Sinkhole occurrence along the Tyrrhenian margin of the Central Apennines is of great importance
for applied research, land management and civil protection. This study reports on GPS-altimetry
magnetic, gravity, geoelectric, seismic, and soil gas measurements of a rapidly developing sinkhole
near the Guidonia military airport. The measurements revealed an elliptical 2-m depression
elongated 220 m in the NNE-SSW direction with the minor axis of 110 m. In spring of 2013, two
vertical cavities formed in the eastern and northeastern flanks of the depression whose depths and
shapes are rapidly evolving with the formation of widespread fracturing along the same side. The
geophysical observations image the developing sinkhole to a depth of some 50 m, the presence of
the Travertino lithotype around the depression (down to at least 40 m), and the lack of this lithotype
below the lowered area. The sinkhole's evolution appears to be structurally controlled by local and
regional faulting. These results are useful for designing further geophysical, geotechnical and
geochemical studies to monitor the sinkhole's evolution and to assess the hazard it presents in
densely urbanized area.
