Lava lake volcanic fissures. Glowing pattern of fissures in the crust on the surface of the lava lake of the Erta Ale basaltic shield volcano, located in the Danakil depression, Ethiopia. This lava lake is part of the summit caldera. Convective currents in the lava create these fissures, similar to the process of plate tectonics. Photographed at dusk.
