Lakes Between Rome and Apennine Mountains, Italy

February 8th, 2012 Category: Lakes, Mountains

Italy - December 31st, 2011

This image focuses on central Italy, from the Adriatic (above) to the Tyrrhenian (below) Seas. The Adriatic Coast is lined by sediments, while the Tyrrhenian coastline is mostly sediment free. The ridges of the Apennine Mountains can be seen running down the middle of the Italian peninsula, part of which are capped by snow.

The city of Rome can be seen in the full image, appearing as a grey area near the coast in the bottom half of the image. Visible to the west and northwest of the city are three large lakes: Lake Bracciano (dark blue, closest to Rome), Lake Bolsena (dark blue, northwest of the former) and Lake Trasimeno (light blue, located near the center of the width of the peninsula).

Wave Clouds Over Apennine Mountains, Italy

Italy - December 26th, 2011

Sediments line the Adriatic coast of Italy (right) while the western coast is mostly clear. Several rounded crater lakes are visible near the west coast in the central part of the country, the largest of which is Lake Bolsena, formed starting 370,000 years ago following the collapse of a caldera of the Vulsini volcanic complex into a deep aquifer.

Visible northeast of the lake are wave clouds, formed by atmospheric internal waves that are created as stable air flows over a raised land feature such as a mountain range, and can form either directly above or in the lee of the feature. Here, the wave clouds have formed over the Apennine Mountains.

Italy - August 27th, 2010

This thumbnail image focuses on central Italy, from the Adriatic (above) to the Tyrrhenian (below) Seas. The ridges of the Apennine Mountains can be seen running down the middle of the peninsula, dark green in color.

In the full image, most of the Italian Peninsula, as well as the nearby islands of Corsica (France), and Sardinia and Sicily (Italy), can be seen.

In the thumbnail, several lakes can be observed, northwest of Rome, which appears as a grey area by the Tyrhennian shores of the peninsula. The lakes are Lake Bracciano (closest to Rome), Lake Bolsena (northwest of the former) and Lake Trasimeno (green, further inland).

Italy - April 28th, 2010

The city of Rome appears as a tan area spreading inland from the coast in the lower right corner. Visible to the left are three large lakes: Lake Bracciano, Lake Bolsena and Lake Trasimeno (light blue).

The closest to Rome is Lake Bracciano, circular and dark blue in color. It lies in the Sabatini Mountains, just northwest of the city, and is drained by the Arrone River on its southeast side. Mineral hot springs along its shores recall its earlier geologic formation from a group of volcanic craters.

The surface lies 538 feet (164 m) above sea level, with an area of 22 square miles (58 square km). The maximum depth is 525 feet (160 m) and the diameter is about 5.5 miles (9 km).

Italy - January 3rd, 2010

Sediments line the coast of Italy and flow into the Tyrrhenian Sea from rivers including the Tiber, which flows through  the city of Rome before entering the sea, and the Ombrone, which flows past the city of Grosseto. The mouth of the Tiber is visible releasing dark brown sediments in the lower right quadrant, while that of the Ombrone releases thick tan sediments near the left edge.

Three large lakes can also be seen (from top to bottom): Lake Trasimeno, which appears light blue near the upper edge, as well as Lake Bolsena and Lake Bracciano, both darker blue and closer to the center of the image. Appear 20 kilometers northwest of Lake Bolsena, in the southern Tuscany region, is Monte Amiata. It is the largest of the lava domes in the Amiata lava dome complex.
