This study analyses intensity duration frequency curves for 31 raingauge stations located in different climatic zones in Chile, including arid and semiarid zones and humid zones. These curves were built using pluviograph records taken from 1962 to 2002. Maximum intensities for each year were obtained,then, for each duration, Gumbel distribution functions were fit with optimum results, from a statistical point of view. Gumbel functions were used for 1, 2, 6, 12 and 24 hours; then, curves were built using different return periods. With all results, maximum intensities were analysed, mainly for I hour and 24 hour, and for a return period of 100 years. The graphical behaviour of maximum intensities showed a slight increase from north to the south; also, some raingauge stations in the semiarid zone showed similar intensity values to southern region stations. On the other hand, raingauge stations located near lakes and dams recorded the highest intensities of their zones.
