Deep neural networks for earthquake detection and source region estimation in north-central Venezuela
Tous Liesa, Rubén; Alvarado Bermúdez, Leonardo; Otero Calviño, Beatriz; Cruz de la Cruz, Stalin Leonel; Rojas Ulacio, Otilio (2020-10-01)
Article
Open AccessReliable earthquake detection algorithms are necessary to properly analyze and catalog the continuously growing seismic records. We report the results of applying a deep convolutional neural network, called UPC‐UCV ... -
Electromagnetic subsurface imaging in the presence of metallic structures: a review of numerical strategies
Castillo Reyes, Octavio; Queralt Capdevila, Pilar; Piñas Varas, Perla; Ledo Fernández, Juanjo; Rojas Ulacio, Otilio (2024-08-28)
Article
Open AccessElectromagnetic (EM) imaging aims to produce large-scale, high-resolution soil conductivity maps that provide essential information for Earth subsurface exploration. To rigorously generate EM subsurface models, one must ... -
Random forest parameterization for earthquake catalog generation
Llácer Giner, David; Otero Calviño, Beatriz; Tous Liesa, Rubén; Monterrubio Velasco, Marisol; Carrasco Jiménez, José; Rojas Ulacio, Otilio (Springer, 2020)
Conference report
Open AccessAn earthquake is the vibration pattern of the Earth’s crust induced by the sliding of geological faults. They are usually recorded for later studies. However, strong earthquakes are rare, small-magnitude events may pass ... -
Small-layered feed-forward and convolutional neural networks for efficient P wave earthquake detection
Mus León, Sergi; Otero Calviño, Beatriz; Alvarado Vivas, Leonardo; Canal Corretger, Ramon; Rojas Ulacio, Otilio (2022-11-15)
Article
Open AccessThe number and efficiency of seismic networks have steadily increase over time delivering large datasets to be analyzed for earthquake occurrence. Automatic tools for accurate earthquake detection are under emerging and ...
