Parametric information
Parameter Qual. Evidence
Min Depth (km) 0 LD Fault affects late Quaternary deposits;Geomorphic expression;Paleoseismic trench
Max Depth (km) 25 EJ Based on average dip, and max. seismogenic depth
Strike (deg) 138 - 166 LD One-sigma range of strike of mapped surface trace
Dip (deg) 50 - 65 EJ General estimate from mining & seismic-reflection data, & hypocenter of large eq
Rake (deg) 284 - 312 AR Shear direction resolved for evaluated dip and strike range from stress tensor
Slip Rate (mm/y) 0.03 - 0.06 LD Converted from published vertical deformation rate
Max Magnitude (Mw) 7.1 ER Based on length of mapped surface trace, truncated at 55 km
Q-keys: LD = Literature Data; OD = Original Data; ER = Empirical Relationship; AR = Analytical Relationship; EJ = Expert Judgement
