The winners of the National Geographic Travel Photographer of the Year Award have been unveiled, with the top prize going to Mexican lensman Sergio Tapiro Velasco. The image, titled The Power of Nature (pictured above), captured stunning lightning activity over an active volcano. "When I looked on the camera display, all I could do was stare," said Velasco. "What I was watching was impossible to conceive, the image showed those amazing forces of nature interacting on a volcano, while the lightning brightened the whole scene. It's an impossible photograph and my once in a lifetime shot that shows the power of nature."

While the grand prize included a 10-day trip for two to the Galapagos Archipelago with National Geographic Expeditions as well as Dhs9,200 in prize money, the second and third winners received Dhs2,700 and Dhs1,800 respectively.
