Pico de Orizaba

Orizaba, Pico de

Stratovolkan · Mexico · 5564 m

Pico de Orizaba (Volcán Citlaltépetl) rises 4,500 m above the Gulf of Mexico coastal plain. Its summit contained a 500-m-wide crater that was 300 m deep at the time of this 1997 photo. It is seen here from the NNE with the Jamapa glacier to the right above the NW-flank peak of Sarcofago (right center). The present summit cone was constructed during the Holocene, overtopping previously collapsed edifices.

Ringkasan geologi

Pico de Orizaba (Volcán Citlaltépetl), México's highest peak and North America's highest volcano, lies at the southern end of a volcanic chain extending north to Cofre de Perote volcano, east of the Serdan-Oriental Basin. The edifice was formed in three stages beginning during the mid-Pleistocene. 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 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. Recorded eruptions have consisted of moderate explosive activity and the effusion of dacitic lava flows. The last known observations of activity were in 1846 CE.

Citlaltépetl, otherwise known as Pico de Orizaba, is an active volcano and the highest volcano in North America, as well as the highest mountain in Mexico and third highest peak in North America, after Denali/Mount McKinley of the United States and Mount Logan of Canada. It rises 5,636 metres (18,491 ft) above sea level in the eastern end of the Trans-Mexican Volcanic Belt, on the border between the states of Veracruz and Puebla. The volcano is currently dormant but not extinct, with the last eruption taking place during the 19th century. It is the second most prominent volcanic peak in the world after Mount Kilimanjaro. Pico de Orizaba is ranked 16th by topographic isolation.
