May 2014 Viewer's ChoiceThe photo above shows a recent eruption of Mount Yasur in Vanuatu, as observed during my last expedition there in November of 2013. Our team camped approximately 300 ft (100 m) from the summit for five days, collecting lava samples from previous eruptions. The shock wave from this discharge almost flattened the tents. Though standing only 1,184 ft (361 m) above sea level, Mount Yasur (a stratovolcano) has been in a nearly constant state of eruption for over 800 years. Note the glowing lava bomb on the summit's flank at upper right -- estimated to be 12 ft (4 m) in length. Photo taken on November 3, 2013.
