The Walloon government has tasked the Geological Survey of Belgium, together with its partners (UMONS, ULiège, and EPI Ltd), with conducting new large-scale geophysical surveys across Wallonia as part of the Walloon Recovery Plan. The WALSCAN project aims to improve the characterization of the region’s deep geothermal potential and will involve approximately 400 km of seismic line acquisition in three key areas: Charleroi, Liège, and Verviers/Eupen. Scheduled for early 2026, the seismic campaign will focus on detecting Dinantian limestone formations at depths ranging from 1.5 km to 4 km in densely urbanized zones, corresponding to areas with high energy demand. The WALSCAN team is responsible for the campaign’s preparation, supervision, communication, and data interpretation.
