The Krafla central volcano, located NE of Mývatn lake, is a topographically indistinct 9-km-wide caldera that is cut by a N-S-trending fissure system. This view from the south looks toward the center of the caldera with the rhyolitic lava dome of Hlidarfjall on the left and prominent fissures cutting across the caldera at the right.
