the Lake Trasimeno

The Lake Trasimeno.

The lake is originally an alluvial lake, partly tectonic origin ( a part of geology which studies the structur, the deformation, the movements of the earth’s crust ) residue of a vast Pliocene basin ( last period of Neocene, second half of the Tertiary period between the Miocene and the Pleistociene period between 7 and 1,5 to 2 million years ago when an extensive transgression of oceans took place, which flooded practically all Mediterranean regions.
In Italy, emerged only the Alps and the Appennin, last period of the geological periods before men appeared on the globe, era of the great cataclysms of the tertiary period ) which extended from the plain of Valdi Chiana, including lake Chiusi and Montepulciano.

It is besides Lake Garda, Lago Maggiore and Lake Como the biggest lake of the Italian peninsula.

It is 258 mt. Above sea level, has a 54km perimeter and a 128 sq. km area, its approx. depth is 5 meters reaching a maximum of 7 meters between Isola Maggiore and Isola Minore.

Being principally an alluvial lake, it naturally follows that this data is subject to variations due to higher or lower annual rainfalls.
