RT Journal Article T1 Flujos densos en los Valles Calchaquies, Andes Centrales de Argentina T1 Mud flows in the eastern slope of the Central Andes (Calchaqui Valleys), Argentina A1 Barrientos, Celia D. A1 Alonso, Ricardo N. AB The eastern slope of the Central Andes is an interesting geological observatory for the study of mass movements. Giant land-slides, mud-flows, debris-flows and flash-floods occur frequently. During the austral summer season (December to March), Calchaqui Valleys are the theatre of several mud-flows. We have also evidences of several phenomena in the historical time. We report here two localities with past mass movements (San Lucas and Santa Rosa). These localities constitute a site for potential geological hazard mainly during the ENSO (El Niño/ La Niña) years PB Sociedad Geológica de España YR 2001 FD 2001 LK http://hdl.handle.net/10272/9544 UL http://hdl.handle.net/10272/9544 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
