The magnitude 7.8 Gurkha, Nepal Earthquake in 2015 killed over 9,500 people including surrounding countries. Even after one year, high-resolution ground motion distribution has not been identified due to the small number of seismic observation points. This study develops a new approach to estimate the distribution of earthquake ground motion by integrating remote sensing technology and earthquake engineering. First, visual interpretation of high-resolution satellite images was conducted to estimate building damage in the affected areas. Next, the distribution of Peak Ground Acceleration （PGA） was estimated by use of the fragility function.
