Laki

Laki or Lakagígar (Craters of Laki) is a volcanic fissure in the south of Iceland, not far from the canyon of Eldgjá and the small village Kirkjubæjarklaustur. Lakagígar is the correct name, as Laki mountain itself did not erupt, but fissures opened up on each side of it. Lakagígar is part of a volcanic system centered on the Grímsvötn volcano and including the Þórðarhyrna volcano.^[2][3] It lies between the glaciers of Mýrdalsjökull and Vatnajökull, in an area of fissures that run in a south-west to north-east direction.
