Geological summary
The Acoculco volcanic complex lies in the NE part of the Mexican Volcanic Belt, where it intersects the Sierra Madre Oriental volcanic province. The Acoculco caldera complex is located about 80 km WNW of the better known Los Humeros caldera. Three major pyroclastic flows were erupted during the late Pliocene and Pleistocene, associated with two circular depressions 28 x 34 and 16 x 21 km in diameter, respectively. The large rhyolitic Cerros las Tetillas lava dome was emplaced during the early Pleistocene. The latest activity consisted of the extrusion of basaltic lava flows during the late Pleistocene. Thermal areas are located within the caldera complex and on its eastern flanks, and the caldera has been considered as a potential area for geothermal development.

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.
Historical catalogue records
Eruption history
Dates can be approximate, incomplete, or BCE. These are historical catalogue observations, not a statement about present activity.
