Geological summary
The Acatlán volcanic field, located SW of La Primavera caldera, is a group of andesitic cones, rhyolitic lava domes, and lava flows associated with a caldera system. The Acatlán Ignimbrite is a compositionally zoned rhyolitic-to-andesitic tuff that covers an area of about 150 km2. The ignimbrite overlies andesitic breccias dated at 0.65 million years. Following eruption of the ignimbrite, a series of rhyolitic and dacitic lava domes and andesitic cinder cones and lava flows were erupted throughout the Acatlán volcanic field.

Weekly volcanic activity reports
Smithsonian/USGS weekly reports are selective and preliminary. They are not a comprehensive list of all eruptions or volcanic activity.
No weekly report appears on this page. Absence from the weekly report does not establish an absence of volcanic activity.
