History and Background
Due to the substantial planning and development of underground space for transportation (e.g., tunnel, pipeline), resource extraction (e.g., oil and gas, geothermal energy, mine) as well as the energy and waste storage (e.g., CO2, nuclear waste), the risk of both natural fault geo-disaster (e.g., earthquakes) and man-made geo-disaster (e.g., induced seismicity) is becoming increasingly relevant, as they may jeopardize the safety of underground facilities and cause immense economic losses. Fault geo-disasters refer to the catastrophic natural earthquake-induced failure of underground structures that occurs at fault fractured zone or near-fault area. If the triggered displacements along some of the pre-existing faults exceed certain threshold, the safety performance of subsurface infrastructure may be compromised. The static stress changes in the near field of the causative fault and the passage of seismic waves that are radiated from the mainshock in remote areas both can affect the stability of caverns/tunnels/shafts/pipelines of the underground space system. In addition, many of the underground activities involving tunnelling, mining excavation and liquid/gas injection and/or production from subsurface reservoirs, result in stress transfers, pore pressure perturbations and thermo-poroelastic responses, which may weaken and reactivate existing faults and induce man-made earthquakes. With the frequent occurrence of global extreme earthquake events and large-scale engineering construction, the frequency and scale of fault geo-disasters and induced seismicity have increased. Therefore, it is urgent to build a global communicating platform for academic and industrial communities to jointly ensure the development of fault geo-disaster and induced seismicity assessment and mitigation for subsurface infrastructure, direct the development of geological resources and energy, and strengthen the awareness of global geo-environment protection.
Aims and Perspectives
Therefore, based on the above-mentioned demands, it is urgent to establish a committee on Fault Geo-disaster and Induced Seismicity in the framework of the ICGdR (International Consortium on Geo-disaster Reduction). The main objectives of this committee are to: (1) clarify the characteristics of fault activation, rock damage and underground structure failure during natural geo-disaster and man-made geo-disaster; (2) develop seismic monitoring and investigating technologies for fault geo-disasters and induced seismicity; (3) design and develop advanced laboratory unit and model experiment technologies to reveal the triggering mechanisms and quantitative parameters of fault geo-disasters and induced seismicity; (4) establish efficient numerical simulation methods to predict the spatial and temporal development of fault geo-disasters and induced seismicity; (5) commit to the fusion and analysis of massive data and the interactive development of virtual reality to provide the seismic risk evaluation and early warning methods for fault geo-disasters and induced seismicity; (6) provide the best scheme for seismic resilience design of underground structure and induced seismicity control. The committee also encourages all participants to facilitate tight cooperation between international organizations, global stakeholders, local and regional governments, universities and scientific academies, and advanced enterprises.
