater drains continuously from these areas, and the local topography determines whether or not it accumulates. The amount of water that collects in these subglacial lakes before an outburst occurs varies, as does the rate at which they drain. Glacial outburst floods of this magnitude are well known in Múlakvísl. This event is accompanied by significant gas pollution. People are therefore advised not to remain near the river or close to where it emerges at the glacier margin. The calm weather in recent days also increases the risk of gas accumulating in depressions. Anyone experiencing symptoms such as irritation of the nose or eyes should leave the area immediately. The Icelandic Meteorological Office is closely monitoring developments and remains in direct contact with Civil Protection.

The second race in Múlakvísl this month The river's water level has not risen, but it could. Tourists are asked to exercise caution as gas has been detected near the river. Increased electrical conductivity in Múlakvísl indicates that a small glacier outburst flood has begun. "It has been increasing slowly and steadily over the past three days and is now measuring around 250 µS/cm, which is our first warning level. It is usually around 100," says Sigríður Magnea Óskarsdóttir, a natural hazard specialist at the Icelandic Meteorological Office. "The water level hasn't increased in the river, but webcams show that it has only spread to a few more eels. They tend to burrow rather than let the water level rise." Warning about gas pollution The Icelandic Meteorological Office's announcement states that gas pollution is being measured near the river and tourists are therefore encouraged to exercise caution. "Those who experience symptoms that could indicate gas contamination, such as burning in the eyes or throat, are urged to leave the area," the announcement said. Geothermal boilers tend to run out in late summer. A small glacial outburst flood began in Múlakvísl on August 18th and lasted for several days. Considerable gas pollution and high electrical conductivity were measured. It reached over 500 µS/cm on August 19th. Sigríður says there is nothing unusual about two races taking place so close together, it is not unknown. "There are many geothermal boilers under Mýrdalsjökull. They tend to empty in late summer. Sometimes they manage to empty completely, sometimes not." The news was updated with an interview with a natural disaster expert.

Updated 1 September Electrical conductivity in Múlakvísl has remained high for this time of year over the past few days. Values have ranged between 250 and 270 μS/cm since 30 August. Electrical conductivity measurements indicate the amount of geothermal water present in rivers, and high values suggest an ongoing discharge of geothermal water, similar to that observed on 19 August. The river level has not risen alongside the increased conductivity, although a rise cannot be ruled out in the coming hours. Glacial outburst floods of this magnitude are well known in Múlakvísl. This geothermal discharge is currently accompanied by significant gas pollution. The Icelandic Meteorological Office operates a gas monitor at Láguhvolar, approximately 2 km from the margin of Kötlujökull glacier. An increase in hydrogen sulphide (H₂S) was detected overnight, and concentrations are now above health protection limits. People are therefore advised not to remain near the river or its source at the glacier margin. Winds in the area are light or calm, allowing gas to accumulate in depressions in the terrain. This may pose a serious hazard to travellers in the area. Anyone experiencing symptoms such as irritation of the nose or eyes should leave the area immediately. The Icelandic Meteorological Office's 24-hour monitoring team continues to monitor measurements in the area and will issue further information if conditions change
