Editing Tyrrhenian Sea (section)

==Geography==
The sea is bounded by the islands of [[Corsica]] and [[Sardinia]] (to the west), the [[Italian Peninsula]] (regions of [[Tuscany]], [[Lazio]], [[Campania]], [[Basilicata]], and [[Calabria]]) to the north and east, and the island of [[Sicily]] (to the south).<ref>{{cite encyclopedia |url=https://www.britannica.com/place/Tyrrhenian-Sea |title=Tyrrhenian Sea |encyclopedia=[[Encyclopedia Britannica]] |access-date=July 18, 2017 |editor-last=Chisholm |editor-first=Hugh |editor-link=Hugh Chisholm |publisher=[[Cambridge University Press]] |author=((The Editors of Encyclopaedia Britannica))}}</ref> The Tyrrhenian Sea also includes a number of smaller islands like [[Capri]], [[Elba]], [[Ischia]], and [[Ustica]].<ref>{{Cite web |url=http://www.worldatlas.com/aatlas/infopage/tyrrheniansea.htm |title=Tyrrhenian Sea - Map & Details |work=World Atlas |access-date=July 18, 2017}}</ref>

The maximum depth of the sea is {{convert|3785|m|ft}}.

The Tyrrhenian Sea is situated near where the [[African Plate|African]] and [[Eurasian Plate]]s meet; therefore mountain chains and active volcanoes, such as Mount [[Marsili]], are found in its depths. The eight [[Aeolian Islands]] and [[Ustica]] are located in the southern part of the sea, north of [[Sicily]].

===Extent===
The [[International Hydrographic Organization]] defines the limits of the Tyrrhenian Sea as follows:<ref>{{cite book |url=https://iho.int/uploads/user/pubs/standards/s-23/S-23_Ed3_1953_EN.pdf |title=Limits of Oceans and Seas |volume=172 |edition=3rd |year=1953 |work= [[International Hydrographic Organization]] |access-date=May 2, 2020 |page=17 |issue=28|bibcode=1953Natur.172R.484. |doi=10.1038/172484b0 |s2cid=36029611 }}</ref>
* In the [[Strait of Messina]]: A line joining the North extreme of Cape Paci (15°42′E) with the East extreme of the Island of [[Sicily]], Cape Peloro (38°16′N).
* On the Southwest: A line running from Cape Lilibeo (West extreme of Sicily) to the South extreme of Cape Teulada (8°38′E) in [[Sardinia]].
* In the [[Strait of Bonifacio]]: A line joining the West extreme of Cape Testa (41°14′N) in Sardinia with the Southwest extreme of Cape Feno (41°23′N) in Corsica.
* On the North: A line joining [[Cap Corse|Cape Corse]] (Cape Grosso, 9°23′E) in Corsica, with [[Tinetto]] Island ({{coord|44|01|N|9|51|E|display=inline}}) and thence through [[Tino (island)|Tino]] and [[Palmaria (island)|Palmaria]] islands to San Pietro Point ({{coord|44|03|N|9|50|E|display=inline}}) on the coast of Italy.

===Exits===
There are four exits from the Tyrrhenian Sea (north to south):

===Basins===
The [[Tyrrhenian Basin]] is divided into two basins (or plains), the Vavilov plain and the Marsili plain. They are separated by the [[undersea ridge]] known as the Issel Bridge, after [[Arturo Issel]].<ref name=":0">{{cite journal |last=Sartori |first=Renzo |title=The Tyrrhenian back-arc basin and subduction of the Ionian lithosphere |journal=[[Episodes (journal)|Episodes]] |year=2003 |volume=26 |issue=3 |pages=217–221 |url=http://www.episodes.org/backissues/263/10Sartori.pdf |archive-url=https://web.archive.org/web/20081219151730/http://www.episodes.org/backissues/263/10Sartori.pdf |archive-date=December 19, 2008 |publisher=[[University of Bologna]]|doi=10.18814/epiiugs/2003/v26i3/011 |doi-access=free }}</ref>
