The Mexico Earthquake of September 19, 1985—New Accelerograph Network for Mexico City
As a result of the observed effects induced by the earthquakes of September 1985 in Mexico City's structures, the local government authorities increased their support for the installation of accelerographs in a network covering different zones of Mexico City. This paper presents the activities developed by the Centro de Instrumentación y Registro Sísmico (CIRES) concerned with: selection and procurement of suitable instruments, identification of the installation sites, and the installation of field stations. We also describe methods applied to the processing of seismic records and include a summarized catalog of accelerograms recorded to date.
