Procedure

Selection of Sites

  • To start, I selected 4 sites, all in the basin, that formed a 10km by 10km square inside which there was at least 1 site to interpolate. This way I could compare the simulated values for that site to the interpolated to check the accuracy of my interpolation.
    • 1st chosen area: USC as there are three sites on the exterior for 1D linear interpolation and two sites on the interior for 2D linear interpolation
    • Square formed by sites S345, S387, S389, S347
    • 2nd chosen area: CSDH
    • Square formed by sites S385, S429, S431, S387
  • Next, I selected two locations where some of the sites were not in the basin, to test how different velocity structures may affect the accuracy of the interpolation.
    • 1st location: STG
    • Square formed by sites S491, S632, S634, S593
    • 2nd location: SGRTT
    • Square formed by sites S437, S478, S480, S439
