Overview

Two small eruptive vents that produced lava flows lie about 3 km apart in the Callejón de Tilocálar area. Lava flows overlie Pliocene ignimbrites and were considered to be of Pleistocene-Holocene age by González-Ferrán (1995). The larger feature, Tilocálar Sur, lies about 3.

5 km SW of Tilocálar Norte. Four basaltic andesite to andesitic lava flows originated from Tilocálar Sur, and an explosion crater lies a kilometer to the south. The Tilocálar Norte lies near the eastern wall of the Callejón de Tilocálar and produced lava flows that traveled primarily to the north.

Regional Volcanic Activity

The South America Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

The Tilocalar volcanic center is shown here in this 25 November 2019 Sentinel-2 satellite image (N is at the top), with Tilocalar Norte near the center of the image and Tilocalar Sur to the SW. Tilocalar Norte erupted a single 4.3-km-long lava flow while Tilocalar Sur produced four lava flows. They overlie the Talabre ignimbrite.
