Prior to the eruption, precautionary evacuations were executed in the nearby fishing village of Grindavik and at the popular Blue Lagoon geothermal spa, though it was unclear whether the spa was closed following the eruption. The Icelandic Meteorological Office confirmed that the eruptive fissure extended around half a mile, largely producing lava flows away from significant structures.

While there were no reports of damage or injuries, the authorities noted that southeast winds could potentially transport volcanic gas towards the vicinity of Iceland's main international airport, located about 20 miles northwest of Grindavik. However, travel operations at the airport remained unaffected as of early morning following the eruption. Iceland has historically experienced volcanic activity at intervals of three to four years, yet the recent surge—including 12 eruptions within the last four years from the Svartsengi volcanic system—highlights the notable geological dynamism of the region.
