Earthquake and tsunami forecasts: Relation of slow slip events to subsequent earthquake rupture
(National Academy of Sciences, 2014-11-17)
The 5 September 2012 Mw 7.6 earthquake on the Costa Rica subduction plate boundary followed a 62-y interseismic period. Highprecision GPS recorded numerous slow slip events (SSEs) in the decade leading up to the earthquake, ...
Thin-skinned mass-wasting responsible for widespread deformation at Arenal volcano
(Frontiers Media, 2014-12-03)
The shape and stability of a volcano’s edifice depends on the relationship between eruption rate and the loss or redistribution of material due to erosion, mass-wasting or deformation. This work provides measurements of ...
Camera trapping ocelots: An evaluation of felid attractants
(Universidad Nacional, Costa Rica, 2014)
Ocelots (Leopardus pardalis) and other wild cats are often surveyed using camera traps to
identify individuals for density estimation via capture-recapture analyses or estimate occupancy
via detection/non-detection ...
Comparación de la habilidad reproductiva y mortalidad del ácaro Varroa destructor en celdas con cría de obrera y zángano en abejas africanizadas de Costa Rica
(Universidad Nacional, Costa Rica, 2014-10-31)
Se estudió la reproducción del ácaro Varroa destructor en celdas con cría de obrera
y zángano. Además se evaluó la mortalidad de la progenie de V. destructor, especialmente la
muerte o ausencia del macho. El estudio se ...
Análisis de la actividad sísmica en Costa Rica durante el 2010 y resumen de los eventos sísmicos más importantes presentados en Costa Rica de 1983 - 2012
(Universidad de Costa Rica, 2014-01)
El objetivo de este trabajo es analizar la actividad sísmica registrada por la red sismográfica del OVSICORI-UNA en el año 2010; además de recopilar información de los sismos más importantes sentidos por la población del ...
Mercury fluxes from volcanic and geothermal sources: an update
(Geological Society, London, Special Publications, 2014-08-02)
We review the state of knowledge on global volcanogenic Hg emissions to the atmosphere and present new data from seven active volcanoes (Poa´s, Rinco´n de la Vieja, Turrialba, Aso, Mutnovsky, Gorely and Etna) and two ...

Poás volcano: Geophysical-Geochemical signatures and dynamics of its magmatic-hydrothermal system
(International Association of Volcanology and Chemistry of the Earth's Interior, 2014-09)
Poás volcanic complex hosts a hyper-acid lake where geochemical signatures are related to two major controlling processes: (a) The level of inux and dissolution-hydrolysis of magmatic volatiles in a sub-surface hydrothermal ...
