The town of Grindavik has experienced repeated threats in recent years after the once-dormant volcano on the Reykjanes peninsula began erupting again after 800 years of no activity.

A volcanic eruption in southwestern Iceland has once again forced the evacuation of local residents and the internationally known Blue Lagoon geothermal spa, the national broadcaster RUV reported.

"Based on GPS measurements and deformation signals, it is likely that this was a relatively small eruption."
