A fierce storm struck both the Black Sea and the Sea of Azov on November 11, 2007. According to news reports, as many as 10 ships either sank or ran aground, one of them an oil tanker. The Russian tanker Volganeft-139 was anchored to the sea floor in the Kerch Strait linking the Black and Azov Seas when 108-kilometer- (67-mile-) per-hour winds tore the ship apart.
