Quantifying the influence of topographic amplification on the landslides triggered by the 2015 Gorkha earthquake

Communications Earth & Environment
Topographic amplification is caused by the interaction between seismic waves and rough terrains. It increases shaking levels on hilltops and could lead stable slopes to the brink of failure.
