Using Shear Wave Travel Time Correction Surfaces to Improve Regional Seismic Location in China

Focal Mechanism Comparison

Figure 9 - Focal mechanism comparison for Tibet mainshock. Note how the relocations correlate with the trend of the mechanism, especially west of the mainshock. Suggests that surface rupture might not follow actual fault plane at depth.
