Di Filippo and Marcelli (1951)
These workers locate the epicentre of the 1950 earthquake in the 
Campotosto basin on the basis of the macroseismic field and instrumental 
recordings. Through geological observations they estimate the cumulative
 displacement of the Mt. Gorzano fault to be about 1000 m  and hypothesise
that the earthquake may be related to the activity of the fault.

Bachetti et al. (1990)
This paper analyses geomorphic and structural characteristics of the 
SW slope of the Mt. Gorzano - Mt. di Mezzo range. This slope is ca. 1400 m
high and very steep (ca. 45%). Triangular facets are well developed at its 
base along with alluvial fans and glacs of various ages (Early-Late Pleistocene).
Along the slope a N20W trending, 60- 70 SW dipping, normal fault displaces
the bedrock formations of more than 1500 m (see also Calamita et al. 1995).
Several fault scarps are exposed for about 30-50 m which separates remnants of
a land-surface of Villafranchian age (Late Pliocene - Early Pleistocene). In 
addition, palustrine deposits 14C dated at 39,700 3,000 y B.P. are counter-slope
tilted of about 6-7 (northward) testifying the recent activity of the fault. A
seismic event causing surface faulting is claimed by the Authors for the 
formation of the palustrine basin itself and subsequent events
should account for the tilting.

Blumetti et al. (1993)
These investigators adopt and revise most of the observations of Bachetti et 
al. (1990). In addition, the Authors report 
that the glacis deposits at the base of the Mt. Gorzano range are made almost 
exclusively of sandstone derived clasts. Since these deposits lack carbonate 
derived elements the Authors infer that the activity of the fault that made the 
carbonate bedrock formation to be exposed has to be more recent than the 
formation of the glacs deposits, i.e. later than Early Pleistocene.

Cacciuni et al. (1995)
These workers analyse in detail the Quaternary sedimentary setting and 
outline the geomorphic and the fluvial network features of the Amatrice and 
Campotosto basins and surrounding uplands. A morpho-tectonic framework is 
derived on the basis of the above mentioned analysis. The area includes several
 faults, grouped on the basis of the vertical 
offset (>1,200 m; 1,200-500 m; <500 m), which separate uplifted and subsided 
blocks. The major uplifted block is that of the Mts. Della Laga which is bounded 
to the SW by the Mt. Gorzano fault.

Galadini and Galli (2000)
These investigators consider both the Campotosto and Amatrice sources as 
part of the same structure, which they name Laga Fault. For the northern part 
of the Laga Fault (roughly corresponding to the Databases Amatrice Source) 
they estimate a Late Pleistocene vertical slip rate of 0.7-0.9 mm/y.
