The Olot volcanic field (also known as the Garrotxa volcanic field) occupies the NE corner of Spain south of the Pyrenees Mountains about 90 km NNE of Barcelona. The Olot volcanic field consists of a large number of strombolian pyroclastic cones and associated alkali basaltic lava flows and is part of the NE Volcanic Province, which includes the Ampurdán and Selva areas to the SE. The pyroclastic cones are preferentially located at the intersection of E-W and NW-SE faults that cut sedimentary and metamorphic basement rocks. The latest dated eruption at Olot occurred during the early Holocene, and stratigraphic evidence suggests that more recent eruptions have occurred.

The Global Volcanism Program is not aware of any Holocene eruptions from Olot Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Olot Volcanic Field 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 Quaternary Olot volcanic field (also known as the Garrotxa volcanic field) lies in NE Spain around the city of Olot (the light-colored area near the center of this NASA Landsat image (with north to the top). Pyroclastic cones cover broad areas north, east, and south of the city. A voluminous alkali basaltic lava flow underlies the less forested area SE of Olot. The pyroclastic cones are preferentially located along faults cutting underlying sedimentary and metamorphic basement rocks.

The forested Volcà Montolivet cinder cone rises above the orange-roofed buildings of the city of Olot, as seen from the Volcà Montsacopa cinder cone to the NE. The cone is part of a large volcanic field named after the city and occupies the NE corner of Spain south of the Pyrenees Mountains about 90 km NNE of Barcelona. The latest dated eruption at Olot (also known as the Garrotxa volcanic field) occurred during the early Holocene, and stratigraphic evidence suggests that more recent eruptions have occurred.
