A brave photographer managed to get within metres of an active volcano despite it spewing out lava waves over 140 metres high. Silhouetted against a fiery fountain of red, Icelandic photographer, Tómas Freyr Kristjánsson, 37, braved blistering temperatures to get as close the volcano as possible. Although very few were brave enough to get so close, Tómas managed to photograph nearby tourists to give some scale to the spraying molten rock, including that of a nearby motorcyclist.

A member of the United States Naval Academy freshman class crawls through trenches at the wet and sandy station during the annual Sea Trials training exercise at the U.S. Naval Academy on May 13, 2014 in Annapolis, Maryland. For 14 hours, the United States Naval Academy freshman class, also known as Plebes, worked as a team to complete many grueling physical and mental challenges that help prepare them for real-world experiences and reinforce leadership, bonds, trust, and teamwork. Of the challenges, they endured: a two-mile regimental run, ground fights, water tactics, aquatics challenges, and survival skills, amongst many others. (Photo by Patrick Smith/Getty Images)
