Short summary
La Paz, Bolivia, experiences frequent damaging landslides. We quantify creep before and after the city’s largest modern landslide using spaceborne InSAR. Creep of ancient landslide deposits increased in rate and extent following failure and extended into adjacent intact materials. Accelerated steady-state creep reflects complex post-failure stress redistribution. Landslide risk in La Paz, which is underlain by many large ancient landslides, may be even greater than previously thought.
