1 Time Domain Moment Tensor & Finite Fault Solution for the Aquila Earthquake (2009/04/06 01:32) Laura Scognamiglio and Elisa Tinti Preliminary results

2 TDMT for Ml>4.0 events Inverted frequencies: Hz Data used: Italian Seismic Netwok

3 Mainshock TDMT solution (2009/04/06 01:32)

4 Finite Fault Solution: Fault geometry Fault dimension: 16 km x 26 km; Subfaults: 2km x 2km

5 Finite Fault Solution: Inverted Strong Motion Focal Mechanism (137°, 49°, -77°) derived from TDMT solution Inverted freq.: Hz; Rupture Velocity = personal comunication De Gori et al. Inferred Seismic Moment=1.6e+25 Best Inverted Rise time = 2.1 s; Best Inverted Rupture Velocity =2.2 km/s

6 Slip distribution: Strong Motion Original discretization (2 Km) Interpolated (0.2 Km)
