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 ...
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 ...
Array analysis of the seismic wavefield of long-period events and volcanic tremor at Arenal volcano, Costa Rica
(2014-06-06)
We use wavefield decomposition methods (time domain cross correlation and frequency domain multiple-signal classification) to analyze seismic data recorded by a dense, small-aperture array located 2 km West of Arenal ...
The seismically active Andean and Central American margins: Can satellite gravity map lithospheric structures?
(2011-11-17)
The spatial resolution and quality of geopotential models (EGM2008, EIGEN-5C, ITG-GRACE03s, and GOCO-01s) have been assessed as applied to lithospheric structure of the Andean and Central American subduction zones. For the ...
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 ...
