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:
Apart from UN agencies e.g. UNESCO and UNICEF, there are other international agencies functioning in the field, including MSF, Caritas Italy, Operation Mercy, ACH Spain and ACT Netherlands. [5]

The 1915 Pleasant Valley earthquake occurred at 22:53:21 on October 2 in north-central Nevada. With a moment magnitude of 6.8 and a maximum Mercalli intensity of X (Extreme), it was the strongest earthquake ever recorded in the state.
The 1909 Borujerd earthquake also known as Silakhor earthquake occurred in Silakhor plain, Persia on January 23. 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.
The 1930 Salmas earthquake occurred on May 7 at 01:34:26 IRST in West Azerbaijan Province, Iran. The earthquake, which was among Iran's largest, measured 7.1 on the moment magnitude scale and had a maximum Mercalli intensity of IX (Violent). A damaging foreshock occurred fifteen hours prior to the main event and served as a warning to the people that felt it strongly. Reports from seismologists and seismological organizations indicate that up to 3,000 fatalities may have occurred in northwest Iran and southeast Turkey.
The 1980 El Asnam earthquake occurred on October 10 at 13:25:23 local time with a moment magnitude of 7.1 and a maximum Mercalli intensity of X (Extreme). The shock occurred in the Algerian town of El Asnam. The shocks were felt over 550 km (340 mi) away, with the initial earthquake lasting 35 seconds. It was the largest earthquake in Algeria, and was followed three hours later by a magnitude 6.2 aftershock. The earthquake created about 42 km (26 mi) of surface rupture and had a vertical slip of up to 4.2 m (14 ft). No foreshocks were recorded. The earthquake was found to have occurred very close to the epicenter of the 1954 Chlef earthquake using joint epicenter determination techniques. It occurred at a previously unknown reverse fault.
Striking southern Italy on September 8, the 1905 Calabria earthquake had a moment magnitude of 7.9 and a maximum Mercalli intensity of XI (Extreme).

The 2014 Murmuri earthquake occurred on August 18 in the Zagros Mountains of Iran with a moment magnitude of 6.2 and a maximum Mercalli intensity of VIII (Severe). The dip-slip shock injured 60–330 people and was followed by a number of high intensity aftershocks.
The 2010 Damghan earthquake occurred in northern Iran at 11:53:49 local time on August 27 with a moment magnitude of 5.8 and a maximum Mercalli intensity of VII. This strike-slip event damaged and destroyed a number of small villages in a sparsely populated region near the Alborz mountain range. It left four people dead, forty injured, and about 800 people without homes. The deaths and injuries in this moderate event were attributed to the low quality construction styles that are typical of the area. The Iranian Strong Motion Network provided data by which seismologists determined the type and extent of the slip as well as the peak ground acceleration. Other large and destructive earthquakes have affected the Semnan Province, including several events in 856 AD and 1953.
