2012 East Azerbaijan earthquakes

The 2012 East Azerbaijan earthquakes - also known as the Ahar earthquakes - occurred on 11 August 2012, at 16:53 Iran Standard Time, near the cities of Ahar and Varzaqan in Iran's East Azerbaijan Province, approximately 60 kilometers (37 miles) from Tabriz. They comprised a doublet separated by eleven minutes, with magnitudes of 6.4 and 6.2 Mww. At least 306 people died and more than 3,000 others were injured, primarily in the rural and mountainous areas to the northeast of Tabriz (though 45 died in the city of Ahar). The shocks were felt in Armenia and the Republic of Azerbaijan, though no major damage was reported.

Sheremetyevo International Airport opened

Sheremetyevo Alexander S. Pushkin International Airport is one of four international airports that serve the city of Moscow. It is the busiest airport in Russia, as well as the 13th-busiest airport in Europe. Originally built as a military airbase, Sheremetyevo was converted into a civilian airport in 1959. The airport was originally named after a nearby village, and a 2019 contest extended the name to include the name of the Russian poet Alexander Pushkin. The airport comprises six terminals: four international terminals (one under construction), one domestic terminal, and one private aviation terminal. It is located 29 km (18 mi) northwest of central Moscow, between towns of Lobnya and Khimki in Moscow Oblast.
