Resumen

LAGOS, Marcelo. Zonificación del riesgo de tsunami en el centro-sur de Chile. Rev. geogr. Norte Gd. [online]. 2012, n.53, pp.7-21. ISSN 0718-3402.  http://dx.doi.org/10.4067/S0718-34022012000300001.

Integrating tsunami numerical modeling, geomatics techniques and new criteria developed by the tsunami risk research, develops a methodology for risk zoning and applied in a coastal area in south-central Chile. The method uses factors that influence the tsunami risk, as hydrodynamic parameters of the threat and physical and socioeconomic aspects of vulnerability. Risk factors are integrated through multicriteria evaluation techniques and Geographic Information Systems. The zoning results show that the local characteristics and their location, together with the concentration of poverty levels, establish spatial differentiated risk levels. This information builds the basis for future applied studies in land use planning, which would reduce the risk of tsunami disaster.

Palabras clave : Tsunami; tsunami modeling; risk; multicriteria evaluation.
