Cephalonia, Greece Overview
The size of the island is about 781 km2 (300 mi2), and the present population density is 55 people per km2 (140/mi2). The town of Argostoli has one-third of the island’s inhabitants. Lixouri is the second major settlement, and the two towns together account for almost two-thirds of the prefecture’s population.
Cephalonia is in the heart of an earthquake zone, and dozens of minor or unrecorded tremors occur each year. In 1953, a massive earthquake almost destroyed all settlement on the island, leaving only Fiscardo in the north untouched.
Among important natural features are the Melissani Lake, the Drogarati caves, and the Koutavos Lagoon in Argostoli.
The island has a rich biodiversity, with a substantial number of endemic and rare species. Parts of it have been declared a site in the European Union’s Natura 2000 network.
