A group of climbers filmed themselves running for their lives after being caught on a volcano when it unexpectedly erupted. <br /> <br />Several climbers were scaling Mount Ontake in Japan this morning when it suddenly erupted, injuring at least eight people and leaving another 250 stranded near the peak, Japan Times reports. <br /> <br />One group were filming as they tried to flee the approaching ash cloud before it engulfed them. <br /> <br />The hiker who posted the video said the team managed to find shelter in a nearby hut, and local officials report that no one was killed due to the eruption. <br /> <br />However several commenters have expressed fear that the thick cloud of hot ash could do serious damage to hikers’ lungs. <br /> <br />Huichi Mukai, who runs a mountain lodge near the summit of Mount Ontake, said: ‘There was a thunderlike noise and the sky became dark because of the smoke. <br /> <br />‘There is now 15cm of ash on the ground.’ <br /> <br />Mount Ontake, which sits in the centre of the Japanese islands, roughly 200km West of Tokyo, experienced its last major eruption in 1979 and is Japan’s second largest volcano.
