Seismic data refers to information collected from seismic waves generated by natural events, such as earthquakes, or artificial sources, like explosions. This data helps scientists understand the Earth's internal structure and behavior by analyzing how these waves travel through different materials. Seismic data is crucial for various applications, including earthquake research, oil and gas exploration, and geotechnical engineering. By interpreting this data, researchers can assess risks, locate natural resources, and design safer buildings and infrastructure in areas prone to seismic activity.
