This analysis details the alternating effusive and explosive activity during the Pacaya eruption, suggesting deeper volcanic processes.
Pacaya is a composite stratovolcano with a predominantly strombolian eruptive style. Located south of Lake Amatitlán and 30 kilometers south-southwest of Guatemala City. Since 1961, it has experienced periods of high and low surface activity. By the end of 2020, its activity increased significantly, marking the beginning of another highly active phase. This escalation is inferred to have been triggered by volcanic seismic events that occurred in June 2020. This paper describes the effusive eruption that took place between March 5 and April 24, 2021, during which the activity alternated between effusive activity (lava) and explosive activity (ash columns).
