<p><span>Mt. Ontake volcano erupted at 11:52 on September 27, 2014, claiming the lives of at least 58 hikers. This eruption was the worst volcanic disaster in Japan since the 1926 phreatic eruption of Mt. Tokachidake claimed 144 lives (Table </span><span class="InternalRef"><a href="http://earth-planets-space.springeropen.com/articles/10.1186/s40623-016-0548-4#Tab1" data-mce-href="http://earth-planets-space.springeropen.com/articles/10.1186/s40623-016-0548-4#Tab1">1</a></span><span>). The timing of the eruption contributed greatly to the heavy death toll: near midday, when many hikers were near the summit, and during a weekend of clear weather conditions following several rainy weekends. The importance of this timing is reflected by the fact that a somewhat larger eruption of Mt. Ontake in 1979 resulted in injuries but no deaths. In 2014, immediate precursors were detected with seismometers and tiltmeters about 10 min before the eruption, but the eruption started before a warning was issued.</span></p>
