This page documents research into techniques for interpolating various CyberShake data products, performed by 2024 SOURCES intern Amelia Kratzer.

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

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
