Philippine tour guide Roel Llarena recalled Wednesday how a mountain hike turned into a nightmare when the volcano he was climbing began spewing out giant rocks, killing five of his companions.
Mount Mayon volcano spews a thick column of ash 500 metres (1,600 feet) into the air, as seen from the city of Legazpi, southeast of Manila, in a photo taken on May 7, 2013 and released by the Philippine Institute of Volcanology and Seismology.
"I stood there frozen. I couldn't believe what was happening, I didn't know what to do. It was like a scene from hell," he told AFP, after surviving the giant ash explosion at Mayon volcano on Tuesday.
