Parametric information
Parameter Qual. Evidence
Min Depth (km) 2.5 EJ Inferred from earthquake distribution (Ecos-09).
Max Depth (km) 14.5 LD Based on seismological data from Delacou et al. (2004).
Strike (deg) 45 - 90 OD Based on focal mechanism and regional geological data.
Dip (deg) 50 - 85 EJ Inferred from seismologicak and regional geological data.
Rake (deg) 180 - 230 LD Inferred from seismological data (Kastrup et al., 2004).
Slip Rate (mm/y) 0.1 - 1 EJ Unknown, values assumed from geodynamic constraints.
Max Magnitude (Mw) 6.4 LD Based on the largest historical earthquake located in this area (Grünthal et al.
Q-keys: LD = Literature Data; OD = Original Data; ER = Empirical Relationship; AR = Analytical Relationship; EJ = Expert Judgement
