Volcán Lomas Blancas is a small shield-like stratovolcano of late-Pleistocene to Holocene age (Moreno and Naranjo, 1991) located about 15 km SE of Nevado de Longaví volcano. A 2.3-km-wide caldera, possibly formed by edifice collapse, is open to the SE. Basaltic-andesite aa lava flows extend 7 km from the collapse scarp. The basaltic central cone rises about 500 m to an elevation of 2268 m. Much of the volcano is covered by pumice deposits that probably originated from Nevado de Longaví.
The Global Volcanism Program is not aware of any Holocene eruptions from Lomas Blancas. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Lomas Blancas 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. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.
|The small light-brown area at the center of this NASA International Space Station image (with north to the bottom right) is Volcán Lomas Blancas. This small shield-like 2268-m-high stratovolcano of late-Pleistocene to Holocene age is located about 15 km SE of snow-capped Nevado de Longaví volcano (right-center). A 2.3-km-wide caldera, possibly formed by edifice collapse, can been seen opening to the SE. Pumice deposits probably originating from Nevado de Longaví blanket the volcano. The crescent-shaped lake at the upper left is Laguna del Dial.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
