The silicic Hrafntinnuhraun eruption occurred in about 877 CE, producing about 0.18 km3 of lava and 0.4 km3 of tephra. An eruption column of up to 20 km high was associated with this Plinian eruption. The Hrafntinnuhraun lava flow stretches from the bottom left to top right in this image, with a stream running around its base on the left reflecting the sun.
