Neighboring Volcanoes~

Mount Fuji is composed of not one, but three different volcanoes. Mt. Fuji was created by a series of volcanic activity cauesd by Ko-Mitake (small mitake), Ko-Fuji (old Fuji) and Shin-Fuji (new Fuji) volcanoes. The Ko-Fuji volcano formed the base of the current Mt. fuji and has been dormant since 100 thousand years ago. The Ko-Fuji volcano was active betwee 100 thousand and 10 thousand years ago. Mount Fuji is a relatively young volcano and aquired its present shape about 5000 years ago. Shin-Fuji is responsible for Mt. Fuji's shape to this day. Shin-Fuji started to erupt about 10 thousand years ago and repeatedly erupted over 100 times during a span of about 10 thousand years. Although Mt. Fuji has been sleeping since its last eruption on November 24, 1707, geologists still regard it as an active volcano.
