-release of seismic energy was directly under the city and they were travelling vertically which caused maximum damage to buildings
-very old, 'adobe' buildings, most were built over 2000 years ago and have heavy roofs
-more recent reconstructions had been of low quality because the building code had not been properly enforced
-termites had already weakened some wooden buildings
