Spatial variability of the b-value and seismic potential in Costa Rica
(2021-06)
Costa Rica is a seismically active region located in a subduction zone. Combining earthquake data from the National Seismological Network and several Central American catalogs from 1522 to 2020, we present a new estimation ...
El Sistema de Falla Navarro: desplazamientos izquierdos a lo largo del Cinturón Deformado del Centro de Costa Rica
The Navarro fault system: Left-lateral displacements along the central Costa Rica deformed belt
(2016)
En este estudio se define el sistema de falla Navarro con base en observaciones geológicas, geomorfológicas y sismológicas. Este sistema de falla está localizado entre las estribaciones norte de la cordillera de Talamanca ...
Lithospheric structure of Pampean Flat Slab (latitude 30-33°s) and Northern Costa Rica (latitude 9-11°n) Subduction Zones
(2011)
The Pampean flat slab subduction in west-central Argentina (latitude 30-33S) and the steeply dipping Northern Costa Rica subduction zone (latitude 9-11N) show significant along-trench variations in both the subducting and ...
The National Seismological Network of Costa Rica (RSN): An Overview and Recent Developments
(2018-03)
The National Seismological Network of Costa Rica (RSN) is a joint effort between the University of Costa Rica (UCR) and the Costa Rican Institute of Electricity (ICE). In this article, we briefly describe its history, ...
Evidence for Caribbean plate subduction in southern Costa Rica
(2023)
Nestled between the Cocos, Nazca, Caribbean, and South American plates, the Panama
microplate represents an area of rapidly evolving tectonics throughout the past ∼10 m.y. Past
and current studies have observed a notable ...
Geometría de la zona sismogénica en el sureste de Costa Rica con base en la secuencia sísmica de Golfito del 2018
(2021-01-01)
Entre agosto y noviembre del 2018 ocurrió una secuencia de sismos en el golfo Dulce, cerca de la ciudad de Golfito, al sureste de Costa Rica. El sismo principal tuvo una magnitud momento (Mw) 6.1 y fue sentido en Costa ...
Distribución geográfica de los sismos contenidos en el catálogo de la Red Sismológica Nacional de Costa Rica
Geographic distribution of the earthquakes included in the catalog of National Seismological Network of Costa Rica
(2018)
En este artículo se analiza la distribución espacio-temporal de la sismicidad en Costa Rica, contenida
en el catálogo sísmico de la Red Sismológica Nacional para el periodo 1975-2014. La distribución
geográfica de la ...
Analysis of Seismic Activity near Theodore Roosevelt Dam, Arizona, during the Occupation of the EarthScope/USArray Transportable Array
(2012)
Rate and distribution of seismic activity are important indicators of the overall state of tectonic stress within a region. In regions characterized by low levels of seismicity, active fault surfaces are rarely visible at ...
COVID-19 lockdown effects on the seismic recordings in Central America
(2021-09-30)
A noticeable decrease in seismic noise was registered
worldwide during the lockdown measures implemented
in 2020 to prevent the spread of COVID-19. In Central America,
strong lockdown measures started during March of ...
Nature of crustal terranes and the Moho in northern Costa Rica from receiver function analysis
(2010-01)
The Central American subduction zone in northern Costa Rica shows along‐strike variations in both the incoming and overriding plates. By analyzing the subducting oceanic Moho (M1) and the upper plate Moho (M2) with receiver ...
