Recently, the study of surface waves has become more frequently used in advanced technical practice, the analysis of which makes it possible to determine the composition of layers and their properties to depths of units as well as hundreds of meters (MASW method).
Seismic hammers, machines with an impact of weights on the ground, or vibrators are most often used as the sources of seismic waves. With the MASW method, passive monitoring of seismic noise and their subsequent analysis is also possible. Passive monitoring of seismic signals is also used to assess the technical seismicity of a given locality (or construction site). For detailed studies of seismicity, the noise level is monitored, which can excite seismoacoustic waves in the rock environment.
