Dual control of fault intersections on stop-start rupture in the 2016 Central Italy seismic sequence

- 3 M > 6 earthquakes in Central Italy are a uniquely well-observed seismic sequence.
- Pre-existing fault structures controlled the extent of rupture in each event.
- Fluid diffusion along these structures may have determined timing of sequence.
- Dual control of structure on stop-start rupture in seismic sequences may be common.
