Deep reflection seismic method is characterized by high resolution ratio, accuracy and reliability, and is hence an effective technique for geoscience research.

Because of its accuracy in outlining the Earth's subsurface, the seismic-reflection method remains the most important tool in the search for petroleum reserves.

By combining the reflection seismic method with orthotropic piezoelectric composite material (OPCM) acoustic emission (AE) sensor character, a novel SHM technique in civil engineering is proposed.
