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 ...
Regional characteristics of observable foreshocks
(Seismological Society of America (SSA), 2022)
Measures of foreshock occurrence are systematically examined using earthquake catalogs for eight regions (Italy, southern California, northern California, Costa Rica, Onshore Japan, Alaska, Turkey, and Greece) after imposing ...
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 ...
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 ...
