A lava flow descends the NE flank of Villarrica volcano in 1984. A small lava lake at the NNE side of the summit crater fed lava flows through a notch in the crater rim left by the 1971 eruption. The lava initially flowed down the summit icefield and then burrowed under the glacier. The flow emerged onto the surface on November 13, producing a 3-km-long avalanche of lava blocks, ice, and snow.
