| + | * Trying to estimate the local Rayleigh wave velocity by cross correlating different stations. Get a large difference when compared to the velocity estimate from the location of the source (mining explosion). Have to be careful distinguishing between the group and phase velocities. | ||

| * Also looked at a teleseismic event in more detail: using N-1 stations to predict the incident waveform, and then compute the expected waveform at the N-th station and compare with the observed waveform at the N-th station. Assume simple reflection off of a plane, no coupling P-S waves, assumes known isotropic velocity etc. Still gets a very good agreement, but can improve it in multiple ways. | * Also looked at a teleseismic event in more detail: using N-1 stations to predict the incident waveform, and then compute the expected waveform at the N-th station and compare with the observed waveform at the N-th station.
