Rincon de la Vieja

複成火山 · Costa Rica · 1729m

Part of the complex summit region of Rincón de la Vieja, the largest volcano in NW Costa Rica, is seen here from the north. Steam rises from the lake-filled Cráter Activo to the left, ENE of the Von Seebach cone (right). Laguna Fria (far-left) is not a crater lake, but a freshwater lake that formed between overlapping cones of the summit complex, which extends east and west beyond this area. Frequent eruptions from Cráter Activo have left surrounding terrain unvegetated.

地質学的概要

Rincón de la Vieja is a volcanic complex in the Guanacaste Range of NW Costa Rica. Sometimes referred to as the Rincon de la Vieja-Santa María Volcanic Complex, it consists of a slightly arcuate 20-km-long ridge of 12 craters and pyroclastic cones constructed within the 15-km-wide early Pleistocene Guachipelín caldera, whose rim is exposed on the south side. Sometimes known as the "Colossus of Guanacaste," it has an estimated volume of 130 km3 and contains at least nine major eruptive centers. The Santa María cone, the highest peak of the complex, is located on the E side of the ridge and has a lake within the 400-m-diameter crater. A Plinian eruption producing the 0.25 km3 Río Blanca tephra about 3,500 years ago was the last major magmatic eruption. All subsequent eruptions, including numerous reported eruptions possibly dating back to the 16th century, have been from the active crater, near the center of the complex, with an acidic 300-m-diameter lake.
