From: Response of a hydrothermal system to escalating phreatic unrest: the case of Turrialba and Irazú in Costa Rica (2007–2012)

Fig. 1

Inset: simplified map of Costa Rica with the location of Irazú and Turrialba volcanoes at the SE termination of Cordillera Central volcanic ridge. White triangles are volcanoes. The inset is a sketch of Central America geodynamics dominated by the Cocos-Caribbean subduction. a Morpho-structural sketch map of Irazú and Turrialba volcanoes, showing the main volcanic and tectonic features in the study area. The Hillside or ShadowRelieve image was elaborated by Y. Alpízar on the basis of the topographic maps 1:50,000 scale from the National Geographic Institute of Costa Rica. Symbols as in Fig. 2b. Numbered points in the figures indicate meters above sea level. b Sampling points of main fumaroles (FUM Irazù fumaroles, AQ Arbol Quemado fracture) and crater lakes (IL Irazú lake, TL Turrialba lake) in the summit of Irazú and Turrialba volcanoes, together with location of the studied thermal springs (SC San Cayetano, ST Santa Teresita, OJA Ojo de Agua, BLP Bajo Las Peñas, HBA Hervideros de Buenos Aires) and water sampling points from the rivers along the volcano flanks (white triangles). Labels of sampling points conform to the following diagrams and tables
