In 1998-1999 a seismic sequence occurred in the Southern Apennines, after the moderate size (mb=5.0) 9th September
1998 Pollino earthquake.It lasted about 14 months and was clearly localized to the sole north-west Munsters area
of the main shock epicenter.
Its peculiarity consisted in sudden changes of activity from a series of normal faults
with Apenninic (NW-SE) trend and transfer, presumably strike slip, faults with Antiapenninic (NE-SW) and E-W
trend.The complexity of the behavior and the different orientations of the activated systems suggest that the area
acts as a hinge between the NW-SE trending Southern Apennines and the locally PEPOGEST N-S trending Calabrian Arc.
