Evaluación de mezclas de fungicidas alternativos para el control de sigatoka negra [Pseudocercospora fijiensis (M. Morelet) Deighton] en el cultivo de banano (Musa spp.) en Costa Rica
(Universidad Nacional (Costa Rica), 2023-05)El objetivo de este estudio fue evaluar el comportamiento y desempeño de mezclas de fungicidas con coadyuvantes, con la finalidad de generar nuevas estrategias alternativas para el control de sigatoka negra (Pseudocercospora ... -
OKSP: a novel deep learning automatic event detection pipeline for seismic monitoring in Costa Rica
(Instituto de Ingenieros Eléctricos y Electrónicos (IEEE), 2021)Small magnitude earthquakes are the most abundant but the most difficult to locate robustly and well due to their low amplitudes and high frequencies usually obscured by heterogeneous noise sources. They highlight crucial ... -
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 ... -
The 27 February 2022 Lop Nor earthquake: detectability, location, and discrimination
(Seismological Society of America (SSA), 2022)A seismic event with mb 4.8 (Mw 4.2) was detected close to the Chinese Lop Nor nuclear test site on 27 February 2022. Waveforms recorded at regional and far regional distances in central Asia indicate greater likeness with ... -
Yield estimate (230 kt) for a Mueller-Murphy model of the 3 september 2017, North Korean nuclear test (mbNEIC = 6.3) from teleseismic broadband P waves assuming extensive near-source damage
(AGU Advancing Earth and Space Sciences, 2018)The 3 September 2017 underground nuclear test (mbNEIC= 6.3) is the largest of six announced North Korean explosions. The event generated many P wave seismograms at global broadband seismic stations with good signal-to-noise ... -
Yield estimates for the six North Korean nuclear tests from teleseismic P wave modeling and intercorrelation of P and Pn recordings
(AGU Advancing Earth and Space Sciences, 2019)The yields of the six declared underground nuclear tests at the North Korean test site are estimated using high-frequency teleseismic P wave amplitude modeling and waveform equalization of short-period teleseismic P waves ...
