Harmonized earthquake-induced landslide hazard assessment in cross-border region – CRISIS project

CRISIS project (101004830 - CRISIS - UCPM-2020-PP-AG) aims at improving the disaster and emergency management through building a harmonized and efficient system for risk assessment of basic services and transport infrastructure at the cross-border region between N. Macedonia, Albania, and Greece the targeted cross-border region. The main project activities include: (1) Cross-border multi hazard assessment; (2) Needs assessment; (3) Cross-border multi-risk assessment; and (4) Development of cross-border web base platform for risk assessment and management. This paper presents the harmonized approach for landslide susceptibility and hazard assessment in the targeted cross-border region. The European ELsusv2 initiative is selected as a harmonized approach for regional landslide susceptibility mapping for the area study. An analytical relationship is used to assess the permanent slope displacement for different earthquake scenarios. The final product of the landslide hazard zonation is presented by GIS maps showing the expected permanent displacements for pre-defined earthquake scenarios. The presented approach for the cross-border region is a simple tool used to recognize the hazardous areas, where only limited geomorphological, geological and seismological datasets exist. The landslide hazard maps will contribute to the definition of the risk for critical infrastructure at regional scale due to landslide triggering in the project. Overall, the CRISIS project and the landslide hazard zonation provided for the cross-border region will contribute towards better long-term risk mitigation strategies in each of the countries involved in the study.
