The deluge worked to loosen a portion of the slopes of the Pichincha volcano, located just west of the city. The landslide, carrying a combination of mud and debris, quickly rushed downhill and overwhelmed the population of the La Gasca neighborhood below. In addition to the mud and debris, torrential rainfall persisted and sent water surging down streets, sweeping away residents, leaving vehicles trapped and homes flooded. At least 16 deaths and 46 injuries are attributed to the mudslide.
