Previously it was thought that this lava flow ceased before the settlement of Iceland, but this is now not thought to be the case as the coast road (now Route 42) was covered in lava at one stage.
Tidligere mente man, at denne lavastrøm indtraf før bosættelsen af Island, men det anses nu ikke for at være tilfældet, da kystvejen (nu Rute 42) blev dækket i lava på et tidspunkt.
