The 1909 Silakhor earthquake occurred in Silakhor plain (in the south of today's Borujerd County), Persia (modern day Iran) on January 23, 1909. Around 8,000 fatalities were caused directly from the magnitude 7.3 earthquake. An indefinite number of aftershocks continued for six months after the main shock. The section on this fault ruptured was the same as the main rupture zone of the 2006 Borujerd earthquake.[2]

[edit] Background
Occurring on the local Dorood Fault, the tremor caused 40 kilometres (25 mi) of visible surface faulting was recorded on the fault.[3]
[edit] Damage and casualties
60 villages within the region were either completely destroyed or damaged beyond repair. Casualties were extensive, occurring in 130 individual villages.[3] However, damage was contained within a 40,000 square kilometres (15,444 sq mi) area. 8,000 were killed in this sector along with several thousand animals.[4]
Damage was worst within the epicentral area (Silakhor Valley) and surrounding valleys populated by domestic tribes. Signs of ground failure and landslides was evident for another −-500 kilometres (−6 mi) southeast of the epicenter.[4]
