Sfondo
The Platanar volcanic center is the NW-most volcano in the Cordillera Central of Costa Rica. The massive complex covers about 900 sq km and is dominated by two largely Pleistocene stratovolcanoes, Platanar and Porvenir. These volcanoes were constructed within the Pleistocene Chocosuela caldera, which may have formed during a major slope failure. The 2183-m-high Cerro Platanar volcano (known locally as Volcán Congo) on the north side of the complex has prehistorical lava flows on its western flanks and is the youngest volcanic center. The highest peak of the complex is 2267-m-high Porvenir volcano, whose summit crater lies 3 km south of Platanar. A thin layer of phreatic ash suggested that an eruption from Platanar occurred within the past few thousand years (Stine and Banks, 1991). The Aguas Zarcas group of nine basaltic cinder cones, located on the north flank of the Platanar-Porvenir complex to as low as 160 m altitude, is in part Holocene in age.---
