During the week 10-14 November 2025, SubRISK+ team actively took part in an intense series of research dissemination activities, in the framework of three scientific conferences/workshops:

• 5^th Mediterranean Geosciences Union (MedGU), held in-person and online on 10–12 November in Athens, Greece

• XII AIT International Conference – Smart Earth Observation for a Sustainable Future, organised by the Italian Society of Remote Sensing (AIT), and held on 12-14 November in Milan, Italy

• LaSII/GSEU Workshop – Land Subsidence in Europe: from Science to Management, jointly organised by UNESCO’s working group on land subsidence (LaSII) and Geological Service for Europe (GSEU), and held on 13-14 November at the Geological Survey of Belgium, Brussels

At MedGU 2025, Paranunzio et al. delivered an oral presentation on assessing future land subsidence under climate change scenarios, with application to Bologna metropolitan area, which contributed to the Track 17 (Special Session): Land Subsidence: Triggers and Monitoring. This work is the first scientific output of SubRISK+ WP6 on Future Scenarios Analysis, aiming to assess future subsidence risk by 2050 and 2100 under different climate change scenarios accounting for urban population evolution in the 15 metropolitan cities of Italy.

Soon after MedGU, an oral contribution by Cigna et al. was presented at the AIT conference, within the thematic session T3-2 “Natural Hazard”, with a focus on the satellite InSAR-based assessment of present-day land subsidence hazard and risk in the metropolitan cities of Italy. This work was conducted in 2024 by SubRISK+ team as part of WP2 on National scale risk assessment; its core outputs are openly available in digital form within the ‘Control Room’, and described detail in the accompanying report (see DEL2.1 and DEL2.2 in the Deliverables page). The full conference programme of AIT can be accessed here.

Finally, a set of three key scientific contributions were delivered at the LaSII/GSEU workshop (see more details and full programme within LaSII webpage here), with:

• Cigna et al. opening the session on Scientific advantages of drivers, monitoring and modelling of land subsidence with a talk on monitoring land subsidence and its induced risk to urban infrastructure using satellite InSAR in Italy;
• Bonì et al. presenting a poster on InSAR-based assessment of risk levels from differential land subsidence to support sustainable urban land use planning, with application in Emilia-Romagna region, Italy; and
• Tang et al. presenting another poster on coupled 3D flow-geomechanical differential land subsidence modeling with InSAR-based data assimilation in Bologna.

These presentations involved key results from SubRISK+ WP2 and WP3 on national and regional scale risk assessment, and WP4 on advanced modeling at the local scale.

Moreover, in his role of current chair of the UNESCO LaSII working group, Prof P. Teatini opened the LaSII/GSEU workshop along with Dr J. Hollis (Secretary General of EuroGeoSurveys, EGS) and Dr L. Folin-Calabi (Director of the UNESCO Liaison Office in Brussels and Representative to the EU); while Dr F. Cigna participated in the Panel Discussion on “Subsidence data, use it local or go continental?“, together with lead experts from the University of Alicante, the Hellenic Survey of Geology and Mineral Exploration, and the European Environment Agency (EEA).

Overall, this wealthy and productive week of events provided a range opportunities not only to present SubRISK+ project to the scientific community, but most importantly to get together with many national and international land subsidence experts from academia, industry and policy institutions, and discuss this widespread geological process, available monitoring and modeling techniques and their performances, the impacts caused to urban environments, and future research directions in this field.

Newly developed 3D numerical models and land subsidence risk maps were presented by the SubRISK+ team at two scientific conferences in June-September 2025:

• 2025 Taiwan Geosciences Asembly (TGA) – “Climate and Environmental Changes: Emerging Horizons in Earth Sciences“, co-organised by an international team of institutions chaired by the Chinese Geoscience Union in Taiwan, and held on 16-19 June 2025 in Taipei, Taiwan

• Congresso SIMP-SGI 2025 – Le Geoscienze e le sfide del XXI secolo, jointly organised by the Italian Society of Mineralogy and Petrology (SIMP) and the Italian Geological Society (SGI), on 16-18 September 2025 in Padua, Italy

At TGA2025, Teatini et al. delivered a talk on the stochastic approach developed in SubRISK+ to investigate differential land displacements due to groundwater overdraft in the city of Bologna (Italy), as part of the thematic session: 3^rd LAnd Subsidence induced by fluid ExtRaction (LSUB). This work is the baseline for the advanced 3D modeling led by UNIPD within WP4.
See the full scientific program and more information within the conference website.

At SIMP-SGI, two oral talks were presented by the team. In particular, Tang et al. showcased how 3D geostatistics and 3D numerical models are coupled within WP4 to characterize uneven land subsidence in Bologna, Italy; whereas, Goli Raeisi et al. illustrated the experiments carried out within WP3 to test the capability of satellite-based InSAR data to assess differential subsidence risk in the Emilia-Romagna region, Italy.
Both talks contributed to the specialist discussion on Monitoring the Earth for Hazards: Integrating Geology, Geophysics, and Risk Assessment, within session S30.
The full scientific programme of the workshop plus some side events (such as the PhD day), and many other details are available within the conference website.

Two oral talks were delivered by the SubRISK+ team during the Living Planet Symposium 2025 (LPS2025) on 23-27 June 2025, organised in Vienna by the European Space Agency (ESA).

One presentation aimed to present the results of the national scale risk assessment, with a focus on enhancing the understanding of present-day and future urban subsidence risk in Italy based on multi-scale satellite InSAR workflows and advanced modelling (Cigna et al. 2025), while the other focused on the regional scale analysis, with a focus on InSAR-based regional land subsidence risk assessment in the Emilia Romagna region (Bonì et al. 2025). Both presentations contributed to the thematic session B.04.01 Satellite based terrain motion mapping for better understanding geohazards (see full programme: Part 1 & Part 2), held on 24 June, in the framework of Theme B. Climate Action and Sustainability Challenges – Sub-theme 04 Managing Extremes and Environmental Risks.

LPS2025 scientific programme, full abstracts and presentations are available in the dedicated page within the conference website.

SubRISK+ team successfully delivered a poster presentation at the international conference EGU General Assembly 2025 in Vienna (Austria), on 27 April – 2 May 2025.

The work focused on the integration of EO data into land subsidence risk mapping at the regional scale in Emilia-Romagna, which is the core of WP3, and contributed to the scientific discussions of the thematic session ITS1.21/NH13.9 on Integrating Imaging Geodesy and Artificial Intelligence for Natural Hazard Resilience and Disaster Management.
