ENGINEERING CHARACTERISTICS OF THE 1982 MIRAMICHI EARTHQUAKE RECORDS.
Abstract
An analysis is performed on 14 recorded components from two earthquakes which occurred in the Miramichi region of New Brunswick, Canada in 1982. Three kinds of parameters are considered for the characterization of strong earthquake ground motions, namely response spectra, duration and intensity. These parameters for the two strongest Miramichi components are compared with those for records typically used in engineering design; response spectra are also compared with a typical design spectrum. From the evaluation of these ground motion characterization parameters, it is concluded that the Miramichi records cannot be considered to be 'strong' ground motions, even through peak accelerations are relatively high.
