Catania 2022


The University of Catania proudly hosted this international event of high scientific importance, welcomed by the Rector, Prof. Francesco Priolo. The 23rd edition of the DRT conference, held in Catania in the splendid setting of the Benedictine Monastery (UNESCO geo-heritage site), an architectural jewel of the Sicilian Baroque, was attended by some 130 scholars from over twenty different countries, most of them in person. It was a fruitful opportunity to exchange and compare ideas, approaches and scientific innovations in the field of rock rheology, tectonics and deformation.

The DRT2022 conference hosted the awarding of the prestigious Henk Zwart medal (IUGS) to Professor Renèe Heilbronner for her important studies in the field of structural geology and microscale deformation analysis during her brilliant career. Prizes were awarded for the best oral and poster contributions of the congress to early career researchers and PhD students.

The hosting team organized both thematic workshops with Italian and foreign colleagues and three pre- and post-congress excursions to the volcanic area of Etna, the Hyblean carbonate platform area, and the crystalline basement of Calabria.

Overall, the numerous feedbacks received from the participants by the organizers were gratifying and made all organizational efforts easier to overcome. A big thank you to all the participants who honored us with their presence, and a heartfelt thank you to the technical and commercial sponsors, the sponsoring bodies and scientific societies, the Regional Department of Tourism, and finally the team of collaborators without whom the success of DRT2022 Catania would not have been possible. 

See you in Barcelona for the next 2024 DRT meeting.

Ad maiora semper,

Workshops and webinars (in person & online)

W2. (6th July – 14:00-16:00) Workshop “Flank stability and structure on volcanoes”: Bonforte A. (INGV Catania) – Di Traglia S. (OGS Trieste). It will be focused on studies, datasets, methodologies, models and, in general, state of the art of the current knowledge about the stability of volcanic edifices in the World. The workshop will last 2 hrs and will be introduced by 3 or 4 invited talks in the first hour, to introduce some methods, models, applications, and then, in the second hour, participants will present some case studies and/or open questions to be discussed together interactively.

W3. (7th July – 9:00-11:00) Webinar “Present-day kinematics of Sicily from a PS-InSAR analysis of Sentinel-1 data”: Henriquet M. (CEREGE, Aix-en-Provence). The Quaternary geodynamics of Sicily is controlled by the slow convergence of the Nubian-Eurasian plates and the rapid retreat of the Ionian slab along the volcanically and seismically active Eastern Sicilian Margin. We processed Sentinel-1 satellite radar images with a Permanent-Scatterer approach to provide an island-wide quantification of surface displacements at a high spatio-temporal resolution over the 2015-2020 timespan. The calculated mean surface velocities along the satellite line-of-sight were converted into the Nubia and ITRF2014 reference frames by using GNSS velocities derived from MAGNET time series. The resulting pseudo-3D velocity field confirms the general uplift of the Nebrodi-Peloritani range (1.5±0.5 mm/yr) and its differential motion relative to mainland Sicily along the Cefalù-Etna seismic zone. The vertical velocity field in the Eastern Hyblean region also reveals a long-wavelength eastward down-bending of the margin, with coastal vertical rates 2-3 mm/yr lower than the Quaternary, and centered on the inferred epicentral area of the 1693 Noto earthquake. The low activity of Western Sicily is, however, in agreement with the previously estimated Quaternary rates. Fast transient processes are also captured over the studied period (2015-2020), notably the tectono-magmatic activity of Mount Etna, as well as gravitational instabilities and anthropogenic ground subsidence all over Sicily.

W4. (6th July – 9:00-11:00) Workshop “Quantitative microstructural analysis”: Ortolano G. (University of Catania) – Visalli R. (University of Catania). The workshop intends to furnish skills about informatic instruments, use of devices, and semiautomated workflows able to facilitate the quantitative restitution of mineralogical, compositional, and fabric arrangement of rocks at the microscale. This result will be achieved by the combined use of two ArcGis based package tools, namely: a) The Quantitative – X-Ray Map Analyzer (Q-XRMA), based on the statistical processing of X-ray images, able to recognize the minerals and sub-mineral phases, potentially calibrating each pixel of the classified images; b) The Micro-Fabric Analyzer (MFA) useful for the quantitative extrapolation of rock microstructural features, that takes advantage of both of the characteristics of the X-ray images and the optical images features. The Q-XRMA/MFA combined effects allow thus quantifying fabric parameters subdivided per mineral type, automating the numerical fabric data extrapolation at the thin section scale in a GIS environment.

W5. (5th July . 14:00 – 16:00) Workshop “Virtual outcrop & 3D models”: Fazio E. (University of Catania) – Thiele S. (Freiberg) – Lanzafame G. (University of Catania).

Part 1 – Aerial survey & virtual structural geological mapping (Fazio E.): a brief introduction about aerial images acquisition up to the recognition of geological structures and their orientation on virtual outcrops will be made. A workflow through the various steps consisting of drone planning mission (PiX4D free software), passing through 3D virtual outcrop reconstruction (Agisoft Metashape) to virtual structural-geological analysis (GeoVis3D) will be shortly delineated.

Part 2: Mapping cliffs with UAVs and hyperspectral cameras – challenges, advances and opportunities (Thiele S.): cliffs present spectacular and revealing geological exposures for detailed and spatially continuous structural mapping, but are difficult to investigate in detail due to access limitations and safety concerns. Uncrewed Aerial Vehicles (UAV) and Structure from Motion Multi-View Stereo (SfM-MVS) workflows provide a powerful new tool for mitigating these access issues, but have required the development of a new generation of quantitative, objective and reproducible digital mapping methods. This session will cover developments in this area, including: (1) fusing hyperspectral data and digital outcrop models for enhanced lithological and structural mapping; (2) semi-automatic approaches for delineating structures and contacts in dense 3-D point clouds, and; (3) methods for estimating 3-D orientation (strike and dip) and associated uncertainty. Finally, implementations of these methods in CloudCompare and the hylite python package will be demonstrated.

Part 3: Computed microtomography and image analysis: 3D investigations at micron scale (Lanzafame G.): this part of the workshop aims to show the main techniques of computed microtomography and image analysis to unveil the 3D structure of geologic materials at micron scale and to retrieve, from 3D images, qualitative and quantitative information about the phases composing the investigated materials. Required software: ImageJ (or Fijii) available at
