SUMMARY:Soutenance de thèse : Vincenzo Schimmenti - Grand amphi\, bâtimen
 t Pascal n° 530 - 23 Nov 23 09:00
DESCRIPTION:Temporal and spatial correlations in earthquake dynamics: physi
 cal modeling and data analysis In seismology\, aftershocks are smaller ea
 rthquakes originating from the destabilised crust in the regions close to 
 a larger earthquake\, the mainshock. In this thesis we study this phenomen
 on from three distinct perspectives. In the first one we unveil the connec
 tions between simple models of aftershocks occurrence and record statistic
 s of stochastic processes. The second approach builds up on the similariti
 es between earthquake sequences and mainshock-aftershocks groups with the 
 creep dynamics of a domain wall expanding in a thin magnetic film. Finally
 \, we use machine learning tools to construct a forecasting method for aft
 ershock occurrence by exploiting measurements of surface deformation comin
 g from Global Positioning System (GPS) satellites. As an addendum\, in the
  last part of the thesis\, we discuss the physics of yield-stress fluids i
 n porous media and its links to the physics of disorder systems and direct
 ed polymers in random media. Jury : Aurélien Decelle\, François Landes 
 (co-directeur de thèse)\, Cécile Monthus\, Alberto Rosso (directeur de t
 hèse)\, Herbert Spohn (rapporteur)\, Jérôme Weiss (rapporteur)
