Size estimates of Earth’s largest terrestrial landslides informed by topographic setting

Popis výsledku v původním jazyce

Landslides regulate the height of mountains by releasing potential energy and reducing topographic relief. Yet, relief also limits the dimensions of small, frequent landslides in turn. But how local topography, lithology, and climate influence the size distribution and hazard of Earth’s largest terrestrial landslides remains unclear. Here we use Bayesian regression to estimate these effects on landslide volume, drawing on a worldwide sample of 411 cases, each involving > 1 km3. Nearly two third of their total volume is volcanic and sedimentary rocks within 50 km of active fault zones, clustered in actively uplifting mountain belts and on volcanic plateaus. Volumetric estimates vary most distinctly with dominant topographic setting, regardless of local relief, general rock type, or contemporary climate. These largely negligible effects indicate that volume scaling statistics fail to capture differing bulk lithological properties, let alone a detection bias due to climatic controls on land cover, weathering, or erosion.
