Mount Nasu

Nasudake

Estratovolcán · Japan · 1915 m

A line of hikers at the lower left walk along a trail below the summit of Chausudake, the active cone of the Nasudake volcanic complex. This volcano group consists of a N-S-trending cluster of cones and lava domes at the N end of the Kanto Plain. Chausudake is a young cone that formed about 16,000 years ago. Six eruptions took place in 1408-1410 CE, when the youngest summit lava dome formed; additional smaller phreatic eruptions have occurred since then.

Resumen geológico

The Nasudake volcanic group consists of a N-S-trending cluster of stratovolcanoes and lava domes at the north end of the Kanto Plain. Volcanic activity dates back about 500,000 years. Growth of three large basaltic-to-dacitic stratovolcanoes, each lasting about 200,000 years, was followed by construction of three smaller andesitic stratovolcanoes, Asahidake, Futamatayama, and Chausudake. Activity during the last 55,000 years included the collapse of Asahidake volcano about 30-40,000 years ago, producing the massive Ofujisan debris-avalanche deposit, which covers a broad area SE of the volcano. The youngest volcano, Chausudake, began forming about 16,000 years ago. Six magmatic eruptions took place since then, the latest in 1408-1410 CE, when the Chausudake summit lava dome formed. These eruptions produced block-and-ash flows and concluded with the extrusion of lava flows. Smaller phreatic eruptions have occurred every few hundred years during the past 5,000 years.
