Consideration of the seismic hazard on the land use planning of the Poas Canton, Costa Rica

To incorporate the seismic hazard assessment in the land use planning can be done using seismic methods and Geographic Information System (GIS), in order to avoid the use of simplifications provided in law. In this paper, we used the deterministic method for assessment of the seismic hazard in Poas...

In this paper, we used the deterministic method for assessment of the seismic hazard in Poas County, Province of Alajuela, Costa Rica. Following this method, we identified the seismic sources that represent the main threat to the county, and the possible maximum magnitudes; the seismic attenuation, as well as the maximum acceleration values that were transformed into seismic intensity. The use of a GIS allowed the estimate of values in a 5x5 m mesh, in order to generate the seismic hazard maps at appropriate scale for the land use planning.

La valoración de la amenaza sísmica para su incorporación en el Ordenamiento Territorial puede ser realizada por medio de la combinación de los métodos propios de la sismología y del uso de Sistemas de Información Geográfica (SIG), evitando el uso de simplificaciones que son impulsadas en la normativa costarricense. En esta investigación se ejemplifica la aplicación del método determinístico en la evaluación de la amenaza símica del cantón de Poás, provincia de Alajuela, Costa Rica. A partir de este enfoque se identificaron las fuentes sísmicas que representan la mayor amenaza para el cantón y sus magnitudes máximas posibles, la atenuación sísmica, así como los valores de aceleración (PGA) esperados que son trasformados en intensidades (IMM); con base en lo cual se eligió el peor escenario posible. El uso de un SIG facilitó la implementación de las fórmulas a nivel de píxeles de 5x5 m, lo que hizo posible la elaboración de cartografía de amenaza a una escala apropiada para su implementación en el Ordenamiento Territorial. Los resultados obtenidos muestran que la parte norte del cantón presenta la mayor amenaza (IMM IX), y que la ciudad principal, San Pedro, puede verse afectada por una intensidad máxima de IX en el peor escenario Universidad Nacional,Costa Rica Departamento de Geografía, Universidad del Valle Escuela de Ciencias Geográficas 2021-03-25T14:47:46Z 2021-03-25T14:47:46Z 2016-07-03 http://purl.org/coar/resource_type/c_6501 http://hdl.handle.net/11056/18939 eng Acceso abierto https://creativecommons.org/licenses/by/4.0/ application/pdf Boletin de Geologia
