Saitama, Tochigi, Ibaraki and Lake Hamana when the sky is clear. It has been photographed from space during a space shuttle mission. Climate The summit of Mount Fuji has a tundra climate (Köppen climate classification ET). The temperature is very low at the high altitude, and the cone is covered by snow for several months of the year. The lowest recorded temperature is recorded in February 1981, and the highest temperature was recorded in August 1942. Geology Mount Fuji is located at a triple junction trench where the Amurian Plate, Okhotsk Plate, and Philippine Sea Plate meet. These three plates form the western part of Japan, the eastern part of Japan, and the Izu Peninsula respectively. The Pacific Plate is being subducted beneath these plates, resulting in volcanic activity. Mount Fuji is also located near three island arcs: the Southwestern Japan Arc, the Northeastern Japan Arc, and the Izu-Bonin-Mariana Arc. Mt. Fuji's main crater is in diameter and in depth. The bottom of the crater is in diameter. Slope angles from the crater to a distance of are 31°–35°, the angle of repose for dry gravel. Beyond this distance, slope angles are about 27°, which is caused by an increase in scoria. Mid-flank slope angles decrease from 23° to less than 10° in the piedmont. Scientists have identified four distinct phases of volcanic activity in the formation of Mount Fuji. The first phase, called Sen-komitake, is composed of an andesite core recently discovered deep within the mountain. Sen-komitake was followed by the "Komitake Fuji", a basalt layer believed to be formed several hundred thousand years ago. Approximately 100,000 years ago, "Old Fuji" was formed over the top of Komitake Fuji. The modern, "New Fuji" is believed to have formed over the top of Old Fuji around 10,000 years ago. Pre-Komitake started erupting in the Middle Pleistocene in an area north of Mount Fuji. After a relatively short pause, eruptions began again which formed Komitake Volcano in the same location. These eruptions ended 100,000 years ago. Ashitake Volcano was active from 400,000 to 100,000 years ago, and is located southeast of Mount Fuji. Mount Fuji started erupting 100,000 years ago, with Ko-Fuji (old-Fuji) forming 100,000 to 17,000 years ago, but which is now almost completely buried. A large landslide on the southwest flank occurred about 18,000 years ago. Shin-Fuji (new-Fuji) eruptions in the form of lava, lapilli and volcanic ash, have
