where F is the point force (units of N) in the two-dimensional
domain and M is the local earthquake magnitude. Note that the
point force shown in Fig. 6 is calculated from the adopted values
of the parameters shown in Table 4. Since the values were obtained
using an artificial method, the regression equation (Eq. (8)) should
be used carefully. However, when Eq. (8) is substituted into Eqs.
(3) and (4), the influences of the point force and parameter values are greatly decreased due to the elimination of most material properties.
The parameter values only slightly affect the final results of
the proposed model
