Landslide data of Koshi basin was digitized from toposheet maps published in 1960s.

Landslide data of Koshi basin is digitized from topo sheets published in 1990s.

Landslide data of Koshi basin was digitized from Landsat and Googel Earth.

Nepal earthquake of 2015 resulted in activation and re-activation of many landslides in and around epi-center and after shock areas. The landslide inventory was prepared by visually digitizing landslide polygons on Google Earth Pro. The earthquake database contains both pre-event landslide and co-siesmic landslides.

Landslide susceptibility map of Koshi Basin is to identify landslide hazard areas for use during the planning of developmental activities.

Landslide inventory is polygon of every landslide for landslide characterization and analsysis to understand landslide distribution pattern, and identify areas susceptible to landslide events in future. This is important for proper consideration of landuse codes for planning developmental activities.

Earthquake-induced landslide hazard mapping is based on investigations in the Bahrabise–Liping area of the Sindhupalchok District. The information was gathered from existing maps, past published and unpublished reports, satellite images as well as field survey of some important failures. Seismic hazard analysis is a common tool to estimate the expected level of intensity of ground motion related to earthquakes. Seismic hazard is the probability of occurrence of a specified level of ground shaking in a specified period of time at a particular site. In seismic hazard analysis, it is required to infer the source of the future earthquake. To evaluate seismic hazard for a particular site or region, all possible sources of seismic activity must be identified and their potential for generating future strong ground motion should be evaluated. Seismic hazard can be estimated either by deterministic or probabilistic approaches. The hazard can be investigated deterministically when a particular earthquake scenario is assumed, whereas it can be analysed probabilistically when uncertainties in earthquake size, location, and time of occurrence are considered.
