"The Fars Earthquake (2010)"

- CONTENT--
The 2010 Fars earthquake is a series of powerful earthquakes of magnitude up to 5.9 that occurred in 2010 in the Iranian region of Fars.

The first of them, a magnitude of 5.9, occurred on September 27, 2010 at 11:22:45 (UTC) in southern Iran, 2.3 km north-north-east of the city of Kazerun (stan Fars). The hypocenter of the earthquake was located at a depth of 20.0 kilometers. The intensity of the earthquake was VII on the Mercalli scale.

The earthquake was felt in Shiraz, Bushehr, as well as in Kuwait: in Salimiya, in the area (Assam governorate), in Mankaf, Hawalli, .

As a result of the earthquake in Konartecht, 1 person died and 3 were injured. A total of 7 people were injured. Economic damage from the earthquake amounted to 3.72 million US dollars.

Repeated earthquakes

On November 26, 2010 at 12:33:42 (UTC) in the Fars region, at a depth of 9.0 km, an earthquake of magnitude 5.5 occurred. The epicenter was located 64.6 km north-north-west of the city of Mohr. Tremors were felt in the settlements of Iran: Kengan, Shiraz. Tremors were also reported from Manama (Bahrain) and Doha (Qatar). There were no reports of casualties. Economic damage from the earthquake amounted to 4.85 million US dollars.

Tectonic conditions of the region
At least four tectonic plates (Arabian, Eurasian, Hindustan and African) and one smaller tectonic block (Anatolian Plate) are responsible for seismicity and tectonics in the Middle East and the surrounding region. The geologic development of the region is a consequence of a number of first-order tectonic processes that include subduction, large-scale transform faults, and the uplift and expansion of the Earth’s crust.

In the east, tectonics is dominated by the collision of the Indian plate with Eurasia, leading to the rise of the mountain ranges of the Himalayas, Karakoram, Pamir and Hindu Kush. Under the Pamirs and the Hindu Kush Mountains in northern Afghanistan, earthquakes occur at depths of up to 200 km as a result of residual lithospheric subduction. Along the western edge of the Indian Plate, the relative movement between India and Eurasia occurs in shifts, scatters, and cross-parallel layers, resulting, for example, in the Suleyman Mountains complex being a fold-over belt. The main fault in this region is in Afghanistan.

Off the southern coasts of Pakistan and Iran, the Makran Trench is a superficial expression of the active subduction of the Arabian Plate under Eurasia. To the northwest of this subduction zone, the collision between the two plates forms folded belts about 1,500 km long and the Zagros Mountains fold-over belt, which cross all of western Iran and spread into northeastern Iraq.

Tectonics in the eastern Mediterranean region is dominated by complex interactions between the plates of Africa, Arabia and Eurasia and the Anatolia block. The dominant structures in this region are: the Red Sea Rift - the center of expansion of the earth's crust between the African and Arabian plates; - a large fault with a displacement along the stretch, in which also
