Mt. Ontake, a popular tourist spot lying 200 kilometers from Tokyo and containing five beautiful crater lakes, was in the news recently for some tragic reasons. On Saturday the 27th of September the volcano erupted, causing more than 30 deaths. Luckily some hikers managed to escape, and caught the amazing event on film as they were overtaken by a huge cloud of ash.
