Volcanic pollution rising as eruption continues at Reykjanes Peninsula, Iceland

The levels of sulfur dioxide (SO2) are rising in the vicinity of Grindavik due to the ongoing volcanic eruption on the Reykjanes Peninsula, Iceland. The gas pollution has reached unhealthy levels, as reported by the Icelandic Meteorological Office (IMO).

Volcanic activity near Grindavik has not decreased as quickly as it did in previous eruptions, IMO reported at 15:45 UTC on November 25, 2024.

“Since yesterday in the early evening [LT], volcanic tremor and visible activity from the eruption have further diminished, but the activity stabilized again after midnight. Nevertheless, the eruption remains quite powerful, and the activity has not decreased as quickly as it had in previous eruptions in the Sundhnúkur crater row. For comparison, the current lava flow is estimated to be on par with the most vigorous eruptions at Fagradalsfjall,” IMO volcanologists said.

Volcanic activity remains strong with the lava volume estimated at 43 million m3 (0.010 mi3), as of Saturday, November 23 — three days into the eruption. It covered an area of about 8.5 km2 (3.28 mi2), which is around 65% of the amount produced in the last eruption which lasted 14 days.

Land continues to subside in Svartsengi, though at a slower rate compared to what was observed at the start of the eruption.

“It is still too early to determine whether magma accumulation will persist under Svartsengi. The flow of lava from eruptive vents needs to decrease further before any conclusions can be made about continued magma accumulation,” IMO said.

Today, wind directions are shifting and becoming variable, meaning volcanic pollution could spread to the surrounding areas in the southwestern part of the country.

Authorities deployed 12 water cannons, to stop the advancing lava flows, on the L3 defense wall on November 24. These were being used to cool a 360 m (1 181 feet) section of lava that threatens the Svartsengu geothermal facility and the Njarðvikuraeð hot water pipeline which are crucial for the Suðurnes region.

The initial testing of the cooling process was successful and operations have begun with 6 eastern cannons. The remaining units are scheduled to follow with the process expected to take several days.
