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.
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 by 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.
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. It struck at a depth of 10 kilometres (6.2 mi), near the towns of Khvormuj and Kaki. "Dozens" of aftershocks followed, most within the first hour of the main quake. The strongest aftershock had a magnitude of 5.6.
The area is home to ten thousand people and fifty villages. The United States Geological Survey (USGS) estimated that 80,000 people experienced strong tremors while several million felt light shaking. The earthquake was felt in many countries around the Persian Gulf, including Qatar, Bahrain, Saudi Arabia, and the United Arab Emirates.
