Seismic landslide data and actual strong motion records are essential data for seismic landslide mechanism research. How to manage these data scientifically and give full play to their scientific value remains a question worth exploring. In this paper, based on the loess landslides induced by seven typical historical earthquakes and the strong motion records of 125 earthquakes from 2001 to 2018 in the Loess Plateau region, a database management system for earthquake landslides and strong motion records in the Loess Plateau was constructed relying on the open-source GIS platform + MySQL database. With a standard and friendly interface and a clear and smooth graphical presentation, the system parameters are easy to obtain. The system not only provides a scientific and convenient platform for managing and applying seismic landslides and strong motion records data but also provides a solid database for studying the mechanism of seismic landslides in the Loess Plateau, so it has a certain reference value for disaster prevention and mitigation work in this region.
