The 23 August 2016 M=6.2 earthquake struck between the sites of the 1997 M=6.1 Umbria-Marche shock to the northwest, and the 2009 M=6.3 L’Aquila shock to the southeast. This leaves potential gaps, at least since 1859, between the recent quakes, where another M~6 shock could conceivably strike. (Annotated from an INGV map).
