CRUST is an Italian Interuniversity Center founded in 2016 and aimed to promote research and teaching in the field of Seismotectonics. Responsible of CRUST for Messina University is Prof. Barbara Orecchio also member of the Academic Board of CRUST.
  • Scientific cooperation with the St. Louis University focused on the implementation and application of waveform inversion algorithms for seismic moment tensor estimates.

  • Scientific cooperation with Universities of Granada and Barcelona for analyses of seismograms relative to strong earthquakes occurred in the pre-digital epoch.
  • Scientific cooperation with the Institute of Petroleum Geology and Geophysics of Novosibirsk for seismic tomography studies.
  • Scientific cooperation with Malta University on earthquake mechanisms and geophysical research applied to seismic risk mitigation.
  • Cooperation with the Universities of Catania, Parma, Roma Tre and the Institute CNR-ISMAR of Bologna in the frame of Italian National Project PRIN 2010-2011 "Active and recent geodynamics of Calabrian Arc and accretionary complex in the Ionian Sea".
  • Cooperation with the Universities of Calabria and Chieti in the Project INGV-DPC funded by the Italian National Institute of Geophysics and Volcanology and the Italian Civil Protection Department, 2014-2015, "Base-knowledge improvement for assessing the seismogenic potential of Italy".
  • Cooperation with the Aristotle University of Thessaloniki in the framework of the EC Project INTERREG III B ARCHIMED, 2006-2007, “Development of an Information System for Natural Risk Management in the Mediterranean”, SYNARMA.
  • Cooperation with the University of Catania, the Italian National Institute of Geophysics and Volcanology and several private partners in the framework of the Project PO-FESR Sicilia 2007-2013 "Attività di sviluppo sperimentale finalizzata alla riduzione del rischio sismico nella Sicilia Orientale".
