The 2013 Bushehr earthquake occurred with a moment magnitude of 6.3 on April 9 in Iran. The shock's epicenter was in the province of Bushehr, near the city of Khvormuj and the towns of Kaki and Shonbeh. At least 37 people were killed, mostly from the town of Shonbeh and villages of Shonbeh-Tasuj district, and an estimated 850 people were injured.

Tectonic setting

Iran lies within the complex zone of collision between the Arabian plate and the Eurasian plate. The rate of convergence between the plates near the epicentre is about 30 millimetres (1 in) per year, of which only part is taken up within the Zagros fold and thrust belt. The earthquake was the result of thrust faulting on a NW-SE trending fault plane, consistent with continuing shortening of the Arabian plate. [1]

Earthquake

At 16:22 IRDT (11:52 UTC) on April 9, 2013, an earthquake with a magnitude of 6.3 struck the southwestern coast of Iran, in Bushehr province. [3] [4] It struck at a depth of 10 kilometres (6.2 mi), near the towns of Khvormuj and Kaki. [3] A total of 282 of aftershocks followed, most within the first hour of the main quake. [4] [5] [2] The strongest aftershock had a magnitude of 5.4. [6]

The area is home to ten thousand people and fifty villages. [4] The United States Geological Survey (USGS) estimated that 80,000 people experienced strong tremors while several million felt light shaking. [4] The earthquake was felt in many countries around the Persian Gulf, including Qatar, Bahrain, Saudi Arabia, and the United Arab Emirates. [3] [4] [7]

Damage

At least 37 people were killed and an estimated 850 were injured by the earthquake. [3] Most of those killed were in the town of Shonbeh and villages of Shonbeh-Tasuj District. [3] Of the injured, 100 required hospitalization. [3]

Two villages in the Khvormuj district were reported to have been "levelled". [4] Landslides caused by the earthquake were reported in Kaki City. [8] According to provincial governor Fereydun Hasanvand, 700 homes were damaged, affecting 200 families. [4] Many residents in the Shonbeh District lost power and water services. [5] Residents took to the streets in search of safety as aftershock after aftershock hit. [4] A report by Iran's International Institute of Earthquake Engineering and Seismology stated that most of the buildings damaged were adobe buildings constructed in the last 50 years; and that 100 houses were destroyed, 1,000 people were left homeless, and that about $50 million in damage occurred. [9] In April 10, the largest aftershock with a magnitude of 5.4 injured four people and destroyed buildings already weakened by the mainshock the day prior. [2]

The Bushehr Nuclear Power Plant was not damaged, according to its operator and the governor of the province. [3] It was built to withstand a magnitude 8 earthquake, according to an official. [5]

Aftermath

Iran's Red Crescent Society and the Iranian Navy sent teams to Bushehr Province on the first night to deliver first aid. [3] [9] Several helicopters from nearby provinces helped airlift in emergency supplies. [3] Temporary shelters were erected in the first week after the earthquake. [9]

Three days of national mourning were announced on April 9. [5]

An earthquake occurred on November 27, 2005, at 13:52 IRST on the sparsely populated Qeshm Island off Southern Iran, killing 13 people and devastating 13 villages. It was Iran's second major earthquake of 2005, following the one at Zarand in February. The epicenter was about 1,500 kilometers (930 mi) south of Tehran, close to Iran's southern borders. Initial measurements showed that the earthquake registered about 6.0 on the moment magnitude scale, although that was reduced to 5.8 after further analysis. More than 400 minor aftershocks followed the main quake, 36 of which were greater than magnitude 2.5. The earthquake occurred in a remote area during the middle of the day, limiting the number of fatalities. Iranian relief efforts were effective and largely adequate, leading the country to decline offers of support from other nations and UNICEF.
