To meet the objective was used earthquake data occurred between the years 2000 to 2009, data from tectonic plate near to South America and the Apriori Algorithm. As a result of the study it has 4 association rules of interest were obtained with the probability that one of them occurs, the first pattern interest is 'existe-p7-94horas then existe-p7-120horas', 'p7' is the South American Plate.
