Geological Background

Volcán Laguna Mariñaqui is a minor volcanic center that lies SSE of Copahué volcano and ENE of Tolguaca volcano. It consists of two craters of Holocene age (González-Ferrán, 1995) 2 km apart along a NE-trending fault that produced andesitic pyroclastic material and lava flows with columnar jointing. Cerro Chapulul is a 2143-m-high Holocene cinder cone in this area of the Malleco province of central Chile (Moreno 1985, pers. comm.). The cone occupies a plateau ranging from 2000-2300 m in altitude.

The Global Volcanism Program is not aware of any Holocene eruptions from Laguna Mariñaqui. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Laguna Mariñaqui page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features.
