Table 1 The scenarios discussed in the text for the 1887 Ligurian earthquake, with fixed source centroid location (\(7.94^\circ\)E, \(43.74^\circ\)N) and focal depth (15 km). The rake angle is adjusted to account for both pure reverse and normal faulting (i.e., with a rake of \(\pm 90^\circ\)). The strike and dip angles are reported together with the Pearson correlation coefficient (PCC) values calculated for each fault scenario relative to the H trace recorded at the Greenwich observatory.
