Description:
We present the results of a combined analysis of remote sensing and geophysical ‐ geotechnical
data carried out in the Acque Albule Basin, a sinkhole prone area located close to the city of Roma,
where a wide travertine wedge is present. We carried out geophysical measurements and borehole drillings
over two test areas to image the subsoil where paroxysmal sur fi cial dynamics occur. One site is marked by
subsidence occurring at least since the early 2000s, whereas the other site hosts the “ La Regina ” and
“ Colonnelle ” sinkhole lakes, which discharge sulfur ‐ carbonated waters. The stability of these two sites
threatens highway, railway, and airport facilities, and this study helps to assess the geological hazard. For
example, InSAR and LiDAR data helped de fi ne wide scale subsidence over the last 20 years and previously
undetected small ‐ scale morphologies. Geophysical measurements of the latter revealed shallow and
deep dissolution affecting the travertine and driving sur fi cial paroxysmal events. Both study sites were found
to lie inside a large depression located at the junction between Jurassic carbonate and Plio ‐ Pleistocene units in association with paleo karst morphologies in the travertine deposits and affected by the present ‐ past
spillage of sulfurous waters. Given these elements, multidisciplinary geophysical observations are crucial for
assessing and mitigating the geological risk and guiding land use planning and management.
