Recent volcanic activity reminds us of the 2010 disaster. The volcano in southern Iceland's Eyjafjallajokull glacier sends ash into the air just prior to sunset ON Friday, April 16, 2010. Thick drifts of volcanic ash blanketed parts of rural Iceland on Friday as a vast, invisible plume of grit drifted over Europe, emptying the skies of planes and sending hundreds of thousands in search of hotel rooms, train tickets or rental cars.
