Holuhraun lava field in Iceland, captured by the Advanced Land Imager on NASA's Earth Observing-1 satellite at 10:00 a.m. local time, on November 5, 2016. The 2014-15 eruption was the largest basaltic lava flow in Iceland since 1783-84, spreading across 84 square kilometers (32 square miles). More than a year after the eruption, the lava is still too warm to accumulate snow. The round feature above the lava is Askja caldera. The photo has been edited to correct for the low angle of the sun.
