Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Mascota Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Mascota Volcanic Field 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 forested lava flow extending across the valley floor in the center of the photo is from Volcán Malpais in the Mascota Volcanic Field, and may be only a few thousand years old. The flow is seen here looking west across the graben floor from Volcán Molcajete.

Part of the Mascota Volcanic Field in the Jalisco tectonic block east of Puerto Vallarta appears in this aerial view from the south. The scoria cone in the center is Volcán Molcajete, which along with the smaller Volcán Novillero to its left. The forested lava flow at the left side of the valley originated from Volcán Malpais. It is located at the valley margin above and left of Volcán Novillero.

The summit ridge of flat-topped Volcán Molcajete (left) is at the level of the horizon in this view from the SW. Molcajete, referring to stone bowls used for grinding grains, is a common name applied to scoria cones with well-preserved craters. Volcán El Tecomate is the steep-sided scoria cone to the right. These two cones are located NE of the town of Mascota and are part of a Pleistocene-to-Holocene volcanic field in the Jalisco block, which is being underthrust by the eastward-subducting Rivera tectonic plate.

Volcán el Puerto (left) and Volcán Embarcadero (right) are seen from the east across fields of the Mascota graben. Both cones have craters that open towards the east. They are in the NW side of the Mascota Volcanic Field and erupted near the western base of the graben walls, which in this view consists of metamorphic rocks and elsewhere of Cretaceous tuffs. The Mascota graben here is about 5 km wide.

A group of scoria cones and lava domes are located near the town of Mascota, east of Puerto Vallarta. Steep-sided Tecomate lava dome (near the center) and Molcajete scoria cone (right center) are seen here from the NW. A recent eruption produced a lava flow from Volcán Malpais, north of Mascota.

Photo by Jim Luhr, 1985 (Smithsonian Institution).
Volcán Tecomate (left of center) and flat-topped Volcán Molcajete (to the right), seen here from the NW, are two of the scoria cones and domes of the Mascota Volcanic Field. These are part of a group cinder cones and lava flows located within the Talpa and Mascota grabens near the town of Mascota, east of Puerto Vallarta.
