Geological Summary

The Cerro Mencenares volcanic complex along the Gulf of California is situated at the northern extent of the Loreto Basin, SE of Bahia Concepcion (Dorsey and Umhoefer, 2000). It's eruptive history, which involves three eruptive events, likely played a role in the development of the Loreto Basin. Cerro Mencenares itself is a large stratovolcano; the complex consists of this composite cone and several peripheral centers that cover an area of about 150 km² (Bigioggero et al., 1995). The volcanic products generally consist of Pliocene to lower Pleistocene andesitic to rhyolitic domes, flows, and pyroclastics (San Juanico Unit), along with dacitic and andesitic-basaltic lava flows (Mencenares Unit) (Dorsey and Umhoefer, 2000; Bigoggero et al., 1995). Younger silicic domes and minor basaltic lava flows make up the San Basilio-San Juan Unit (Bigioggero et al., 1995). The volcanic tuffs and breccias on the flanks of the complex are often interbedded with marine mudstones and limestones (Bigioggero et al., 1995; Dorsey and Umhoefer, 2000).

Eruptive History

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

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.

IRIS seismic stations/networks

Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Cerro Mencenares. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice.
