3 Outline of the NOFEAR project 1. Motivation 2. Methodology 3. Anticipated results

4 Earthquakes (EQs, red) and landslides (blue) threaten our continent. http://www.seismo. /flyers/Mediterrane an.html 1.Motivation

5 Friction, fracture and geometry are the keys to understand the physics of EQs (and landslides*). Destructive EQs nucleate at 7-25 km depth so are investigated remotely via seismology. * addressed in NOFEAR, not in this interview because of time limitations.

6 This “indirect” approach (seismograms, GPS, etc.) allows limited understanding of EQ physics. Earthquake forecasting models (probability that a mainshock may occur in terms of hypocentre location, magnitude and time) call for a sound physical basis. BUT

7 The “direct” approach of NOFEAR unifies and theoretical studies to enhance our knowledge of earthquake physics, from rupture nucleation to arrest. NOFEAR main by-product will be the systematic investigation of EQ (and landslides) precursors (seismic, physical, chemical and electromagnetic). Field = fault geometry Lab = friction and rupture laws 200 m 2 cm

8 To achieve these goals, NOFEAR exploits the most powerful and versatile EQ simulator installed worldwide: SHIVA = Slow to High Velocity Apparatus... Di Toro et al., Rend. Lin., 2010; Niemeijer et al., JGR 2011; Violay et al., EPSL 2013; Smith et al., Geology, 2013: Fondriest et al., Geology, 2013… 1 m

9 …and the expertise of the Team I built thanks to USEMS, plus the resources at the Geosciences Dept.* in Padua and at INGV* in Rome. *Best Italian Earth Sciences Academic & Research Centers according to the 2013 evaluation of the Italian Ministry of Education, University and Research. Geosciences Dept. INGV USEMS research team in 2010

10 2. Methodology a) Experiments to determine friction and rupture laws… Di Toro et al, Nature, 2004; 2011; Di Toro et al., Science, 2006; Nielsen et al., GJI, 2010; Spagnuolo et al., subm… ROCK ANALOGUE RUPTURE EXPERIMENTS: UNIAXIAL PRESS REAL ROCKS FRICTION EXPERIMENTS: SHIVA FRICTION LAW 20 mm 20 cm

11 and to investigate precursory events (AEs, physical, chemical, etc.) to main frictional instabilities (EQ nucleation). Slip (m) Di Toro et al., 2010; Spagnuolo et al., subm.; Scarlato et al., 2013; Tisato & Quintal, GJI, 2013 PHYSICAL PROPERTIES MODULE Shear stress (MPa) 50 mm Experimental fault Acoustic emissions, gas emission, attenuation and elastic moduli, etc. Slip rate (mm/s)

12 b) Field studies to quantify the geometry of natural faults (natural faults are not as small and smooth as experimental faults). Di Toro et al., Science, 2006; Bistacchi et al., PAGEOPH, 2011; Fondriest et al., JSG, 2012; Smith et al., Tectonophysics, 2013 Generation of synthetic fault surfaces to use in EQ modeling REMOTE SENSING (DRONE) REMOTE SENSING (LIDAR) 200 m SYNTHETIC FAULT SURFACE
