Sea cliffs along the southern coast of Panamá west of Panama City expose pyroclastic-flow deposits from El Valle volcano.  The largest of these post-caldera explosive eruptions took place about 40,000-50,000 years ago and is named from the Río Mar, where its deposits are well exposed.  The latest plinian eruption about 34,000 years ago originated from the Mata Ahogado collapse caldera east of El Valle de Antón caldera. Photo by Lee Siebert, 1998 (Smithsonian Institution).
