To quantify this process and identify coastal erosion hotspots in the Caribbean south, a methodology was proposed for detecting and delineating the shoreline using aerial photographs and high-resolution satellite imagery to determine the rate of coastline retreat, the employed photographs and images cover the period between 2005 and 2016. By such means it was possible to identify eleven erosion hotspots, as well as estimation of their retreat rates for the periods 2005-2010 and 20102016. The localities that have experienced the greatest erosion of their sandy beaches are Cahuita National Park, Westfalia and Bananito Beach. Desde el 2010 en la prensa local se ha venido reportando un proceso acelerado de erosión en playas arenosas del litoral caribeño costarricense, que incluso ha sido documentado al interior de las áreas protegidas. Para cuantificar este proceso e identificar los puntos calientes por erosión costera en el Caribe Sur, se planteó una metodología que consiste en levantar la línea de costa a partir de fotografías áreas e imágenes satelitales de alta resolución espacial, con el fin de determinar la tasa de retroceso de la costa. Las fotos e imágenes utilizadas cubren un periodo entre 2005 y 2016. De esta forma fue posible identificar once puntos calientes de erosión, así como la estimación de sus tasas areales de retroceso para dos periodos (2005-2010 y 2010-2016). En este sentido, las localidades que han experimentado la mayor erosión en sus playas arenosas son el Parque Nacional Cahuita, Westfalia y playa Bananito.
