Figure 1. (A) The distributions of tectonic units and earthquakes. (B) The triangles indicate positions of the seismometers. Orange triangles represent Group 1 stations situated in proximity to the ...
The critical role played by accurate seismic velocity measurements in imaging is well documented. Optimal summing of prestack time migrated (PSTM) data depends on accurate seismic velocity ...
Velocity is a fundamental property of rocks that depends on density and elastic moduli. It varies laterally as well as vertically due to the physical-geologic variations of rocks. Velocities are ...
