Being located in central part of the Himalayan ranges, Nepal is regarded as one of the earthquake-prone countries in the region. Earthquake is a major concern of Nepal because of rapid population growth, poor land use planning, precarious settlement patterns, and poorly implemented building code. Earthquakes in Nepal have been reported since 1255 while major earthquakes were recorded in 1408, 1681, 1810, 1833, and 1866, 1934, 1980 and 1988. Recent earthquake of September 18, 2011 measuring 6.9 in Richter scale killed 6 people and injured 30 people in Nepal. There were many roadside slope damages near the epicenter area. To assess the roadside slope damages after this earthquake, a field visit was conducted and a landslide inventory map along the roadside slope was prepared for the most problematic area. For this study, Koshi and Mechi highways of eastern Nepal were selected as study area and earthquake-induced landslides on the roadside slopes were evaluated in terms of characteristics and mode of occurrences.
