RESUMEN: Uno de los sismos de mayor magnitud que ha sufrido Chile ocurrió la madrugada del 27 de febrero de 2010. Provocó una ruptura de aproximadamente 450 km de extensión, justo frente a la costa de la península de Arauco a Valparaíso. El hipocentro se ubicó frente a una pequeña población típica llamada Cobquecura, muy cercana a la costa, a unos 400 km al sur de Santiago, y a unos 100 km al norte de Concepción. Se exponen en este artículo las observaciones realizadas en esa zona por un grupo de reconocimiento del Instituto de Ingeniería de la UNAM; en este caso, expresamente de los aspectos geotécnicos que pudieron distinguirse dentro de los factores que provocaron la ocurrencia de daños en Concepción, la segunda ciudad más grande de Chile, y sus alrededores. Se exponen aspectos relativos al tsunami y a efectos de sitio y a fenómenos de licuación y desplazamiento lateral; así mismo, se discuten casos específicos del comportamiento de cimentaciones, puentes, silos, terraplenes, y otras estructuras.
