Pico de Orizaba volcano (Volcán Citlaltépetl) is a large active stratovolcano, Mexico's highest mountain and the highest volcano of North America. It is located at the southern end of Citlaltépetl–Cofre de Perote Volcanic Range, and the only volcano in this area with historic activity.
Historical eruptions have consisted of moderate explosive activity and the effusion of dacitic lava flows. The latest eruption of the volcano were in 1545, 1566, 1630 and 1687.

Introduction
Pico de Orizaba volcano was formed in 3 stages beginning during the mid-Pleistocene. Orizaba lies at the southern end of a volcanic chain extending north to Cofre de Perote volcano and towers up to 4400 m above its eastern base. Construction of the initial Torrecillas and Espolón de Oro volcanoes was contemporaneous with growth of Sierra Negra volcano on the SW flank and was followed by edifice collapses that produced voluminous debris avalanches and lahars. The modern Citlaltépetl volcano was constructed during the late Pleistocene and Holocene of viscous andesitic and dacitic lavas, forming the current steep-sided cone. Repetitive explosive eruptions beginning during the early Holocene accompanied lava dome growth and lava effusion.Pico de Orizaba Photos
