ANTOLOGÍA SOBRE POLITIONATOS: COMPUESTOS DE AZUFRE EXISTENTES EN LOS LAGOS CRATÉRICOS DE VOLCANES ACTIVOS
(Revista de Vulcanología, Sismología y Tectónica., 1999)En la siguiente recopilación bibliográfica sobre los oxianiones de azufre llamados politionatos, con fórmula general SxO6 2-, se contemplan algunas de sus propiedades físico-químicas, y se hace énfasis principalmente en ... -
Are the ashes from the latest eruptions (2010–2016) at Turrialba volcano (Costa Rica) related to phreatic or phreatomagmatic events?
(Elsevier, 2016-09-15)The initial eruptive episodes of explosive eruptions are classified as phreatic if the amount of juvenile material (scoria, glass, pumice) is null, and the amount of fresh accidental lithics, and hydrothermally altered ... -
Arsenic in wells at the Guayabo Caldera in Northwest Costa Rica
(International Association of Volcanology and Chemistry of the Earth's Interior, 2018-09)The Guayabo Caldera, a 14 km diameter volcanic depression with Miravalles volcano rising 2028 ma.s.l. in the norte astern side of so called, formed by repeated eruption sand multiple collapses which dis membered earlier ... -
Aspectos espeleogenéticos, hidrogeológicos y de geomorfología kárstica de Venado de San Carlos
(Universidad de Costa Rica, 2019)En los últimos años, personal de la UCR con colaboración de espeleólogos y la administración de Cavernas de Venado, realizó la cartografía de aproximadamente 5 kilómetros de pasajes de cuevas. Esta cartografía ha permitido ... -

Caracterización de Quebrada Paredes. Aspectos geomorfológicos y relación con zona de afectación volcánica: Volcán Turrialba
(Universidad Nacional, Costa Rica, 2016)Se realizó una visita a la cuenca de Quebrada Paredes el 14 de enero de 2016 con varios propósitos. Este informe detalla aspectos físicos del cauce y sus alrededores, así como descarta elementos considerados en el pasado ... -
Carbon and sulfur isotopes in tree rings as a proxy for volcanic degassing
(Geological Society of America, 2019-07-05)Trees are useful archives of past atmospheric conditions. They have most commonly been used to infer large-scale changes in climate, industrial pollution, and the magnitude and frequency of geological hazards. While ... -
Carbon isotope systematics of Turrialba volcano, Costa Rica, using a portable cavity ring-down spectrometer
(AGU Publications, 2017-07-27)Over the past two decades, activity at Turrialba volcano, Costa Rica, has shifted from hydrothermal to increasingly magmatic in character, with enhanced degassing and eruption potential. We have conducted a survey of the ... -
Chlorine isotope and Cl–Br fractionation in fluids of Poás volcano (Costa Rica): Insight into an active volcanic–hydrothermal system
(Elsevier, 2016-10-01)Halogen-rich volcanic fluids issued at the surface carry information on properties and processes operating in shallow hydrothermal systems. This paper reports a long-term record of Cl–Br concentrations and δ37Cl signatures ... -
Chlorine isotope variations in the hyper-acid lake system of Poás volcano, Costa Rica
(International Association of Volcanology and Chemistry of the Earth's Interior, 2013-07)This study provides some datasets of the most salient geochemical signatures of the acid lake and their strongly uctuating behaviour observed over the last 30 years. -

Co-ideation of disaster preparedness strategies through a participatory design approach: Challenges and opportunities experienced at Turrialba volcano, Costa Rica
(Elsevier, 2015)Disaster preparedness is key to coping and adaptation during the immediate aftermath of a natural hazard, but the majority of those at risk do not feel prepared. In this participatory action research we investigate the ... -
Coastal Deformation Patterns Along the Nicoya Seismic Gap, Pacific Coast, Costa Rica, Central America

Coda wave attenuation in Mara Rosa seismic zone
(Sociedade Brasileira de Geofísica, 2013-08-26)Small local earthquakes from aftershock sequence in Mara Rosa, Goiás state, Brazil were used to estimate the coda wave attenuation in the frequency band of 1 to 20 Hz. The time-domain coda-decay method of a single ... -
Coda wave attenuation in the Parecis Basin, Amazon Craton, Brazil: sensitivity to basement depth
(Springer, 2011)Small local earthquakes from two aftershock sequences in Porto dos Gaúchos, Amazon craton—Brazil, were used to estimate the coda wave attenuation in the frequency band of 1 to 24 Hz. The time-domain coda-decay method of ... -
Combined GPS, EDM and triangulation surveys of the rapid downslope motion of the western flank of Arenal Volcano, Costa Rica
