Determining Seismic-Wave Velocity from Travel-Time Curves
One of the main problems of geophysics is the determination of seismic-wave propagationvelocity from travel-time curves. The problem is as follows: let a transient deformation occur on the earth’s surface at some point A at time t = O. This produces an elastic wave, and its arrival time is observed at each point B on the surface of the earth. It is required to determine the propagation velocity of the wave from the known dependence of time upon the coordinates of the points B.
