An article in journal of Geophysical Research disputes
the origin of the what has been called the ?Sirente crater?.

The paper discussing this theory is:

Speranza, F., I. Nicolosi, N. Ricchetti, G. Etiope, P. Rochette,
L. Sagnotti, R. De Ritis, and M. Chiappini (2009), The
?Sirente crater field,? Italy, revisited. Journal of Geophysical
Research. vol. 114, B03103, doi:10.1029/2008JB005759
http://www.agu.org/pubs/crossref/2009/2008JB005759.shtml

They concluded:

?Our data show that the Sirente crater and the minor
depressions are simply the results of human activity and
karstic processes, respectively.?

An article that discusses this paper is:

Bondre, N., 2009, Geomorphology: Crater or not? Nature
Geoscience. vol 2, no. 3, p. 166.
