The Sea of Galilee is Israel's biggest freshwater lake, about 53 kilometers (33 miles) around, about 21 km (13 miles) long, and 13 km (8 miles) wide; it has a total area of 166 km², and a depth of about 43[1] meters. At 209 meters below sea level, it is the lowest freshwater lake on Earth, and the second lowest lake in the world after the Dead Sea, a saltwater lake. It is not a real sea - it is called a sea because of tradition.
The lake is also known on modern maps as Lake Galilee or Lake Tiberias, in the region of Galilee. In modern Hebrew, it is known as Yam Kinneret (help·info) (ים כנרת), "Sea of Kinnereth" (Numbers 34:11; Joshua 13:27). It has also been called the Lake of Gennesaret or the Sea of Gennesaret (Luke 5:1) after the name of a small fruitful plain on its western side. The Arabic name for the lake is Buhairet Tabariyya (help·info) (بحيرة طبريا) meaning Lake Tiberias. Other names are: Ginnosar, Lake of Gennesar, Sea of Chinneroth, Sea of Tiberias (Roman) and Waters of Gennesareth.
Its main source is the Jordan River, which flows through it from north to south. The lake is deep in the Jordan Great Rift Valley, the valley caused by the separation of the African and Arabian Plates. Because of this, the area has earthquakes and, in the past, volcanic activity.
Because of its low-lying position in the rift valley, surrounded by hills, the sea can get sudden violent storms[source?]; as in the New Testament story about Jesus calming the storm. A main feature of the lake seems to be that it is always changing. It is still famous, just as in New Testament times, for having plenty of fish, and in today's restaurants, "St. Peter's Fish" (tilapia) is very popular.
