The Blue Lagoon geothermal spa — one of Iceland’s biggest tourist attractions — closed temporarily as a swarm of earthquakes put the island nation’s most populated region on alert for a possible volcanic eruption.
Guests rushed to leave the spa’s hotels in the early hours of Thursday, after they were rattled awake shortly before 1 a.m. by a magnitude 4.8 quake, the strongest to hit the region since the recent wave of seismic activity began on Oct. 25.
