Indonesia - November 8th, 2011

This orthorectified wide-swath ASAR image shows Surabaya, located on the northern shore of eastern Java at the mouth of the Mas River and along the edge of the Madura Strait. It is Indonesia’s second-largest city, with a population of over 2.7 million (5.6 million in the metropolitan area), and the capital of the province of East Java.

Visible in the lower half of the image are numerous volcanic peaks, the most prominent of which are Iyang-Argapura (far right) and the Tengger Massif (due south of Surabaya). Iyang-Argapura is a massive volcanic complex that dominates the landscape between Mount Raung and Mount Lamongan in East Java. Valleys up to 1,000 m deep dissect the strongly eroded Iyang volcano.

The Tengger massif, also in East Java, includes Mount Bromo, an active volcano. At 2329 m it is not the highest peak of the massif, but is the most well known due to its activity and the fact that it sits in the middle of a vast plain called the “Sea of Sand”.
