In this study, we proposed a system that estimates the disaster waste generation caused by active fault earthquakes as soon as possible after a disaster. In this system, seismic intensity information is automatically collected from the Japan Meteorological Agency's website. The system also automatically calclates damage level of each residential building and disaster waste amount of each waste type. Users of system can obtain the detailed generation amount, composition, and spatial distribution of disaster waste in affected cities without complex manual operation. In order to evaluate rapidity and accracy of estimation in proposed system, we applied it for damaged towns by The 2024 Noto Peninsula Earthquake. The results showed that the total amount and spatial distribution of disaster waste could be predicted in each waste type within about 30 minutes of the disaster occurrence. In addition, The result of accuracy evaluation showed the total amount of disaster waste could be calculated reasonably volume.
