The key technologies for Geo-CPS (cyberphysical system) have been developed to resolve pressing problems in relation to geohazards. The main deliverables are an IoT framework, a particle-based simulator, spatial modeling technologies of surface and subsurface attributes, and a 3D visualization platform. The IoT framework is a crowdsensing system for MEMS based ground vibration monitoring. The simulator, based on SPH and DEM solvers, provides a powerful framework for numerical analysis of various geoscience-related problems with high computational speed and accuracy. The 3D visualization platform can transform largescale 3D geospatial data into visualized form in real-time.
