Surface tomography
WebDec 22, 2024 · The surface wave energy can be seen in the figure within the frequency band range of the study area (0.7–2.0 Hz). Two nearly complete circles are distributed at different velocity radii ( Figure 3 ), simultaneously indicating clear, multi-mode signals within the Rayleigh wave signals. WebNear-surface geophysics is the use of geophysical methods to investigate small-scale features in the shallow (tens of meters) subsurface. [1] It is closely related to applied geophysics or exploration geophysics. Methods used include seismic refraction and reflection, gravity, magnetic, electric, and electromagnetic methods.
