The last eruptive episode, which lasted from about 690 years bp until ad 1687, was initiated by a dacitic plinian eruption and was followed by effusive lava-forming eruptions. It is the nation's third highest, after Pico de Orizaba 5,636 m (18,491 ft) and Popocatépetl 5,426 m (17,802 ft). Pico de Orizaba is part of the Trans-Mexican Volcanic Belt that extends roughly east-west across Mexico.

Pico de Orizaba overlooks the valley and city of Orizaba, from which it gets its name. Despite the repetitive history of cone collapse of these volcanoes, only Pico de Orizaba has been subjected to hydrothermal alteration and slope stability studies crucial to understand future potential events of this nature. The volcano is currently dormant but not extinct, with the last eruption taking place during the 19th century. Le pic d'Orizaba ou Citlaltépetl est un volcan du Mexique, à la limite entre les États de Veracruz et Puebla.Culminant à 5 675 mètres d'altitude et situé dans la cordillère néovolcanique, il constitue le point culminant du pays et de cette chaîne de montagnes, mais également le plus haut volcan d'Amérique du Nord ce qui en fait un des sept sommets volcaniques.

Pico de Orizaba Volcano, Mexico, North America - Wikipedia Pico de Orizaba, also known as Citlaltépetl (from Nahuatl citlal(in) = star, and tepētl = mountain), is a stratovolcano, the highest mountain in Mexico and the third highest in North America, after Denali of Alaska in the United States and Mount Logan of Canada. Another eruption about 50,000 years ago caused that to collapse, and Popocatépetl rose from that. Pico de Orizaba (19°02′N, 97°16′W) is a stratovolcano, the highest mountain in Mexico, and the third highest peak in North America. It sits on the border between Veracruz and Puebla. Its height approaches 5,700 m … Pico de Orizaba is part of the Trans-Mexican Volcanic Belt that extends roughly east-west across Mexico. We suggest that the magma reservoir under Pico de Orizaba is stratified. El Pico de Orizaba se formó sobre roca caliza y lutita que datan del período Cretácico, pero básicamente surgió debido a la presión en el magma situado entre los límites de las placas. The name "Iztaccíhuatl" is Nahuatl for "White woman", reflecting the four individual snow-capped peaks which depict the head, chest, knees and feet … First ascent was in 1848 by William F. Raynolds. Towering 18,406 feet (5,610 metres) above sea level, the Pico de Orizaba’s symmetrical snowcapped cone is the third highest peak in North America, after Denali (Mount McKinley) in the U.S. state of Alaska and Mount Logan in Yukon territory, Canada. Pico de Orizaba is one of only three volcanoes in México that continue to support glaciers and is home to the largest glacier in Mexico, Gran Glaciar Norte.Orizaba has nine known glaciers: Gran Glaciar Norte, Lengua del Chichimeco, Jamapa, Toro, Glaciar de la Barba, … Although is known that the Pico de Orizaba had eruptions before the arrival of Spanish Conquistadores in 1521, the Aztec scrolls that detailed on specific dates have been lost. While the volcano is considered dormant at present, geologists continue to investigate the potential hazards associated with a renewal of activity. Orizaba lies at the southern end of a volcanic chain extending north to Cofre de Perote volcano and towers up … This mountain is a stratovolcano and the highest mountain in Mexico, and the third highest in North America.
