Abstract

The Costa Rican volacno Rincon de la Vieja is loosely but mysteriously translated as the "Old Lady's Corner." It consists of six volcanic centers that form a remote elongated ridge standing some 1300m above the surrounding terraine. Geologically speaking, the Guanacaste province of northern Costa Rica consists of a series of composite volcanic cones built on a shield of ignimbrites (welded and unwelded ash flows) of Pliocene-Pleistocene age (up to 2 million years old), that themselves lie on basement crust of Cretaceious-Tertiary age (up to 90 million years old). the active volcanoes are aligned on a northwest-southeast axis parallel to the Middle American oceanic trench in the Pacific Ocean that is the site of subduction of hte Cocos oceanic plate underneath Central America.
