Seasonal slow landslide displacement is accommodated by mm‐scale stick‐slip events

NJ Finnegan, EE Brodsky, HM Savage… - Geophysical …, 2022 - Wiley Online Library
Like faults, landslides can slip slowly for decades or accelerate catastrophically. However,

Clayey landslide initiation and acceleration strongly modulated by soil swelling

WH Schulz, JB Smith, G Wang, Y Jiang… - Geophysical …, 2018 - Wiley Online Library
Largely unknown mechanisms restrain motion of clay‐rich, slow‐moving landslides that are
