It ruptured the Sumani segment of the Sumatran Fault Zone and perhaps the northwestern part of the Suliti segment. The magnitude was given as w 7.5, or s 7.4. Alahan Panjang was damaged in the earthquakes. Right lateral offsets were reported near the town of Solok. Near the Sumani segment, earthquake doublets occurred repeatedly.Source model of an earthquake doublet that occurred in a pull-apart basin along the Sumatran fault, Indonesia Geophysical Journal International 181 1 141–153 2010 Nakano M.
