The 7th International Conference on Coupled THMC Processes

Home

After Stockholm, Sweden (GeoProc2003), Nanjing, China (GeoProc2006), Lille, France (GeoProc2008), Perth, Western Australia (GeoProc2011), Utah, United States (GeoProc2015), and Paris, France (GeoProc2017), the 7th GeoProc will take place in the city of Utrecht in the Netherlands, on 3-5 July 2019.

The event will maintain traditional approaches to, as well as introducing new breakthroughs in, the study of Coupled Thermo-Hydro-Mechanical-Chemical (THMC) processes in Geosystems – see Flyer_GeoProc2019. With destructive natural earthquakes having increasing impact as global population grows, and with seismicity caused by georesources extraction and geological storage activities becoming increasingly widespread, GeoProc2019 will focus on the key role of Coupled Thermo-Hydro-Mechanical-Chemical (THMC) processes on earthquake and faulting phenomena. Specifically the meeting will address the role multiscale THMC processes in controlling natural and induced seismicity.

Synopsis and Topics

Natural and induced motion on faults, in particular the initiation and propagation of earthquake rupture, involves a wide range of complexly coupled THMC processes involving frictional deformation, heat production, pore fluid pressurization, phase changes, chemical reactions, creep and fluid flow at scales. Recent developments are rapidly advancing our understanding of faulting phenomenon, from brittle versus ductile faulting, to seismic versus aseismic frictional slip, rupture nucleation, coseismic slip, slow slip and tectonic versus induced earthquake rupture behavior. Ongoing progress depends on integrating different research fields and disciplines, including laboratory and numerical experiments with input from field geology, seismology. rock engineering, material sciences and advanced microscopy techniques. The complexity of the coupled THMC processes involved and the vast range of length and time scales that have to be considered is unprecedented. The topics to be addressed by GeoProc 2019 will include:

  1. Slow to fast frictional experiments, theory and numerical modelling
  2. Geophysical observations and interpretation in terms of coupled THMC processes
  3. Empirical and (micro)physically based models of THMC processes in faulting
  4. Role of THMC processes in controlling natural destructive earthquakes
  5. Role of THMC processes in induced seismicity, fault reactivation and landslides

Invitations

This conference will attract experimental, theoretical and modeling scientists, as well as engineers and practitioners in the field of seismic hazard assessment, to come together from different backgrounds to address common scientific issues in fault and earthquake mechanics relevant to tectonically active faults and to fault motion induced by human activities, such a geo-energy production and geological storage of energy and CO2.  Researchers working on any of the above topics are invited to submit abstracts addressing their most recent advances. Invited keynote lecturers will include
