Resumen:
The Copala earthquake is the largest earthquake to occur in Mexico since the destructive 1985 events. The strong motion data from this earthquake highlights the enormous progress in instrumentation that has occurred over the past 10 years. Hypocentral parameters for the earthquake are listed. The fault plane involved is shallow-dipping plane and strikes parallel to the coast and the subduction zone and dips towards the north. This mechanism is consistent with focal mechanisms that have been observed in numerous previous earthquakes and with observed locations of microearthquakes which define a shallow dip to the subduction thrust. The Copala earthquake and aftershocks on Figure 1 are in the Ometepec seismic gap and appear to be a success for the seismic gap hypothesis.
