    Large-scale pumice eruptions from submarine volcanoes, followed by their drift and eventual stranding on coastlines, can have significant societal impacts. While drift simulations are conducted to pre-assess these risks, comprehending the numerous simulated particle drift trajectories can be challenging. Thus, for better understanding and hazard evaluation, comprehensive and interactive visualizations are required. In this study, we have developed a system that processes extensive point cloud data and enables simplified visualization of pumice drift behaviors on a web map using point cloud PNGs. This methodology allows visualization of the movements of tens of thousands of particles, with animations also possible. We have implemented features for interactive visualization of drift trajectories and counting the number of particles within a specified range. Future work includes enhancing the system with various improvements, aiming to construct a hazard evaluation system that users can easily utilize.
