Kirk here. Mt. Aso has erupted. As far as I know, no one has been hurt. The NHK video (in English) relates the current eruption to earlier ones. In 1953, six tourists were killed and over 90 people were injured. Then, the report continues, 12 people were killed in 1958. In 1979, 3 people were killed by ejected rocks. I recommend that you take a look at the video.
