Pacaya is the largest post-caldera volcano, and has been one of Central America's most active volcanoes over the last 500 years. Īfter the last caldera-forming eruption 23,000 years ago, several smaller vents within and around the caldera have seen eruptive activity. This caldera has been the source of at least nine very large explosions over the past 300,000 years, erupting a total of about 70 cubic kilometres (17 cu mi) of magma. Pacaya lies on the southern edge of a sizable volcanic caldera formed in the Pleistocene age which contains Lago de Amatitlán. The Pacaya volcano is a part of the Central American Volcanic Arc, a chain of volcanoes stretching from the northwest to the southeast along the Pacific coast of Central America, formed by the tectonic subduction of the Cocos Tectonic Plate beneath the Caribbean Plate. Villagers near Pacaya ignored an evacuation request as the volcano threw ashes into the air in March 2021. Volcano Boarding is also practiced on the craters of Pacaya. The volcano sits inside the Escuintla Department. It lies 30 kilometers (19 miles) southwest of Guatemala City and close to Antigua. It is even the home to the popular Guatemala Impact Marathon which pioneered the use of a running route across the lava field created by the 2010 eruption and supports the local communities through runners endeavouring to complete the challenge.
Much of its activity is Strombolian, but occasional Plinian eruptions also occur, sometimes showering the area of the nearby Departments with ash. After being dormant for over 70 years, it began erupting vigorously in 1961 and has been erupting frequently since then. It rises to an elevation of 2,552 metres (8,373 ft). Pacaya is an active complex volcano in Guatemala, which first erupted approximately 23,000 years ago and has erupted at least 23 times since the Spanish conquest of Guatemala.
