Seismic Source of the Chile 2010 Earthquake from Inversion of Geodetic Data and Observations
Descripción del Articulo
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 coseis...

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 side of the rupture area. The calculated "geodetic"scalar moment is 1.25 × 1022 Nm, which is equivalent to a magnitude of 8.7 Mw.El 27 de febrero de 2010 un terremoto de magnitud 8.8 Mw (según el USGS) sacudió la región centro-sur de Chile con un saldo de más de 500 muertos. Como efecto cosísmico se originó un maremoto que destruyó muchos poblados y balnearios costeros, así como la deformación permanente de la corteza. Esta deformación cosísmica puede ser cuantificada mediante mediciones geodésicas: GPS, observaciones de campo en el litoral y datos de interferometría satelital InSAR. Del análisis y procesamiento de los datos geodésicos se puede obtener los parámetros que caraterizan la distribución de la fuente sísmica mediante un proceso de inversión, en el cual se compara la data simulada con la data observada a través de un proceso de inversión con el método de mínimos cuadrados no-negativos. Los resultados muestran la existencia de dos asperezas principales situados al norte y al sur del epicentro. El valor máximo de la dislocación es 17.3 m ubicado en la parte norte del área de ruptura. El momento "geodésico" escalar calculado es 1.25 × 1022 Nm, que equivale a una magnitud de 8.7 Mw.Universidad Nacional Mayor de San Marcos2018-01-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/fisica/article/view/1516610.15381/rif.v20i2.15166Revista de Investigación de Física; Vol. 20 No. 2 (2017); 9-14Revista de Investigación de Física; Vol. 20 Núm. 2 (2017); 9-141728-29771605-7724reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/fisica/article/view/15166/13156Derechos de autor 2018 César Jiménez, Miguel Saavedra, Nabilt Moggiano, Nick Morenohttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/151662021-08-17T19:55:15Z |
