The Tyrrhenian Basin is a sedimentary basin located in the eastern Mediterranean Sea. It covers a 231,000 km² area that is bounded by Sardinia to the west, Corsica to the northwest, Sicily to the southeast, and peninsular Italy to the northeast. The Tyrrhenian basin displays an irregular seafloor marked by several seamounts and two distinct sub-basins - the Vavilov and Marsili basins. The Vavilov deep plain contains the deepest point of the Tyrrhenian basin at approximately 3785 meters. The basin trends roughly northwest-southeast with the spreading axis trending northeast-southwest.
