This paper presents a study about the risk of mortality from lightning in the Department of Cundinamarca, Colombia (central Andean region). The study is based on a methodology developed in the United States and presented for the first time in 2015, which establishes a quantitative value of lightning mortality risk through the spatial multiplication of the ground flash density (GFD) and the population density for a given geographic region. A risk map at municipal level for Cundinamarca is prepared and its results are contrasted with the official records of deaths by lightnings.
