Lava Flow on Mawson Peak, Heard Island. The images show proof of an eruption on Mawson Peak. By 2013.04.07 Mawson's steep-walled summit crater had filled, and a trickle of lava had spilled down the volcano’s southwestern flank. On April 20, the lava flow remained visible & had widened slightly just below the summit. Natural-color images were collected by the Advanced Land Imager (ALI) on the Earth Observing-1 (EO-1) satellite. (Image Credit: NASA Earth Observatory)
