INTEGRATED UNDERSTANDING OF SEISMICITY, USING INNOVATIVE METHODOLOGIES OF FRACTURE MECHANICS ALONG WITH EARTHQUAKE AND NON EXTENSIVE STATISTICAL PHYSICS - APPLICATION TO THE GEODYNAMIC SYSTEM OF THE HELLENIC ARC

Abstract: 

Understanding of earthquake physics, from rock fracture to earthquake fault scale, will enhance the quality of life both of European citizens and of vulnerable populations worldwide. The proposal will progressed along parallel and interlinked avenues. On the experimental one will generate unique, well constrained, laboratory data on acoustic emissions (AE) and pressure stimulated currents (PSC) under simulated conditions (stress-temperature) along with a pool of data from the operation of an integrated GPS and seismological network in the front of the Hellenic Arc.

On the theoretical branch will develop new innovative techniques based on modern semi-markovian statistical seismology, modern thermodynamic and generalized non extensive statistical physics [NESP]-superstatistical principles, along with innovative DSP methods (wavelets, neural networks) for both the analysis of laboratory results and seismicity. The latter techniques will support the application of existing robust seismological methodologies of accelerated decelerated seismicity, change of seismicity rates and time dependent stress transfer.

The aim of the proposal is the study of questions arising on the geodynamic behavior of the system as it is developing through seismicity, in a similar way, as with the physics of fracture.

The fundamental questions that will addressed summarized as follows:

  • How does seismicity -or acoustic emissions (AE) and pressure-stimulated currents (PSCs) in rocks- depends on its elementary constituents, i.e. the earthquakes and fractures?
  • How are laboratory observations of fracturing or creep related with geodynamic deformation and what are the accompanying phenomena?
