Geology
editMount Masurai is part of the greater Barisan Mountains, which formed due to offshore subduction of the Indo-Australian Plate beneath the Sunda Plate along the Sunda megathrust. The volcanic comples is situated in the Sungai Penuh pull-apart basin; caused by offsets along two segments of the Great Sumatran fault. In the southern section of the basin, closer to Mount Masurai, the basin becomes wider.[2]
Mount Matsurai contains two crater lakes; Kumbang Lake and Merbuk Lake; near the summit cone. The summit cone occupies the western remnant of a half-caldera, 7 km in diameter. The rim of the half-caldera is at an altitude of 2,000 m (6,600 ft)–2,250 m (7,380 ft). A third lake, Blue Lake, located in the caldera, is thought to be remnants of a parasitic eruption; one of many around the area.[3]
Flora
editTwo species of tropical carnivorous pitcher plants; Nepenthes spathulata and Nepenthes singalana notably overlap each other. The plants, which cannot be definitively assigned to either appear intermediate in form between these two species. It was discovered by botanist Charles Clarke, and written in his monograph Nepenthes of Sumatra and Peninsular Malaysia.[4]
Climbing
editKumbang Lake is a popular feature of the volcano, often visited by climbers on their way to the summit.[5]
