We use InSAR and body-wave seismology to determine independent source
parameters for the 6th April 2009 Mw 6.3 L'Aquila earthquake and
confirm that the earthquake ruptured a SW-dipping normal fault with
\~0.6-0.8 m slip. The causative Paganica fault had been neglected
relative to other nearby range-frontal faults, partly because it
has a subdued geomorphological expression in comparison with these
faults. The L'Aquila earthquake occurred in an area with a marked
seismic deficit relative to geodetically determined strain accumulation.
We use our source model to calculate stress changes on nearby faults
produced by the L'Aquila earthquake and we find that several of these
faults have been brought closer to failure.
