- Abstract
- The September±October 1997 seismic sequence in the Umbria±Marche regions of Central Italy (main
shocks on September 26, Mw 5.7 and 6.0, and on October 14, Mw 5.6) left signi®cant ground eects,
which were mainly concentrated in the Col®orito intermountain basin. These eects included surface
faulting, ground cracks and settlements, rock falls, slides, hydrological and gas anomalies. The
distribution and size of ground eects has proved useful for (1) de®ning the epicentral area and the
location of the causative fault; (2) complementing the intensity pattern from damage distribution (this
can be very useful in poorly inhabited zones); (3) integrating or testing the intensity assessment of many
historical events, in order to obtain a better evaluation of the magnitude from intensity data. Of special
interest was the observation of surface ruptures generated along segments of a system of normal faults
already mapped as capable, with end-to-end lengths of 12 km and maximum displacements of 8 cm.
Many pieces of evidence con®rm that coseismic slip was not a secondary, gravity-induced, phenomenon,
but had a tectonic origin. Detailed descriptions of surface faulting for moderate earthquakes are not
common, being easily missed or misinterpreted; however, in this paper we emphasize that surface
faulting due to the 1997 event can be used to infer the threshold magnitude for surface faulting in
Central Apennines, allowing to calibrate palaeoearthquake size from fault osets as seen in trench
investigations. (literal)
