A few unlucky hikers were caught in one hell of a big surprise as the volcanon on which they were traveled erupted suddenly, Sept. 14.
Thankfully, no injuries were reported from enormous burst of black smoke and ash that rose up to 1.2 miles in the air.
According to The Guardian:
The 1,592-metre (5,222ft) high Mount Aso is one of the most active peaks in Japan but also a popular hiking spot. There were a handful of people at a parking lot near the peak but they were being evacuated safely, officials said on Monday. They said the eruption had come without warning.
The Guardian was also kind enough to provide a handy map so you know where this happened:

There is a nearby nuclear plant, but officials have said that it remains unaffected by the surprise eruption.
