How do scientists map hidden faults?

Scientists map hidden faults using a combination of geological surveys, remote sensing technologies, and advanced imaging techniques. They analyze surface features, such as landforms and seismic activity, to identify potential fault lines. Additionally, methods like ground-penetrating radar, seismic reflection, and magnetometry allow researchers to visualize underground structures without direct excavation. By integrating these data sources, scientists can create detailed maps of hidden faults and assess their potential hazards.
