Acatenango Location: 14.501° N, 90.876° W Elevation: 3.976 m The Fuego-Acatenango massif comprises a string of  five or more volcanic vents along a north-south trend  that is perpendicular to that of the Central American  Volcanic Arc in Guatemala. From north to south, known  centers of volcanism are Ancient Acatenango,  Yepocapa, Pico Mayor de Acatenango, Meseta, and  Fuego. Volcanism along the trend stretches back more  than 200,000 years. Although many of the centers have  been active contemporaneously, there is a general  sequence of younger volcanism, from north to south  along the trend. This massive volcano complex towers  more than 3,500 metres above the Pacific coastal plain  to the south and 2,000 metres above the Guatemalan  Highlands to the north. The volcano complex comprises remnants of multiple eruptive centers, which  periodically have collapsed to form huge debris avalanches. The largest of these avalanches  extended more than 50 kilometres from its source and covered more than 300 square kilometres. The  only known historical eruption of Acatenango volcano occurred in the 20th century, between 1924 and  1927 from just north of the summit peak (Pico Mayor) and again in December 1972 from the saddle  between Yepocapa and Pico Mayor. These phreatic explosions generated ballistic volcanic bombs  that fell near the summit craters and fine volcanic ash that fell up to 25 km away. In prehistoric time,  Acatenango has erupted explosively to form widespread fall deposits, hot pyroclastic flows and lava  flows. There have been numerous eruptions during the past 80,000 years from vents along the  massif. The most recent explosive eruptions of Acatenango occurred 1,900 years ago (Pico Mayor),  2,300 years ago (Pico Mayor) and about 5,000 years ago (Yepocapa). If such eruptions were to recur, many people and costly infrastructure would be at risk. (Wikipedia)  Photo: Rolf Cosar Photo: Rolf Coisar Photo: Rolf Cosar Photo: Rolf Cosar HOME
