Mount Kusatsu-Shirane

Kusatsu-Shiranesan

Stratovolkan · Japan · 2165 m

The summit of Kusatsu-Shiranesan contains three craters with the largest, Yugama, holding the turquoise lake shown here. Rafts of yellow sulfur float on the surface of the acidic lake. This 1977 view looks across the lake from the SW-most crater (Karagama) to the NE-most crater (Mizugama), located beyond the notch to the left. Small-to-moderate phreatic explosions have been recorded from all three craters since the 1800s.

Ringkasan geologi

The Kusatsu-Shiranesan complex, located immediately north of Asama volcano, consists of a series of overlapping pyroclastic cones and three crater lakes. The andesitic-to-dacitic volcano was formed in three eruptive stages beginning in the early to mid-Pleistocene. The Pleistocene Oshi pyroclastic flow produced extensive welded tuffs and non-welded pumice that covers much of the E, S, and SW flanks. The latest eruptive stage began about 14,000 years ago. Historical eruptions have consisted of phreatic explosions from the acidic crater lakes or their margins. Fumaroles and hot springs that dot the flanks have strongly acidified many rivers draining from the volcano. The crater was the site of active sulfur mining for many years during the 19th and 20th centuries.

Ringkasan Inggris

Mount Kusatsu-Shirane is a 2,165 m (7,103 ft) active stratovolcano in Kusatsu, Gunma, Japan. It is called Kusatsu Shirane to differentiate it from the Mount Nikkō-Shirane on the other side of Gunma Prefecture. The summit of Kusatsu-Shirane volcano, located immediately north of Asama volcano, consists of a series of overlapping pyroclastic cones and three crater lakes. The largest of these is Yu-gama, an acidic emerald green lake with rafts of yellow sulfur sometimes seen floating on its surface.
