Historical Tsunamis at the Costa Rican Caribbean Coast
(Universidad de Costa Rica, 2021-04-22)
Aún cuando los tsunamis son poco frecuentes en el Caribe de Costa Rica, pueden llegar a ser destructivos. En Costa Rica existe la creencia errónea de que no hemos tenido tsunamis. Sin embargo, los autores encontraron ...
La depresión tectónica de Nicaragua en Costa Rica: estructura interna, estilo estructural, edad, extensión y actividad de la cuenca de San Carlos
(Universidad de Costa Rica, 2021-05-05)
Nicaragua’s tectonic depression extends from El Salvador to the plains in northern Costa Rica and is limited by strike-slip faults with a normal component. Based on a set of unpublished seismic lines, ...
First record of Scapholeberis freyi Dumont and Pen- saert, 1983 (Crustacea:Anomopoda: Daphniidae) from Colombia
(Universidad Nacional Mayor de San Marcos, Perú., 2021)
From the analysis of plankton samples from a temporary pond of northern Colombia
some female specimen of the daphinid cladoceran Scapholeberis freyi Dumont and

Biocomposites of Low-Density Polyethylene PlusWood Flour or Flax Straw: Biodegradation Kinetics across Three Environments
(MDPI journals, 2021-06-29)
The purpose of this study was to assess the potential for biocomposite films to biodegrade in diverse climatic environments. Biocomposite films based on polyethylene and 30 wt.% of two lignocellulosic fillers (wood flour ...
Evaluación del potencial de tsunamis locales con base en análisis sismo-tectónico en el Caribe de Costa Rica
(Universidad de Costa Rica, 2021-04-22)
En Costa Rica, pese a su relativa baja frecuencia, los tsunamis suponen un riesgo en las comunidades costeras. La integración de información geofísica y geológica permite la interpretación de posibles áreas de ruptura para ...
A first estimation of tsunami hazard of the Pacific coast of Costa Rica from local and distant seismogenic sources
(Springer, 2021-06-04)
Costa Rica has been affected by several local and distant tsunamis in the past, but the historical information is scarce and incomplete. Its Pacific coast stretches for over a thousand kilometers, and tsunami hazard has ...
