Unzendake volcano, which consists of 8 peaks, has erupted so many times since olden times. Fugendake as shown in the first picture is a main peak of this composite volcano. Among many eruptions in Japanese history, the greatest disaster happened here in 1712 involved some 15,000 deaths. The latest disastrous eruption of Fugendake in 1991 is still fresh in our mind. This eruption started in Nov.1990 and finally reached the worst in the following year. Sticky lava formed a huge dome on the summit then it collapsed due to its own weight to become pyroclastic flows at a speed of 100 kilometers an hour. 43 people, most of them are the press, were killed in the incandescent flows. Thereafter, volcanic ashes and rocks remained on the mountainside were washed by heavy rain to hit the many houses near the coast as shown in the second picture. As the locals had left the area in advance, no people were killed by these debris flows.
