A focus on the September 1985 Michoacan earthquakes
Summary The severity of damage to Mexico City as a result of the 19 September 1985 Michoacan earthquake was unusual given the city's distance (350 km) from the zone of seismic energy release. To explain the damage many authors have suggested that unusual source or transmission path characteristics contributed to enhanced ground motion in Mexico City. The purpose of this paper is to present a summary of results obtained from data recorded during the earthquake related to possible anomalous source characteristics. It is concluded that although the Michoacan earthquake was a large earthquake indeed, in terms of energy output, spectral content, geometry and source mechanics it was not remarkable or anomalous relative to other subduction zone earthquakes in Mexico or elsewhere. In fact the future may well see a larger earthquake generated along the Guerrero seismic gap which is significantly closer to Mexico City.
