One of the strongest shocks, in October 1966, also centered near the 1970 epicenter. Several inhabitants of the Huacho area were killed, and over 20,000 were homeless in situated along the boundary of two tectonic plates The Western Cordillera Huacho, the most severely damaged village. At the time of of the Andes Mountains rises abruptly east of the city and reaches altitudes of this shock a religious festival (perhaps associated with that 6,100 m only 130 km from the Pacific Ocean. The geology of the Lima region mentioned earlier, established in commemoration of the great reflects the subduction of the Nazca Lima catastrophe in October Plate under the South American Plate 1746) was being held in and consequent uplift and volcanic Callao; several died when activity. The engineering problems related to the geology of Lima concern some churches collapsed. Landslides and huge ground earthquake protective design, foundation problems on unstable soils, cracks were noted along the water supply for a rapidly growing city, Pan American Highway, and solid waste disposal and urban sprawl. over 2,000 houses sustained severe structural damage in Modern engineering practices have been introduced, with seismic design in Lima. the new building codes. Water resource planning together with modern infrastructure construction takes into account the geological setting of this large and important city.

Several inhabitants of the Huacho area were killed, and over 20,000 were homeless in Huacho, the most severely damaged village.
