The seismic movements and their sequels have constituted through time, gravity facts that affect to the population from the socioeconomic point of view. Although for being natural phenomena, it is impossible to avoid them, knowledge of the physical factors produce that them helps to prevent the risks and to their better attention, being diminished the loss of lives and economic resources. the physical vulnerability especially talks about to the location of the slumses in zones of risk and the differences of its structures to assimilate the effects of those risks (WILCHES: 1989:21). This thesis has relation and direct with other areas of the knowledge and their incidence it is anticipated in pedagogical, scientific, theoretical, practical, political, social and economic subjects. The experience in cases of great earthquakes in city, indicates that the catastrophe is directly proportional to the draft status to face it and that the prevention function begins with the fulfillment of a series of requirements of technical order which they can and they must improve when evaluating the well-known and take advantage of the resources available to develop those knowledge from the point of view of the scientific research. Connoisseurs in the matter assure with you found reason that to take place a strong earthquake in the capital of Colombia, the facts would definitively repel in the development by socioeconomic, of the affected region they are not only of the whole Country for being the political center and economic national. The maps of high risk and the disorderly urban growth, especially, in areas in which human groups of the lowest layers are based, show lifted factors of risk with unpredictable sequels of enormous repercussion in the political and social field (the AUGUST TREMORS). 1-3 the social impact The social impact now happens to be one of the preoccupations of scientists of physical the basic areas or, as well as of the social scientists.
