Nepal is a high-risk country for natural hazards including earthquakes, floods, landslides, fires and drought. The hazards with the greatest humanitarian impact are earthquakes and floods. Nepal is categorized into three geographical and ecological zones: Terai, hill and mountain areas. The middle hills and higher mountains are highly
susceptible to secondary earthquake effects, such as landslides, which can be exacerbated by excessive erosion of hill slopes and rock falls as well as heavy rainfall.
The most recent high-impact earthquake in 2015 affected all 37 of 77 districts, 14 of them severely, in the hill and mountain areas. It caused almost 9,000 deaths and
displaced approximately 100,000 people
