Iceland Eruption Triggers Evacuations, Air Quality Warnings

A major volcanic eruption occurred on Iceland's Reykjanes Peninsula on July 16, 2025, following a seismic swarm and resulting in a fissure estimated to be between 700 meters and 1.5 miles long. Evacuations were carried out at the Blue Lagoon geothermal spa, the town of Grindavik, and surrounding areas as a precaution, although no immediate threat to infrastructure was reported. Lava, volcanic gases, and volcanic glass fibers known as 'witches' hairs' were released, raising air quality and health concerns. Despite these risks, flights at Keflavik airport and broader air traffic were not disrupted, and the event was described as highly localized. Authorities assured that Iceland remains safe and open for travel, with ongoing scientific monitoring of the situation. The eruption marks the 12th in the region since 2021 and underscores the persistent volcanic activity that shapes life and tourism in Iceland.
