DESCRIPTION:Prof Eleonora Rivalta (University of Bologna)\nAbstract\nMagm
 a propagates in brittle elastic rocks by diking\, which is a form of hydra
 ulic fracturing. Dikes are voluminous (>10^5 m^3) magma-filled cracks orie
 nted roughly perpendicular to the least compressive elastic stress axis\, 
 driven by their buoyancy pressure or by external stress gradients such as 
 those induced by the flanks of a volcano. Prof Eleonora Rivalta will illu
 strate high-quality geophysical observations of recent dikes\, focusing on
  deformation and seismicity. Next\, she will illustrate the models her stu
 dents and herself have developed over the years\, first in 2D and\, more r
 ecently\, in 3D\, as well as their strategy to forecast future magma pathw
 ays and the opening location of future eruptive fissures.\n \nShort Bio\n
 Eleonora Rivalta is a senior scientist at the German Research Centre for G
 eosciences in Potsdam and an Associate Professor at the University of Bolo
 gna in Italy. She graduated from the University of Bologna (both a Master'
 s and PhD in Physics). She did post-docs at the University of Hamburg and 
 in Bologna and spent a long research stay in Stanford with Paul Segall. Ne
 xt\, she worked as a lecturer at the University of Leeds\, UK. Finally\, s
 he moved back to Germany where she started her ERC Starting Grant group on
  the physics of magma propagation. Her main interests are the mechanics of
  magma propagation by diking\, especially modelling the influence of crust
 al heterogeneities and the external stress field on the expected magma tra
 jectories\, and simulating the expected geophysical observations.\n\nSandw
 iches will be provided at the end of the seminar\n
