Some subducting slabs bendcausesbending moment normal faults
friction between tectonic platescausesrocks to break along fault lines
when extensional forces tug on the crustcausingthe rocks to split apart along normal faults
So , this 1991 earthquake , while could be due to slab - pull extension , could also be due to extension in the upper part of the downgoing platecausingbending moment normal faults
Fluids can lower frictional forces that hold these rocks in placecausingrocks along the fault to move
