A combination of measurement scales, including remote sensing and field investigations are utilized to create databases of both natural and artificial environmental and topographic changes that are associated with disasters. At the same time, new disaster investigation and analysis methods are developed and advanced, the integrity of watersheds and hydrologic structure are examined, disaster condition models, three dimensional geology models, substitute water source investigations and evaluation methods and a modular expert disaster monitoring system are developed and strategies to prevent subsidence in soft and hard geologic stratums are designed. Finally using an effective, nationally integrated set of environment and soil data, the safety factor of slopes adjacent to major roads are increased and the value of remediate structures are assessed.

With civil engineering, remote sensing image analysis, AI data processing, and 3D-GIS as core techniques, our group produces the basic data required for natural disaster risk analysis, which is essential to risk model upgrading and to disaster prevention planning of a city and infrastructures. Our R&D and services include:
1) High-resolution satellite image processing.
2) Efficient production for high-resolution digital terrain model and BIM building attributes of the metropolitan area.
3) Deep learning based algorithm on wide area natural disaster risk data analysis.
4) Probability assessment of fault activity and 3D-GIS environmental geological database.
5) Interdisciplinary oversea cooperation on development of natural hazard analysis, exposure and loss evaluation technologies, provide the value-added data services for domestic and abroad insurance or construction industries.

We focus on revealing seismic hazard to buildings and infrastructure facilities of the society, private enterprises and government sectors. Our service provides suggestions and assistance to designate hazard mitigation plan of earthquake impact. Fields of our R&D tasks include (1) primary and secondary hazard from earthquakes, i.e. ground motion, aftershock, tsunami, landslide, liquefaction, etc.; (2) seismic hazard analysis for infrastructures; (3) potential impact of earthquake for carbon capture and storage sites; (4) business continuity plan (BCP) of resisting earthquake impact; (5) real-time earthquake monitoring and analysis system.

The major task of Slopeland Hazard Mitigation Group is to integrate innovative earth observation technology, remote sensing interpretation, IoT, and mobile mapping and survey which developing both susceptibility assessment and early warning system for sediment-related hazard (landslide and debris flow) from the regional, catchment, and slope scale. Our study aspect focus on satellite-based InSAR analysis, mapping and zoning of landslide geologically sensitive area, debris flow risk assessment and risk management, intelligent wireless sensor development, e-survey, and inspection technique, AI information platform application, detailed geo-hazard assessment model, and numerical simulation approach. The presented research topic may serve as the foundation for assessing the threat and establishing prevention measures in natural hazard mitigation in the future.
