Helping citizen with sinkhole evaluation, samples collected along the sedimentary profile and 3D modelling inside a cavity having reached the surface of the garden and most potentially linked to old underground exploitations of the Lede stone in that part of the city of Brussels

Ongoing work in the framework of the project GEO2KA (funded by a Belgium-Vietnam Research Cooperation Research Call through Belspo). Here below some outreach-communication activities with the students in a school located in Marche-en-Famenne on geohazards aspects (floods, karstic features).

📣Land Subsidence Workshop organised by LASII (UNESCO), GSEU project (EuroGeoSurveys) and hosted by the Geological Survey of Belgium (RBINS/GSB) allowed more than 60 scientists from Europe to present areas affected by geohazards. Details at: https://gsb.naturalsciences.be/land-subsidence-workshop/

A nice GSB fieldwork to collect new ore samples in the -130 m mining galery at the Vedrin mine. Big thanks to the Vivaqua miners, workers and scientists for their incredible help. 31 samples collected and potentially interesting ones with galena, sphalerite, marcassite, ... wait the analyses #CRMA

#GSBNews 📢 Our colleague and raw materials expert Sophie Decrée was interviewed by VRT NWS on the European Critical Raw Materials Act #CRMA and the role Belgium is playing in this strategy. To read the full article see hereafter ->

#GSBnews 📢 As part of the annual CO2GeoNet General Assembly, our colleague Kris Welkenhuysen visited the Northern Lights JV #CCS project near Bergen, Norway. CO2 will be stored at 2600 m depth in the subsurface. Great to see these real-world and large-scale CCS projects coming to life! #RBINS

EuroGeoSurveys has organised the Strategic Research and Innovation Agenda (SRIA) event yesterday afternoon with representatives of DG CLIMA, Euromines and DG RTD. The SRIA was successfully launched during this event with the participation of the European GSO's. #gsbnews #eurogeosurveys #gsbevents
