GNGTS 2015 S essione 1.1 Fig. 2 reports s��� ����������� ������� ������� �� ��� ���� ��� ���� ���������� ����������� ome preliminary results related to the July 19, 1865 earthquake (epicentral intensity I 0 IX EMS, M w 5.1) occurring along the Moscarello fault, which was followed the month later by another strong shock striking the S. Tecla fault (I 0 VIII EMS, M w 4.6). We calculated the ∆CFS ������ �� ��� ���������� ����� �������� �� ��� �� ����� ����� ����������� caused by the Moscarello fault (source) on the S. Tecla fault (receiver). Results are reported as areal distribution at a depth of 0.4 km and along two vertical sections related to a receiver fault with dip-slip (Fig. 2a) and right-lateral strike-slip (Fig. 2b) kinematics. We observe that the southern segment of the S. Tecla fault which ruptured during the August 19, 1865 earthquake, falls within the lobe with increase of stress (red areas), where the rupture is favored. Fig. 3 – Distribution of the ∆CFS ��� �� ��� ���������� ����� �� �������� ��� �������� ������ ������ ������ ��� ����� due to the Moscarello fault by adopting the regional PP2001 stress field. The areal distribution is calculated at a depth of 0.4 km. Maps and vertical sections are related to optimally oriented a) normal faults and b) strike-slip faults.
