Two small stratovolcanoes, the Volcánes de Tilocálar, lie about 3 km apart in the Callejón de Tilocálar area. The volcanoes overlie Pliocene ignimbrites and were considered to be of Pleistocene-Holocene age by González-Ferrán (1995). The larger volcano, Tilocálar Sur, lies about 3.5 km SW of the northern volcano, Tilocálar Norte. Four basaltic-andesite to andesitic lava flows originated from 3116-m-high Tilocálar Sur, and an explosion crater lies a kilometer to the south. The 3040-m-high Tilocálar Norte lies near the eastern wall of the Callejón de Tilocálar and produced lava flows that traveled primarily to the north.

The Global Volcanism Program is not aware of any Holocene eruptions from Tilocalar. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tilocalar 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.

Two small stratovolcanoes, the Volcánes de Tilocálar (left of center at the bottom of this Landsat image), lie about 3 km apart in the Callejón de Tilocálar area. The volcanoes overlie light-colored Pliocene ignimbrites. The larger volcano, 3116-m-high Tilocálar Sur, lies about 3.5 km SW of the northern volcano, Tilocálar Norte and produced four basaltic-andesite to andesitic lava flows. Tilocálar Norte produced elongated lava flows that traveled primarily to the north.

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.
