Renewed Explosive Phreatomagmatic Activity at Poás Volcano, Costa Rica in April 2017
(Frontiers in Earth Science, 2018-10-16)Phreatic and phreatomagmatic eruptions at volcanoes often present no short termprecursory activity, making them a challenge to forecast. Poás volcano, Costa Rica, exhibits cyclic activity with phreatic and some phreatomagmatic ... -
Repeating earthquakes record fault weakening and healing in areas of megathrust postseismic slip
(American Association for the Advancement of Sciences (AAAS), 2020)Repeating earthquakes (REs) rupture the same fault patches at different times allowing temporal variations in the mechanical behavior of specific areas of the fault to be interrogated over the earthquake cycle. We study ... -

Reporte de sismos sentidos en Costa Rica entre 2010 y 2023
(Universidad Nacional, Costa Rica, 2024-01)Entre 2010 y 2023, la población costarricense ha reportado un total de 2114 sismos sentidos, lo cual representa un 1,5% del catálogo sísmico total del OVSICORI en 14 años de registro digital. Por ello, se presenta un reporte ... -
Resumen de sismicidad por meses en Costa Rica enero- diciembre 2023
(Universidad Nacional, Costa Rica, 2023)Se presenta un resumen del comportamiento sismológico en los meses de enero a diciembre del año 2023 -
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 ... -
Scattering of light by colloidal aluminosilicate particles Produces the unusual sky-blue color of Río Celeste (Tenorio Volcano Complex, Costa Rica)
(2013-09-18)Río Celeste (Sky-Blue River) in Tenorio National Park (Costa Rica), a river that derives from the confluence and mixing of two colorless streams-Río Buenavista (Buenavista River) and Quebrada Agria (Sour Creek)-is renowned ... -
Seafloor structural observations, Costa Rica accretionary prism
(1996-04-15)By studying seafloor morphology we can make associations between near surface defornation, fluid flow and the overakk structural framework of accretionary prisms. In February, 1994 a DS/RV ALVIN program to the Costa Rica ... -

(2013)Póster sobre actividad sísmica en el volcán Irazú después del terremoto del 5 de septiembre de 2012 en Nicoya, Costa Rica -
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 ... -
Seismogenic zone structure along the Middle America Trench, Nicoya Peninsula, Costa Rica, from 3D local earthquake tomography
(American Geophysical Union, 2004)Resumen de la ponencia "Estructura de la zona sismogénica a lo largo de la Fosa Mesoamericana, Nicoya Península, Costa Rica, a partir de tomografía sísmica local 3D" -

Seismogenic zone structure beneath the Nicoya Peninsula, Costa Rica, from three-dimensional local earthquake P- and S-wave tomography
(Geophysical Journal International, 2006)The subduction plate interface along the Nicoya Peninsula, Costa Rica, generates damaging large (Mw > 7.5) earthquakes. We present hypocenters and 3-D seismic velocity models (VP and VP/VS) calculated using simultaneous ... -
Seismogenic zone structure of the southern Middle America Trench, Costa Rica
(Journal of Geophysical Research, 2003-10)The shallow seismogenic portion of subduction zones generates damaging large and great earthquakes. This study provides structural constraints on the seismogenic zone of the Middle America Trench offshore central Costa ... -
Short-period volcanic gas precursors to phreatic eruptions: Insights from Poás Volcano, Costa Rica
(Elsevier, 2016-03)Volcanic eruptions involving interaction with water are amongst the most violent and unpredictable geologic phenomena on Earth. Phreatic eruptions are exceptionally difficult to forecast by traditional geophysical techniques. ... -
