Volcanic activity and geology

The Acatenango Volcano is 3976 meters high (about 13,000 feet). Within its historical activity there were small eruptions that released ash and gases from 1924 to 1927 and in 1972. The Acatenango Volcano has two peaks, identified as the Pico Mayor and the Yepocapa, although the latter is also known as the Three Sisters or Three Mary’s.  This volcano collapsed to the south about 43,000 years ago, forming an avalanche of rocks, which covers an extensive area of ​​the coastal plain of the Pacific Ocean. The build-up of the peak called Yepocapa was completed around 20,000 years ago. After growth, the highest point or cone, the Pico Mayor, was produced. It is believed that it also had activity in 1661, although only with smoke (Main Volcanoes of Guatemala, s.f.) (Information described in WikiGuate, 2018).


Cold fronts, snow and hail

Snowfall has recently been documented in Acatenango volcano and Fuego volcano, a phenomenon that is not common. The most recent was registered on November 23, 2017; being the third occasion that occurred, after those reported on April 21 and August 9, 2017. The snowfalls have been caused by the presence of cloudiness and rains that combined with the cold temperatures of a cold front (Information based on reports by Glen García, 2017 and the blog El Clima en Guatemala, 2017).
