Geological aspects of paleoseismicity and archaeosismology in the fluvial alluvial Rimac valley / Aspectos geológicos de paleosismicidad y arqueosismología en el valle fluvio-aluvial del Rímac

Jacay, Javier 10 April 2018 (has links)
The sedimentary fill of the Rimac River fluvial-alluvial plain (Upper Miocene-Quaternary) consists of a thick sequence of unconsolidated material that corresponds to fluvial deposits. A record of seismotectonic activity is presentedin the sedimentary levels of fine facie within numerous paleoseismic structures such as contoured layers, pseudonodules, load figures, and material injections. Additionally, wall inclination and collapse, as well as displacement and partialfracturing, and pavement deformation, etc. are observed in the pre-Hispanic buildings located on the fluvial-alluvial plain. These sedimentological and architectural observations illustrate the periodicity of seismic events in the largefluvial-alluvial plain of the Rimac River. / El relleno sedimentario de la llanura fluvio-aluvial del río Rímac (Mioceno Superior-Cuaternario) está compuesto por una gruesa secuencia de material inconsolidado que corresponde a depósitos de origen fluvial. Es en los niveles sedimentarios de facies finas, donde la actividad sismotectónica está presente mediante manifestaciones de numerosas estructuras de paleosismicidad, como capas contorneadas, pseudonódulos, figuras de carga e inyecciones de material. Asimismo, en las edificaciones prehispánicas localizadas sobre esta llanura fluvio-aluvial se observa inclinaciones y colapso de paredes, desplazamiento de bloques de los muros, fractura parcial de los muros, deformación de pavimentos, etc. Son estas observaciones sedimentológicas y arquitectónicas las que nos manifiestan la periodicidad de eventos sísmicos en la gran llanura fluvio-aluvial del Rímac.
