Resumen
Durante el año 2022, la Red Sismológica Nacional (RSN) localizó 4763 sismos locales, lo cual equivale a la energía
sísmica liberada por un terremoto de magnitud momento (Mw) 7,0. Los epicentros se concentraron principalmente en nueve zonas
con 25-400 temblores. Se documentaron 184 sismos (~4 % del total) sentidos por la población, incluyendo 19 con Mw entre 5,0 y
6,7. La mayoría de estos eventos fueron superficiales (~87 % < 30 km), de magnitud baja (~52 % Mw < 3,9) y fueron originados
en fallas de las placas Caribe y Panamá (~52 %). El sismo de mayor tamaño del año, de Mw 6,7, se originó por la subducción de la
placa Nazca y generó la intensidad más alta reportada, de V en Burica. Todos los sismos de Mw ≥ 5,5 tuvieron sus epicentros mar
adentro y alejados de centros poblados, por lo que no se reportaron intensidades altas.
During 2022, the National Seismological Network (RSN) located 4763 local earthquakes, which is equivalent to the seismic energy released by an earthquake of moment magnitude (Mw) 7.0. The epicenters were mainly concentrated in nine areas with 25-400 events. A total of 184 earthquakes (~4 % of the total) were felt by the population, including 19 with Mw between 5.0 and 6.7. Most of these events were shallow (~87 % < 30 km), of low magnitude (~52 % Mw < 3.9), and originated by faults in the Caribbean and Panama plates (~52 %). The largest earthquake of the year, Mw 6.7, was related to the subduction of the Nazca plate and generated the highest reported intensity of V in Burica. High intensities were not reported because all of the Mw ≥ 5.5 earthquakes were located offshore and far from populated centers.
