Description:
This study is focused on amplification effects observed at an on-fault station, FAGN, near L’Aquila.
The difference in amplitude, compared to nearby stations, is extremely large for some particular events and
neigligible for others of the same seismic sequence.
FAGN is located on the S. Demetrio fault (Vezzani and Ghisetti, 1998) and the presence of the fault zone
beneath the station could play a role on the observed amplifications (Davis et al., 2000; Cultrera et al., 2003;
Karabulut and Bouchon, 2007).
The fault-guided propagation effect is investigated through numerical modeling and analytical solutions by
Ben-Zion and Aki (1990) and Ben-Zion (1998).
