Mexico, and most of the volcanoes therein are located predominately within the Guerrero Block and includes the Paleogene and Neogene/Quarternary arcs. Guatemala, Honduras and Nicaragua are both located within the Chortis Block whereas the Nicoya Complex flanks Costa Rica on the east by the Limon Basin and on the west. Panama is also part of the Nicoya Basin, flanked on the west and on the east, flanked by the North Panama Fold Belt.
