Mt. Fuji Fun Facts Mt. Fuji at sunrise from Lake Kawaguchi Elevation: 3,776 meters (12,388 feet) Type: Stratovolcano (dormant) Easiest Route: Hike Last eruption: 1707 Location: Honshu, Japan First ascent: 663 by an anonymous monk Coordinates: 35°22′N,138°44′E Temperature: -18 to +8 degrees Celsius

Guess What? More Fun Facts!! Mt. Fuji is not only a single structure, the volcano is actually a group of "superposed" cones. (Fuji consists of 3 different volcanoes) Mt. Fuji is famous for its perfectly symmetrical cone. The Japanese call the mountain Fuji-yama or Fuji-san and it is considered a sacred mountain because the climbing of it is a religious practice.

Map and Lakes Mt. Fuji consists of 5 surrounding lakes: Lake Motosuko- deepest lake Lake Shojinko- smallest lake Lake Kawaguchi- accessible and commercialized Lake Yamanako- recreational Lake Subarshiri

Mt. Fuji: A Stratovolcano Stratovolcanoes make up 60%, the largest percentage, of the earth's individual volcanoes. Most stratovolcanoes are characterized by eruptions of andesite and dacite. However, unlike most stratovolcanoes Mt. Fuji is mostly composed of Basalt. These two rocks make up lavas that are cooler, thicker, and more sticky than basalt. Andesite (top) & Basalt (bottom)

Volcanic Eruptions These thicker lavas, andesite and dacite, allow gas pressures to build up to high levels which results in explosive eruptions.

The present Fuji (younger Fuji Volcano) Mt. Fuji is comprised of three different volcanoes that lie one on top of the other: Komitake Ko-Fuji (older Fuji Volcano) The present Fuji (younger Fuji Volcano) Ko-Fuji (older Fuji Volcano) is newly erupted and on the south side of Mt. Komitake. (See Below) The younger, and present day, Fuji Volcano erupted 10 thousand years ago and expanded from the central crater of Ko-Fuji. (See Above) Mt. Komitake first errupted 700 thousand years ago and forms the northern part of Mt. Fuji. (See Above)

Mt. Fuji’s Eruptions Komitake became an active volcano in the middle Pleistocene. The eruption consisted of andesite lava flows. The younger Fuji Volcano varied in it’s type of eruptions over the past 11 thousand years.
