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.
