When tableland flows: Insights from the east Patagonian landslide inventory
Original language description
Landslides in volcanic and sedimentary tablelands encompass some of the world's largest subaerial landslide areas, yet the controls on their distribution and dominant landslide types remain unclear. Our landslide inventory across 517,000 km2 of volcanic tableland in extra-Andean Patagonia reveals that, alongside common rotational slides and spreads forming nearly continuous fringes around plateaus, flow-type landslides dominated by earthflows are very common. Most of these flows are concentrated in the highest and most humid western part of the tableland, formerly covered by the Pleistocene Patagonian Ice Sheet (PIS), where they constitute three-quarters of the landslide area. Nevertheless, many of the longest flows (>10 km) are located in the steepest parts of the tableland outside the PIS limits, paradoxically often in the driest areas. This suggests that these flows are inherited landforms originating during more humid Quaternary or older periods. Multivariate statistical analysis highlights that the distribution of flow-type landslides is largely influenced by caprock thickness. Decreasing caprock exposes larger areas of weak sub-caprock units such as sedimentary rocks and volcaniclastics on escarpments, thereby increasing the potential for viscoplastic flows. Future studies will require detailed exploration of the geomechanical properties of weak layers within sub-caprock units to achieve a comprehensive understanding of the lithological predisposition of flow-type landslides in the Patagonian tableland.
