Context: In the last sixty years urbanization processes have increased considerably. In many of them, the number of inhabitants of the so-called "slums" amounts to more than 50% of the population. In addition, they are located in areas at risk. Objective: To determine and evaluate the monthly progression of the Damage Index (ID, in Spanish) of a group of houses located in a hillside area in the “Altos de la Estancia” sector in Bogotá, Colombia, during a period of four months. Method: The houses were classified according to their structural system in six groups: confined masonry (group A); structural masonry (group B); unreinforced masonry (group C); provisional materials (group D); reinforced concrete porches (group E); and prefabricated houses (group F). And we applied the methodology proposed by the Fund for the Prevention and Attention of Emergencies (FOPAE). Results: There was a constant increase in the ID of all groups. However, group C presented the highest values in the last sampling (2.6% of the households had high ID and 0.87% very high). In the other groups the observed ID was lower and no houses were found with records classified as very high. Conclusions: According to the results, dwellings built in unreinforced masonry show a greater degree of deterioration in short periods of time compared to those constructed with other structural systems.
