Early on Sunday, a new volcanic eruption began outside the Icelandic town of Grindavik, prompting residents to evacuate. Lava began flowing from existing and newly opened cracks in a fissure, as emergency crews worked to complete a protective wall of dirt and rock, hoping to direct the flow away from the town’s center. Several houses in Grindavik were burned and crushed before the flow of lava paused once again.
