This Month in Photo of the Day: Nature and Weather Photos

The volcano Eyjafjallajökull, in Iceland, just before dawn on April 23, 2010: The worst is over. Lava flows freely. Earlier, as it punched through the ice cap, it triggered a meltwater flood that destroyed roads and farms, and a steam explosion that hurled ash into the stratosphere, stopping air traffic for a week.
