Geological Summary

Volcán Tepetiltic is an andesitic and dacitic stratovolcano truncated by an elliptical 5 x 2.5 km caldera that contains a lake at its NE corner. The caldera, with steep-sided walls elongated NE-SW, originated during a major rhyodacitic eruption that produced Plinian-airfall, pyroclastic-flow, and pyroclastic-surge deposits around the volcano. Caldera collapse was closely followed by emplacement of lava domes on the eastern flank. Two andesitic domes were later emplaced on the caldera floor, and chemically unrelated flank cinder cones were erupted.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Tepetiltic. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Tepetiltic page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Photo Gallery

The oval-shaped, 5 x 2.5 km Tepetiltic caldera, seen here from the shore of a lake that occupies the older NE side of the caldera, was formed during two eruptive episodes that produced voluminous rhyodacitic airfall tephra and ashflows. Formation of the compound caldera was closely followed by emplacement of two rhyodacitic lava domes on the eastern flank. The low forested hill at the far side of the lake is a lava dome extruded near the intersection of the two calderas. A second dome was emplaced to the left on the floor of the higher SW caldera.

Volcán Tepetiltic is an andesitic and dacitic stratovolcano truncated by an elliptical, 5 x 2.5 km caldera that contains a lake at its NE corner. The compound caldera, seen here from the NE, was formed during major rhyodacitic eruptions that were closely followed by emplacement of lava domes on the eastern flank. A permanent caldera lake (center) occupies the lower NE caldera floor. The small forested lava dome beyond the caldera lake was emplaced near the intersection of the two calderas.

The irregular ridge on the horizon is the SE rim of the compound 5-km-wide Tepetiltic caldera. The NE caldera was offset from the center of the stratovolcano and its rim is lower to the NE (right). The flanks of the andesitic-dacitic stratovolcano are blanketed by deposits of rhyodacitic ash and pumice from the caldera-forming eruptions. Cinder cones on the NW and SE flanks of the volcano erupted alkalic lava flows.

The flat-topped rhyolitic Los Ocotes lava dome (center) was erupted on the southern flank of Tepetiltic volcano about 100,000 years ago and is the youngest product of that complex. Extrusion of the dome blocked drainages to form Laguna San Pedro, out of view to the left. The rim of Tepetiltic caldera forms the right horizon. Los Ocotes is seen here from the SE along Highway 15 where it crosses the blocky andesitic El Ceboruco lava flow in the foreground, which traveled 8 km from Ceboruco volcano.

   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.
