Peak ground acceleration underestimates narrow-band seismic amplification on mountain slopes
Topographic amplification is widely invoked to explain strong shaking and slope failure in mountainous terrain, yet direct field observations remain limited. Here we analyze 24 regional earthquakes recorded by a four-station strong-motion array spanning a ridge crest, a valley bottom, and two contrasting slope facets...
