Introduction Mount Fuji is the tallest mountain in Japan standing at 12385 feet (3776 m) and is located on the main island Honshu 62 miles (100 km) southwest of Tokyo. It has a 78 miles circumference and a 25-30 miles in diameter around the base with a 1600 feet diameter crater. The mountain is surrounded by five lakes, Lake Kawaguchiko, Lake Yamanaka, Lake Saiko, Lake Motosuko, Lake Shojiko. The conic stratovolcano lies above a complex tectonic area known as the “Fossa Magna” which is the collision of the Philippine Sea plate with the Eurasian plate in the North and with the North American plate in the northeast. This junction is called the Fuji triple junction. There are different mythology related to Mount Fuji according to Buddhist and…show more content…
This particular earthquake was the largest recorded earthquake for Japan prior to 2011 earthquake. 49 days after the Hoei earthquake, on 16 December 1707, Mount Fuji erupted from three vents located on its southeast flank [Tsuya, 1955]. This particular eruption was a plinian eruption that produced 0.7 km^3 of tephra [Miyaji and Koyoma, 2007], and the emission was of mixed and mingled andesitic and dacitic tephras that was then followed by basaltic tephra [Tsuya, 1955]. According to Chesley (2012), the conduit was opened and the basaltic magma was pushed out of the chamber by unclamping of the deeper dike along with compression of the basaltic magma chamber. This basaltic magma then moved up the dike from the basaltic chamber 20 km deep into the andesitic and dacitic magma chambers creating magma mixing and rapid vesiculation. The magma then migrated from the 8 km deep chambers to the surface. The mixing can be found in the chemically zoned tephra deposits that include banded pumice of andesitic and dacitic composition [Yoshimoto, 2004]. Historical reports show that seismic activity started on the south flank of Fuji on 3 December 1707, 36 days after the Hoei earthquake, suggesting that magma migration started on or before 3 December 1707 and continued until the eruption on 16 December 1707 [Tsuya, 1955].
