Global Volcanism Program | Image GVP-11130
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.
