Resumen
Los mareógrafos de Puntarenas, Quepos y Limón fueron instalados en la década de 1940 como una colaboración entre el Instituto Geográfico Nacional (IGN) y la Agencia Nacional Atmosférica y Oceanográfica de los Estados Unidos (NOAA). El IGN enviaba los rollos de papel con los regis- tros mareográficos a la NOAA, quienes los procesaban y los devolvían al IGN para su almacenamiento. Sin embargo, en 1969 estos rollos de papel fueron destruidos en el IGN. Recientemente, gracias a la colaboración del Centro Nacional de Información Ambiental (NCEI) de la NOAA, hemos recuperado varios registros de tsunamis anteriores a ese año, correspon- dientes al mareógrafo de Puntarenas, en forma de imágenes digitales.
Los registros incluyen tres tsunamis locales y tres lejanos. Los eventos locales corresponden a dos tsunamis en 1941 en la Península de Osa (Mw 7.3 y Mw 6.9), y uno en 1950 en la Península de Nicoya (Mw 7.8). Los eventos lejanos corresponden a los tsunamis de Kamchatka, Rusia, de 1952 (Mw 9.0), Islas Andreanof, Alaska de 1957 (Mw 8.7) y Chile de 1960 (Mw 9.5). Estos mareogramas de tsunamis no han sido publicados anteriormente, aunque sí constan en bases de datos de tsunamis con las alturas máximas.
The Puntarenas, Quepos and Limón tide gauges were installed in the 1940s as a collaboration between the National Geographic Institute (IGN) and the United States National Atmospheric and Oceanographic Agency (NOAA). IGN sent the rolls of paper with the tide gauges to NOAA, who processed them and returned them to IGN for storage. However, in 1969 these rolls of paper were destroyed at the IGN. Recently, thanks to the collaboration of NOAA's National Center for Environmental Information (NCEI), we have recovered several records of tsunamis prior to that year, corresponding to the Puntarenas tide gauge, in the form of digital images. The records include three local and three distant tsunamis. The local events correspond to two tsunamis in 1941 in the Osa Peninsula (Mw 7.3 and Mw 6.9), and one in 1950 in the Nicoya Peninsula (Mw 7.8). The distant events correspond to the tsunamis of Kamchatka, Russia, of 1952 (Mw 9.0), Andreanof Islands, Alaska of 1957 (Mw 8.7) and Chile of 1960 (Mw 9.5). These tsunami gauges have not been published before, although they do appear in tsunami databases with the maximum heights.
