[ESP] Se presentan los resultados de la evaluación geológico-geodinámica y el análisis de susceptibilidad por movimientos en masa que constituyen riesgos potenciales para Lima Metropolitana y el Callao. Ello involucra la caracterización y el inventario de procesos de geodinámica superficial, realizados por el INGEMMET entre los años 1970 y 2011, los que han permitido identificar las zonas críticas vulnerables a estos fenómenos. En el área de estudio, se han registrado un total de 848 peligros geológicos recientes y antiguos. Para ello, se recurrió a fuentes bibliográficas técnicas, herramientas de teledetección (fotografías aéreas e imágenes de satélite), así como del trabajo de campo para cartografiar y georreferenciar los procesos y representarlos en mapas temáticos mediante el uso de sistemas de información geográfica (SIG). Para prevenir los posibles desastres por movimientos en masa en Lima Metropolitana y el Callao, es necesario evaluar al detalle las zonas críticas de muy alta susceptibilidad. En tal sentido, el mapa de susceptibilidad representa una herramienta clave en la toma de decisiones y contribuye considerablemente a la gestión del riesgo geológico de las regiones involucradas.
[ENG] The results of the geological and geodynamic assessment are presented. Besides analysis of landslide susceptibility is made which are of high potential risks to Metropolitan Lima and Callao. This involves the characterization and inventory of surface geodynamic processes, performed by the Geological Institute of Peru (INGEMMET) between 1970 and 2011, which have lead us to identify the critical areas vulnerable to these surface geodynamic processes. In the study area, there have been a total of 848 recent and ancient geological hazards. To do this, we haveused technical literature sources, tools of remote sensing (aerial photographs and satellite images). A fieldwork was done as well, for mapping and geo-referencing processes and represent them in thematic maps using Geographic Information Systems (GIS). To prevent potential landslide disasters in Lima and Callao Metropolitan is necessary to evaluate in detail the critical areas of high susceptibility. In this regard, the susceptibility map is a key tool in the decision making process and significantly contributes to the management of geological risk regions involved.
