In the rainy season, watch out for landslides and mudflows.
Tips
usage
Standard news/official term for landslide. Often paired with 泥石流 (níshíliú, mudslide/debris flow) in disaster reporting. Shorter colloquial term is just 滑坡 — which also carries the figurative sense of 'sharp decline' (业绩滑坡, 'performance dropped').
