La Malinche is an eroded stratovolcano, cut by deep canyons, NE of the city of Puebla. It occupies an isolated position between the Popocatépetl-Iztaccíhuatl and Orizaba-Cofre de Perote volcanic ranges. Much of the andesitic-dacitic volcano was constructed during the Pleistocene, and the summit exhibits evidence of glacial erosion. Although relatively unstudied, research has identified Holocene tephra layers that originated from Volcán la Malinche. Several cones and explosion craters, at least one of Holocene age, are found on the flanks; one of the most prominent of these is the Xalapaxco maar complex on the lower ENE flank. Holocene lahars associated with an eruption about 3,100 years ago reached the Puebla basin and affected communities there.
