Volcanic eruption begins at Sundhnúksgígaröð on Reykjanes peninsula in Iceland

A volcanic eruption commenced last evening at the Sundhnúksgígaröð, located on the Reykjanes peninsula in Iceland. Currently, there are no imminent threats to infrastructure, following a significant series of earthquakes just prior to the eruption.

The new fissure that opened overnight measures approximately one kilometer in length, with volcanic activity remaining strongest at its northern end. Decreased seismic activity has been noted since this new vent opened, and lava flow is currently around 100 cubic meters per second—about one-twentieth of the initial rate.

Witnesses report that many traveled to the area to observe the eruption, with some parking along the roadside, leading to concerns for public safety. Despite police warnings, many sought closer views, prompting local authorities to emphasize caution. The eruption is now producing a lava field that spans roughly 12 square kilometers and is moving slowly in the northeast direction.

Grindavík’s mayor expressed relief that the eruption occurred at a safe distance from town, indicating that there has been no immediate danger to local residents. During an emergency meeting, officials declared the area safe and lowered the public alert level from emergency to alert status.

As monitoring continues, authorities are assessing the situation and preparing for potential lava flows that could threaten critical water and geothermal infrastructure. New surveillance measures, including air traffic over the region, have been implemented to maintain awareness of any developments related to the eruption.
