Bosi (1975)
In his review on active faults of central Italy he describes for the first 
time the fault scarp of the Cinque Miglia Plain as "likely active" (see Menu 
"Previous Fault Compilations").

Giraudi (1987)
He describes fault scarps displacing late-glacial and post-glacial 
13,000-12,000 years old deposits in the Aremogna and Cinque Miglia 
plains. On the basis of a detailed aerial photo and field survey he maps 
the fault scarps and reconstructs the stratigraphic sequence outcropping 
in the area. According to his mapping the scarps extend for about 10 km, 
with a vertical throw ranging between 0.1 and 4 m (average 1.5 m) and 
have a strike changing from NNW-SSE to NW-SE in the Aremogna 
Plain and in the Cinque Miglia Plain, respectively. Most of the scarps 
are west-facing, and show a uniform slope. This is interpreted as 
evidence of the fact  that the whole fault scarp is evidence for one large 
earthquake occurred after 13,000-12,000 y B.P. The writer also 
observes that the 2000 y long historical catalogue of seismicity does not 
report any large local earthquake so he concludes that the recurrence time 
of the local surface faulting earthquakes should be longer than 2000 y.

Giraudi (1989) and Frezzotti and Giraudi (1989a; b) 
These papers report on some trenches and shallow hand borings 
performed in the southern part of the Aremogna Plain with the aim of 
reconstructing the geological evolution of the Plain and to better constrain 
the behaviour and the age of faulting of the Aremogna faults. Only one 
trench was dug across the scarp, this was located at the Gravare Valley 
(SW side of the Aremogna Plain); here the investigators recognised one 
episode of faulting and dated it by means of radiocarbon dating between 
12850+-200 and 5060+-150 y B.P. On the basis of climatic and 
stratigraphic considerations they narrow the time window of faulting 
between 7500 and 5060+-150 y B.P. They propose also a preferred age 
of faulting: 6000 y B.P. in Giraudi (1989) and 6500-7500 y B.P. in 
Frezzotti and Giraudi (1989a; b).

D'Addezio et al. (2001)
By means of detailed geomorphic, microtopographic and trench 
investigations they analyse the seismic potential of the Aremogna-
Cinque Miglia Fault. They map a 16 km-long up to 6 m-high complex 
fault scarp as composed of two main sections one in the Aremogna plain, 
the other in the Cinque Miglia plain. Both sections are formed by two 
sub-parallel west dipping scarps: the eastern scarp shows a typical 
normal fault geomorphology with a mountain range on the footwall and a 
basin on the hangingwall, while the western scarp produces subsidence 
where high mountain peaks are located and, as a consequence, causes a 
reversal of the present topography. Type of movement is prevalently 
normal although contraddictory evidence for a lateral component was 
found in the Aremogna area. Two trenches opened across the eastern 
scarp in the Aremogna Plain (trenches 1-2), a quarry exposure across the 
western scarp in the Cinque Miglia Plain (trench 3) and the re-
interpretation of the trench data published by Frezzotti & Giraudi 
(1989a; b) are used to show evidence for three normal surface faulting 
earthquakes that were dated at: 800 B.C.-1030 A.D., 3735-2940 B.C., 
3540-5000 B.C. Because part of the age interval defined for the most 
recent falls in the time interval covered by the historical catalogues of 
seismicity the authors analyse which historical events could be 
attributed to this fault: candidates are the 801 A.D. earthquake, which 
produced some damage in Rome, or even the 9 September 1349 A.D. 
event given the uncertainties in radiocarbon dating (the charcoal sample 
could be much older than the hosting deposits). The authors estimated 
an average recurrence interval of 2140-5080 y, a vertical Holocene slip 
rate of 0.1-0.5 mm/y, a 0.3-1 m slip per event and a 6.5-6.8 magnitude 
in the hypothesis that each of these earthquakes ruptured the entire 
length of the Aremogna-Cinque Miglia Fault.
