Early Arrival Waveform Tomography: 3D Case Study
Early arrival waveform tomography is a high-end near surface imaging solutions to handle a variety of near-surface problems, especially if large topography variations and strong velocity contrasts are common. The waveform tomography can further improve the near surface velocity model, which shows greater vertical and lateral resolution and reveals a high velocity layer, than travel time tomography. Near surface imaging affects the result of static correction in preprocessing stage. More accurate near surface velocity model, more satisfied the result of static correction.
