The region of Sonora is particularly interesting, because the largest historical earthquake (3 May 1887, Mw 7.5) occurred in this province. The town of Bavispe was destroyed during this earthquake (Aguilera, 1888), and the seismic source generated the longest recorded normal‐fault surface rupture (101.8 km) in historic time (Suter, 2006). The major fault zone of this earthquake includes (from south to north) three neighboring segments: Otates (length l=18.9  km), Teras (l...
