- Ground-motion model is:
where the units of A

_{max}are not given^{15}, a = 0.444, b = -2.254 and c = 4.059 (σ is not given). - Use one site category: firm ground.

^{15}There could be a typographical error in the article since the use of common (base ten) logarithms leads to very large ground motions —
the authors may mean natural logarithms.
