“…The fault system bounding the eastern flank of the Middle Aterno Valley was roughly depicted, or even completely missing, in several of the pre 2009 L'Aquila earthquake maps (Bagnaia, D'Epifanio, & Sylos Labini, 1992;Bertini & Bosi, 1993;Boncio, Lavecchia, & Pace, 2004;ISPRA, 2009;Vezzani & Ghisetti, 1998). Therefore, the fault system was ignored by the researchers dealing with active tectonics.…”
