A volcano has erupted in southwestern Iceland for the second time in less than a month, sending semi-molten rock spewing toward a nearby settlement.

The eruption just before 8 a.m. Sunday came after a swarm of earthquakes near the town of Grindavik, the Icelandic Meteorological Office said. The community was evacuated overnight, Iceland’s RUV television reported.

“Lava is flowing a few hundred meters north of the town, this is 400 to 500 meters,” Kristín Jónsdóttir from the Icelandic Meteorological Office told Iceland’s RUV television. “Lava flows towards Grindavik.”
