Geological Summary An extensive Pliocene-Pleistocene volcanic field is located at the northern end of the Atenguillo graben in the Jalisco tectonic block of western México. Pleistocene volcanism has occurred at two locations at the southern and northern ends of the field. Potassium-Argon ages of 0.65 and 0.67 Ma (million years) were obtained from the Las Laja shield volcano at the southern end of the field. Initial phreatomagmatic eruptions at La Laja produced pyroclastic-surge and airfall deposits associated with formation of a tuff ring or tuff cone. Subsequent extrusion of a thick sequence of lava flows formed the symmetrical shield volcano. The flows blocked the Río Atenguillo, forming an ephemeral 20-km-long lake, and the initial flows produced pillow lavas. El Rosario, the northernmost known Pleistocene vent of the Atenguillo graben, forms an alkali-basaltic lava plateau and has a Potassium-Argon age of 0.64 Ma.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Northern Atenguillo. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Northern Atenguillo page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is no Deformation History data available for Northern Atenguillo.

Emission History

Photo Gallery

The terraced Río Ameca valley cuts through flat-lying basaltic lava plateaus of the Northern Atenguillo volcanic field of Pliocene-to-early Pleistocene age. The northernmost of these basaltic plateaus, El Rosario, has been dated at about 640,000 years.

The low-angle La Laja shield volcano lies at the southern end of the Plio-Pleistocene Northern Atenguillo volcanic field in the Jalisco tectonic block of western México. La Laja was dated at about 660,000 years. Initial phreatomagmatic eruptions at La Laja produced pyroclastic-surge and airfall deposits. These were followed by the extrusion of a thick sequence of lava flows that built the symmetrical shield volcano. The flows blocked the Río Atenguillo, forming an ephemeral 20-km-long lake.

Cerro La Cienega is a broad andesitic shield volcano that lies east of the Atenguillo river near the center of the Northern Atenguillo volcanic field. It is one of three Pliocene andesitic centers in the volcanic field, which also includes the La Laja shield volcano and the El Rosario lava plateau of Pleistocene age.

WOVOdat    Single Volcano View    Temporal Evolution of Unrest    Side by Side Volcanoes	WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore. GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.
