Time Domain Moment Tensor & Finite Fault Solution for the Aquila Earthquake (2009/04/06 01:32) Elisa Tinti and Laura Scognamiglio Preliminary results, Roma 28/04/2009

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

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

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

Finite Fault Solution: Only Strong Motion inverted Focal Mechanism (140°, 49°, -90°) Inverted freq.: Hz; Moment=1.8e+25 Rise time = 1.9 s; Rupture Velocity =2.3 km/s

Inverted frequencies: Hz Rise time = 1.9 s STF Triangular function Moment: Rupture Velocity =2.3 km/s Focal Mechanism (140°, 49°, -90°) Finite Fault Solution: Strong Motion & GPS inverted Gps data given by Cheloni et al.
