Volcán de Jorcada is an elongated fissure-controlled volcanic massif extending between the Pastos Grandes caldera and Laguna Colorada in Bolivia. More than 50 craters, small stratovolcanoes, and lava domes are located along four fissures covering an area of 230 km2. Eight small andesitic-to-dacitic stratovolcanoes with craters 0.2-1.5 km wide are located along the southernmost fissure. A second fissure, oriented NW-SE and 10 km long, contains ten volcanic centers with craters with widths of 0.2-1.2 km. A third fissure, trending NE, produced seven rhyodacitic lava domes. Activity has migrated to the north, with the youngest fissure, on the NW side of the complex, estimated to be of probable Holocene age (González-Ferrán, 1995). De Silva (2007 pers. comm.) dated this youngest fissure at 95,000 yrs BP. This NW-trending fissure, 7 km long, contains 27 small basaltic-andesite craters.
