Man-made structures like dams can influence the propagation of seismic waves in several ways. One of the main effects is that these large structures can act as barriers or reflectors for seismic waves, causing them to be redirected or amplified in certain directions. Additionally, the presence of a dam can change the stress distribution in the surrounding rock layers, potentially leading to changes in how seismic waves travel through the ground. Overall, the presence of man-made structures like dams can alter the way seismic waves move through the Earth's crust, which can have implications for seismic hazard assessments and monitoring.
