Titiwangsa Mountains Along Malay Peninsula

7.0N 99.9E

June 20th, 2012 Category: Mountains

Malay Peninsula - January 6th, 2012

This wide-swath ASAR image shows the Malay Peninsula (or Thai-Malay Peninsula), a peninsula in Southeast Asia (visible in its entirety in the full image). The land mass runs approximately north-south and, at its terminus, is the southern-most point of the Asian mainland. The area contains the southernmost tip of Burma, Peninsular Malaysia, Singapore, and Southern Thailand.

The image shows the ridges and contours of the Titiwangsa Mountains, part of the Tenasserim Hills system, that form the backbone of the Peninsula. They form the southernmost section of the central cordillera which runs from Tibet through the Kra Isthmus (the Peninsula’s narrowest point) into the Malay peninsula.

Jagged Contours of Lake Volta, Ghana

Ghana - January 3rd, 2012

This orthorectified wide-swath ASAR image shows the jagged contours of Lake Volta, the largest reservoir by surface area in the world, and the fourth largest one by water volume. It is located completely within the country of Ghana, and it has a surface area of about 8,502 km² (3,275 square miles). Lake Volta lies along the Greenwich Meridian, and just six degrees of latitude north of the Equator. The lake’s northmost point is close to the town of Yapei, and its southmost extreme is at the Akosombo Dam, 520 kilometers downstream from Yapei. The Akosombo Dam holds back both the White Volta River and the Black Volta River, which formerly converged, where the middle of the reservoir now lies, to form the single Volta River. The present Volta River flows from the outlets of the dam’s powerhouse and spillways to the Atlantic Ocean in southmost Ghana.

Corsica, the Most Mountainous Mediterranean Island

Corsica and Sardinia - January 6th, 2012

This orthorectified wide-swath ASAR image shows the ridges of mountains on the French island of Corsica. Formed through volcanic explosions, it is the most mountainous island in the Mediterranean. Mountains comprise two-thirds of the island, forming a single chain. Monte Cinto is the highest peak at 2,706 metres (8,878 ft) and it has 20 other summits of more than 2,000 metres (6,600 ft). Visible to the south is the Italian island of Sardinia, from which it is separated by the Strait of Bonifacio.

Central Apennine Mountains in Peninsular Italy

42.3N 13.3E

June 17th, 2012 Category: Mountains

Italy - January 6th, 2012

The ridges of mountains running across this orthorectified wide-swath ASAR image belong to the Apennines, a mountain range consisting of parallel smaller chains extending about 1,200 km (750 mi) along the length of peninsular Italy. The Apennine System forms an irregular arc with centers of curvature located in the Tyrrhenian Sea. Here, we focus on that central segment of the range. The center, being thicker and more complex, is geologically divided into an inner and an outer arc with regard to the centers of curvature.

Helsinki and Tallinn by Gulf of Finland and Riga by Gulf of Riga

60.1N 24.9E

Estonia - January 4th, 2012

Visible in the upper part of this wide-swath ASAR image is the Gulf of Finland, the easternmost arm of the Baltic Sea. Visible on opposite sides of the gulf are Helsinki, Finland (northern shores, near the top edge) and Tallinn, Estonia (southern shores, parallel to Helsinki).

Visible to the south of Tallinn is the Gulf of Riga, a bay of the Baltic Sea between Latvia and Estonia. The area of the Gulf of Riga is about 18,000 km². The maximum depth is 67 m. The island of Saaremaa (Estonia) partially separates it from the rest of the Baltic Sea. The city of Riga can be viewed near the gulf’s southern shores.
