Project description
Cutting-edge approach to investigate Quaternary seismic reactivation with greater precision
Intraplate seismic surface rupturing may unexpectedly occur in faults thought not to be active, posing significant risks worldwide and affecting regions in Africa, Australia, Europe and North America. Climate change and induced surface processes changes can alter surficial stresses, impacting faults’ seismic cycle patterns, deformation rates, and even kinematics. The Marie Skłodowska-Curie Actions programme supports SEISMO-REACT, a project aiming to investigate older faults’ Quaternary reactivation and seismicity patterns in southwest Portugal, an ideal and intriguing natural laboratory. SEISMO-REACT will combine active tectonic studies with an innovative geochronology method (luminescence and electron spin resonance) to investigate fault gouge geochronology and date seismicity. If successful, the proposed approach could be applied to other intraplate settings, enhancing seismic hazard analysis and natural disaster management.
Objective
SEISMO REACT aims to investigate Quaternary active faults, surface deformation, and the reactivation of large potential seismic sources in an intraplate setting, by combining data from geology, geomorphology, geophysics, and geochronology, in particular by applying a new method using trapped charges (Luminescence and Electron Spin Resonance) to investigate fault gouge geochronology and timings of fault activity. The seismogenic reactivation of older structures in an intraplate setting is a known tectonic condition worldwide, impacting Europe, Australia, Africa, and North America. Furthermore, it is known that fault stress changes can be induced by climate change processes and seismic triggering, interfering with the tectonic strain and impacting seismic cycle patterns, deformation rates, and even the structure’s kinematics. Altogether, these questions prompt an understanding of the occurrence of reactivation episodes and their timings. Hence, investigating the timings and possible regional mechanisms and the propensity of reactivation of seismic sources at intraplate settings is a pertinent research project. The targeted study area is Southwest Portugal, an area with quaternary deformation and younger and older structures reactivated, which is an ideal natural laboratory. The methodology developed if successful can be transferable to intraplate settings in Europe and elsewhere, investigating Quaternary activity in reactivated inherited faults with long recurrence periods. Results can be integrated into seismic hazard analysis and natural hazards management, boosting society’s resilience in a world gradually exposed to stronger and more frequent climate events, a possible mechanism for impacting regional changes in the fault stresses. SEISMO REACT will be based at the Institute Dom Luiz, University of Lisbon supervised by Prof Custódio, and a secondment in the Leibniz Institute for Applied Geophysics, supervised by Prof Tsukamoto regarding the ESR geochronology.
