Generation of sufficient soil pore-water pressure to trigger failure of rainfall-induced landslides depends on the combination of antecedent soil moisture and the intensity and duration of infiltrating rainfall during the triggering storm. Precipitation extremes and volatility are both projected to intensify in the future due to climate change, particularly in California (USA), which already experiences considerable interannual variability relative to the rest of the country as well as distinct seasonality. The effects of these changes on rainfall-induced landslides are not straightforward. Nominally, increasing precipitation intensities lead to more landslides, however above a certain th...
