Los riesgos y desastres naturales en la cotidianidad de los barrios de Lepanto, Puntarenas, Costa Rica
(Universidad Nacional, Costa Rica., 2018)
El presente artículo nace en el marco del proyecto “Educación para la prevención de riesgos naturales” utilizado como parte del proceso de extensión y docencia de Instituto de Investigación Observatorio Vulcanológico y ...
Seismic cycle and plate margin deformation in Costa Rica: GPS observations from 1994 to 1997
(American Geophysical Union, 1999-12-10)
Global Positioning System (GPS) observations in Costa Rica from 1994 to 1997 reveal a complex pattern of motion consistent with the superposition of seismic cycle and secular
plate margin deformation. In the south, velocity ...
Analysis of seismic and acoustic observations at Arenal Volcano, Costa Rica, 1995–1997
(Elsevier Science, 2000-08)
In November 1995, we installed five, three-component broadband seismometers and electronic tiltmeters around the circumference of Arenal Volcano, a young stratovolcano in Costa Rica that exhibits strombolian activity. With ...
La actividad explosiva del volcán Turrialba (Costa Rica) en el período 2010 - 2016
(Universidad de Costa Rica, 2016-12-18)
The most recent eruptive activity of Turrialba volcano began on the 5th of January 2010, after more than a century of dormancy. The fragmentation process and aerodynamic behavior of the ash from Turrialba’s vulcanian ...
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 ...
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 ...
Hypoglycemic and antihyperglycemic effect of Witheringia solanacea in normal and alloxan-induced hyperglycemic rats
(Elsevier, 2011)
Witheringia solanacea is a small shrub that belongs to the Solanaceae family. The plant is used as an antidiabetic in Costa Rican herbal medicine. The aim of this study was to evaluate the hypoglycemic and antihyperglycemic ...
Informality, social citizenship, and wellbeing among migrant workers in Costa Rica in the context of COVID-19
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-20)
Costa Rica is home to 557,000 migrants, whose disproportionate exposure to precarious, dangerous, and informal work has resulted in persistent inequities in health and wellbeing in the midst of the COVID-19 pandemic. We ...
Nest-specific composition of the trail pheromone of the stingless bee Trigona corvina within populations
(Springer, 2012)
Social insects have evolved highly developed communication systems, enabling them to coordinate complex interactions in their colonies. Pheromones play a major role in the coordination of many tasks. In Trigona corvina, a ...
Learnt information in species-specific ‘trail pheromone’ communication in stingless bees
(Elsevier, 2013)
Specificity in biological signalling systems is often important to keep information private. Foragers of
several species of stingless bees deposit chemical marking signals to guide nestmates to food sources.
The markings ...
