- Ground-motion model is:
where PGA is in g, c1 = -2.122, c2 = 1.885, c3 = -1.011, c4 = -0.012 and σ = 0.502.
- Focal depth, h, between 79 and 131km.
- Consider to separate areas of 90∘ to investigate variation with respect to azimuth; find azimuthal
- Find individual attenuation equations for three earthquakes. Note faster attenuation for smaller magnitude
and faster attenuation for deeper events.
