Amatitlán Caldera |
The Amatitlán area has been identified by Koch and McLean (1975) and Wunderman and Rose (1984) as the source of several voluminous silicic tephras in central Guatemala. At least nine major pyroclastic deposits, with a total volume of more than 70 cubic kilometers (dense rock equivalent), were emplaced between about 300,000 years and 23,000 years B.P. (Wunderman and Rose, 1984). Wunderman and Rose (1984) inferred an Amatitlán Caldera with a resurgent dome. Postcaldera vents include a number of silicic domes in and around the caldera, and Pacaya Volcano, a basaltic and basaltic-andesite stratovolcano on the southern boundary of the caldera.
