The 2006 Borujerd earthquake occurred in the early morning of 31 March in the South of Borujerd with destruction in Borujerd, Silakhor and Dorood areas of the Loristan Province in western Iran. The centre of the earthquake was in Darb-e Astaneh village south of the Borujerd City. The earthquake measured 6.1 on the moment magnitude scale.
This powerful earthquake shook the entire land of Loristan Province and most areas of Hamedan Province, Markazi Province and destroyed many villages in Khorramabad, Alashtar and Arak County as well. More than 180 aftershocks followed the main earthquake in April, May and June and people had to stay outside for several weeks.
A lighter foreshock happened the night before, and people stayed outside overnight and this reduced the number of casualties significantly. However, the mainshock at 4:47 am on 31 March shook Borujerd, Dorud and other towns and villages on Silakhor Plain for more than 55 seconds.
More than 40 major historical monuments of Borujerd were destroyed by the earthquake and 30% of the historical downtown of the city (2.7 kmª) was ruined or damaged thoroughly. Other monuments damaged by the earthquake include:
- Jame Mosque of Borujerd (900 AD)
- Soltani Mosque of Borujerd
- Imamzadeh Ja'far, Borujerd
- Chalenchoolan Bridge
- Ghaleh Hatam Bridge
