This paper presents a PSHA for Colombia, using data since 1960 until 2010, covering an area from 80° W to 70°W longitude and 1°S to 15° N latitude. Recurrence laws and seismic hazard curves were calculated for 2° by 2° areas. There are areas without enough data to obtain a slightly acceptable recurrence law. After that, hazard curves were calculated using Fukushima and Tanaka (1990) attenuation relationship. Finally a peak ground acceleration map was developed for Colombia. There are zones that, from a probabilistic point of view, it is not possible to assign any value. Assessments have been done mean an algorithm developed by author.
