Many one and two-storey buildings which were damaged had been constructed using materials which could not resist earthquakes, based on a mistaken belief that these buildings would be unaffected by any earth tremors. Consequently, the following year, the Colombian government passed a new building code ( es, Código Colombiano de Construcciones Sismorresistentes) into legislation which required the construction of dwellings capable of resisting earthquakes.
The Colombian Seismic Network was also created, tasked with monitoring seismic changes.
