Land subsidence-induced risk to urban environments: present-day baseline and future scenarios
SubRISK+ approached its final stage, and the project team organised an international workshop aimed to stimulate the scientific discussion on methods and perspectives on using satellite InSAR and other geospatial data on urban settlements, geology, hydrogeology and population to gather insights into land subsidence-induced risk to urban infrastructure and the resulting socio-economic impacts.

The event featured several international experts who shared their experiences on implementing risk assessment workflows and advanced modeling in major cities and countries of Europe and beyond, plus SubRISK+ lead scientists who illustrated the project methodologies and key results.
The workshop was held online using Microsoft Teams, and participation was free and open to the scientific community, remote sensing and geohazard specialists, stakeholders and the public.
Workshop materials and links to key articles and other resources shared by the speakers are available here (uploading in progress):
