How can we simulate seismic wave

WebIn general, traditional seismic surface experiments resolved little beyond reflectivity and compressional wave velocity. However, the innovation of time-lapse experiments gives seismic experiments a particular sensitivity to saturation changes. However, the optimal formulation of the simulation and inversion problem is still unclear. WebMap of U.S. Geological Survey seismic stations in the San Francisco Bay Area and 6 seismograms from an earthquake (public domain). We want to find the location, depth and origin time of an earthquake whose waves arrive at the times measured on each seismograms. We want a straightforward and general procedure that we can also …
