The 1985 eruption of Nevado del Ruiz Volcano, Colombia, which resulted in 23,000 deaths, has been studied by South American scientists, sociologists, and engineers, who evaluated the responsibilities and actions of the groups that played important roles before the eruption. The study is based upon interviews of government, scientific, media, and civil defense participants and the detailed perusal of all reports, publications, and newspapers prior to the eruption. This article deals with the actions related to 1) volcano hazard evaluation, 2) volcano monitoring activities, 3) media involvement, and 4) governmental interaction and response.
