“…In general, the volcanic rock is composed predominantly of twopyroxene and two-pyroxene hornblende andesites, possessing plagioclases as major phenocrysts, and the Wuchishan Formation is composed of course sandstone with abundant quartz grains (Chen 1963;Wu 1967). Previous studies have shown that the acidic thermal water could react with plagioclase to neutralize the water, reduce SO 4 2-ion concentrations and generate anhydite, montmorillonite, kaolinite, calcite and alunite as hydrothermally precipitated minerals (Chen and Yang 1984;Liu et al 1984;Wang 1991;Muir and Nesbitt 1992;Nogami and Yoshida 1995;Kempter and Rowe 2000;Varekamp et al 2000;Fang et al 2003;Marini et al 2003).…”

This paper systematically surveyed distribution and field occurrences of 13 hot springs as well as geochemical investigation on the geothermal area of the Tatun Volcano Group (TVG). According to Piper diagrams, pH values, field occurrences and water-rock interactions, these hot springs can be classified into three types: (1) Type I, SO 4 2-acidic water where the reservoir is located in the Wuchishan Formation; (2) Type II, HCO 3 -a near neutral spring where waters originate from the volcanic terrane (andesite); and (3) Type III, Cl --rich acidic water where waters emanate from shallower Wuchishan Formation. In terms of isotopic ratio, δD and δ 18O values, two groups of hot spring can be recognized. One is far away from the meteoric water line of the Tatun area with values ranging between -26.2‰ and -3.5‰, and from -3.2‰ to 1.6‰, respectively. However, another close to the meteoric water line of the Tatun area is between -28.4‰ and -13.6‰, and from -5.5‰ to -4.2‰, respectively. In addition, the δ 34 S value of thermal waters can also be distinguished into two groups, one ranging from 26.1‰ to 28.5‰, and the other between 0.8‰ and 7.8‰. Based on field occurrences and geochemical characteristics, a model has been proposed to illustrate the origin of these hot springs.

“…Although water sampling did not show any link between Voui and spring water (Fig. 6), acidic water from Voui can dissolve rock during seepage leading to alteration which in turn increases the potential of masse failure, as it has been described at Rincon de la Vieja volcano (Kempter and Rowe, 2000). (2) Vegetation cover loss by gas and tephra fall, for example, SO 2 release from the summit crater between November 2005 and August 2006 have led to 15-20 km 2 vegetation damage to the north-west of Ambae, following prevailing wind directions (http://www.ulb.ac.be/sciences/cvl/aoba/Ambae1.html).…”

Abstract. Volcanic eruptions through crater lakes often generate lahars, causing loss of life and property. On Ambae volcano, recent eruptive activities have rather tended to reduce the water volume in the crater lake (Lake Voui), in turn, reducing the chances for outburst floods. Lake Voui occupies a central position in the summit caldera and is well enclosed by the caldera relief. Eruptions with significantly higher magnitude than that of 1995 and 2005 are required for an outburst. A more probable scenario for lahar events is the overflow from Lake Manaro Lakua bounded on the eastern side by the caldera wall. Morphology and bathymetry analysis have been used to identify the weakest point of the caldera rim from which water from Lake Manaro Lakua may overflow to initiate lahars. The 1916 disaster described on south-east Ambae was possibly triggered by such an outburst from Lake Manaro Lakua. Taking into account the current level of Lake Manaro Lakua well below a critical overflow point, and the apparently low potential of Lake Voui eruptions to trigger lahars, the Ambae summit lakes may not be directly responsible for numerous lahar deposits identified around the Island.

“…Faillace (1973) complementa unas notas sobre algunas fuentes termominerales en Guanacaste, dentro del marco de un proyecto de investigación de aguas subterráneas en tres áreas seleccionadas de Costa Rica. Estos estudios fueron complementados por una serie de investigaciones con fines específicamente geotérmicos, realizados por el Instituto Costarricense de Electricidad, que en primera instancia estuvieron concentrados en la cordillera de Guanacaste (Corrales, 1974(Corrales, , 1976Mainieri y Corrales, 1977;ICE, 1977;Giggenbach y Corrales, 1992;Yock, 1998;Kempter y Rowe, 2000), si bien después se extendieron a otras regiones del país con el fin de evaluar su potencial de un modo integral y su eventual explotación a corto, mediano y largo plazo. Particularmente, en 1988Particularmente, en -1989, el ICE realizó un nuevo estudio de reconocimiento del potencial para el futuro aprovechamiento de la energía geotérmica de todo el territorio nacional, tomándose muestras de la mayoría de las fuentes termales (ICE-ENEL, 1989, 1990 o realizando estudios específicos (Vargas, 2001;Rodríguez, 2002).…”

ABSTRACT:The present work present a chronological account of the discovery, research, and recreational use of the hot and mineral springs of Costa Rica. The descriptions of the investigations carried out have been divided into five periods with a first period called pre-Columbian stage, conquest and Colony until 1755. The second period is defined from 1755 to1854, where the first formal descriptions are presented. The third period includes the first scientific investigations made by European scientists (1855 -1873). The fourth period refers to a reduction in the number of researches (1874 -1954) and the fifth, and last period includes modern research for recreational purposes and applied engineering (1955 -present). The main use of the geothermal energy is for electricity generation, and the mineral and hot springs has been use for tourism, in particular areas associated with volcanic terrains and faults; however, for therapeutic and medicinal use it is still very limited. Keywords: Hot spring, mineral springs, history, discovery, exploitation, use, Costa Rica. RESUMEN:Se presenta un recuento cronológico del descubrimiento, de las investigaciones, y del aprovechamiento con fines recreativos de las fuentes termales de Costa Rica. La descripción de las investigaciones realizadas se ha dividido en cinco períodos con un primer período denominado etapa precolombina, conquista y colonia hasta 1755. El segundo período considerado desde 1755 hasta 1854 donde se presentan las primeras descripciones formales. El tercer período considerando que incluye las primeras investigaciones científicas a cargo de científicos europeos (1855 a 1873). El cuarto período se refiere a una reducción en el ímpetu de las investigaciones (1874 hasta 1954) y el quinto período que incluye las investigaciones modernas con fines comerciales y aplicados a la ingeniería (1955 -presente). El principal aprovechamiento ha sido la extracción de la energía geotérmica para la generación de energía eléctrica, y el uso de las fuentes termales con fines turísticos en zonas particulares asociadas con aparatos volcánicos; sin embargo, para el uso terapéutico y medicinal es aún muy limitado.
