Propone desarrollar una metodología para obtener la distribución de la fuente sísmica para sismos tsunamigénicos a partir de la inversión de formas de onda de tsunami y datos geodésicos. Se plantea las aplicaciones a eventos sísmicos y tsunamis que han afectado el litoral costero peruano. Por ejemplo, el sismo y tsunami de Lima de 1940 (8.0 Mw), el sismo y tsunami de Huacho de 1966 (8.1 Mw), a partir de la inversión de 3 registros mareográficos. El sismo y maremoto de Camaná de 2001 (8.4 Mw) a partir de la inversión combinada de datos mareográficos y geodésicos. El sismo y maremoto de Pisco 2007 (8.0 Mw), a partir de la inversión de datos mareográficos. El sismo y maremoto de Chile 2014 (8.1 Mw) a partir de la inversión combinada de datos mareográficos y geodésicos. Se enfatiza la aplicación de la prueba de confiabilidad para evaluar la resolución y el rango de aplica...

On 23 June 2001, at 15:33 local time, the Camana city and all the Peruvian southern region were hit by a strong earthquake of magnitude 8.4 Mw and maximal intensity VIII in Mercalli scale. The epicenter was located on the sea in the forefront of Ocoña (Arequipa). Fifteen minutes later, a localized tsunami was generated, which destroyed the seaside town of Camana and caused the death of 24 people an 62 missing people. This event is the objet study through numerical simulations implementing the TIME model for tsunamis, the results obtained are the arrival time, the run up (maximal height of flooding), synthetic tidal gage recording and flooding maps, which will

On October 17, 1966 at 21:41 UTC, a big earthquake shooked the central region of Peru, causing 100 deaths. The maximum severity of shaking was reported in the Huacho city (VIII-IX MM). As coseismic effect a tsunami was generated, which flooded some villages and beach resorts, as Casma and Tortugas. From analysis and signal processing of three tidal records observed at stations of Chimbote, Callao and Marcona, we determined the parameters of the seismic source through an inversion process, in which the computed signal is compared with the observed signal by a non-negative least square process. The maximum slip is 4.7 m and is located in the Southern side of rupture geometry, which means that the maximum asperity or zone of greatest energy release is located under the Ocean in front of the Huacho city, this is consistent with the maximum intensity values reported. The scalar tsunami mome...

The earthquake and tsunami of 1868, on the coast of the South Pacific caused the disappearance of the city of Arica in Peruvian territory. Faced with this situation, the government of President José Balta decrees a policy plan for the reconstruction and reactivation of the city due to its geopolitical importance for the traffic of goods from southern Peru and Bolivia. The project is entrusted to the French office Eiffel et Cie, which traces an industrial project, the proposal for a modern regular layout burst with the dense irregular layout of the pre-existing city, this also included the new steam mobility systems of the Railway era and Port. A historical reconstructive method is applied, some results of the tools are exposed: mapping, interviews, photographic observation sheets, planimetric and aero-photogrammetric surveys. As a result, a spatial theoretical interpretation is obtained...

On February 27, 2010 an earthquake of magnitude 8.8 Mw (according to USGS) shook the center-southern region of Chile with a balance of more than 500 deaths. As a coseismic effect, a tsunami was generated which destroyed many coastal villages, as well as the permanent crustal deformation. This coseismic deformation can be quantified by geodetic measurements: GPS, field observations at the littoral and InSAR satellite interferometry data. From the analysis and processing of the geodetic data it is possible to obtain the parameters that characterize the distribution of the seismic source through an inversion process, in which the simulated data is compared with the observed data using the non-negative least squares method. The results show the existence of two main asperities located to the north and south of the epicenter. The maximum slip or dislocation was 17.3 m located in the northern ...
