may have caused preseismic velocity changes in the crust. The original
design of the network had a
high clock accuracy (±
1 ms). S-waves tend to be very clear, and successful 1D velocity model (SIL
model) has been used to locate earthquakes in the area, suggesting relatively simple velocity structure
in spite of active tectonic setting.
