During the southern-hemisphere summer months of January and February 2013, local but very intense rainfall events caused a number of debris flows in the Andes Main and Frontal ranges of central Chile and Argentina at about 32-34º S. The flows were mainly triggered in the Maipo and Aconcagua valleys (Chile), concentrated in two distinct rainfall events, and along the Mendoza River valley (Argentina) in a more distributed manner. The flows caused serious disruption to the international road infrastructure and high impact to the population, mainly due to potable water supply cut offs to major cities. In this short paper we document the location and field observations of these events and describe their impacts to society.
