Young activity occurred from the La Breña cone only a few thousand years ago. Beschreibung:The Durango volcanic field has erupted basanitic lavas and forms a large undissected lava plain within the Mexican Basin and Range province.Many eruptions in the Durango field display an evolution from predonimantly maar-forming phreatomagmatic eruptions in the past to dominantly magmatic eruptions (strombolian activity) building cinder cones and erupting lava flows in younger times. This suggests a trend of decreasing presence of ground water in the area over time. La Breña-El Jagüey maar complex consists of 2 intersecting maars, the largest of which (La Breña) contains a series of nested cinder cones. The maar complex is one of the youngest eruptive centers of the Durango volcanic field.
