Popocatépetl(pōpəkăt`əpĕtəl, pōpō'kätā`pətəl) [Aztec,=smoking mountain], volcano, 17,887 ft (5,452 m) high, in the Cordillera de Anáhuac, central Mexico, on the Puebla-Mexico state border; the second highest peak in Mexico. The perpetually snowcapped cone is symmetrical, and the large crater has practically pure sulfur deposits. The ascent, which is fairly easy, was probably first made by Europeans in 1519 by one of Cortés's men. It was quite active during the first two centuries of Spanish colonial times, and from 1919 to 1947 and since 1994 it again experienced a series of eruptions. Its last major Plinian eruption (see volcanovolcano,
vents or fissures in the earth's crust through which gases, molten rock, or lava, and solid fragments are discharged. Their study is called volcanology. The term volcano

(Aztec, “smoking mountain”), a volcano in the Transverse Volcanic Axis of southern Mexico, 65 km southeast of Mexico City. Elevation, 5,452 m. Frequent eruptions occurred in the 16th and 17th centuries. Weak volcanic activity resumed in 1920 but was replaced by strong fumarolic activity that continued until 1927. The slopes of Popocatépetl are covered with oak and pine forests up to an elevation of 3,800 m; they are devoid of any form of vegetation between 3,800 and 4,560 m. Above 4,560 m there are permanent snow and glaciers.
