Geoinformatics plays a critical role in earthquake studies by integrating spatial data, advanced technologies, and analytical tools to understand, monitor, predict, and manage earthquake hazards and their impacts. It combines Geographic Information Systems (GIS), Remote Sensing, Global Navigation Satellite Systems (GNSS), and spatial modeling to support all phases of earthquake disaster management, from preparedness to mitigation and recovery. One of the most important roles of geoinformatics in earthquake studies is seismic hazard assessment and zonation. GIS is widely used to integrate geological, geophysical, and seismological data such as fault lines, plate boundaries, historical earthquake records, soil type, and ground motion parameters. By overlaying and analyzing these spatial datasets, earthquake-prone zones can be identified and classified into different risk levels.
