Mount Rinjani and Ripples Between Indonesian Islands – December 16th, 20118.4S 116.4E
This orthorectified wide-swath ASAR image focuses on Bali, an Indonesian island located in the westernmost end of the Lesser Sunda Islands, lying between Java to the west (left edge) and Lombok to the east (right edge).
Of particular note on the islands are many volcanic peaks. One of the most prominent is Mount Rinjani, an active volcano on Lombok. It rises to 3726 m, making it the second highest volcano in Indonesia. On the top of the volcano is a 6 km by 8.5 km caldera, which is filled partially by the crater lake known as Segara Anak (Child of the Sea). This lake is approximately 2000 metres above sea level and estimated at 200 metres deep.
Visible at the top edge in the upper right quadrant is Saubi, one of the islands of the Kangean Archipelago. Administratively, the island is located in East Java, Indonesia. Multiple parallel rows of semicircular ripples can be seen spreading northwards from Bali and Lombok towards Saubi.
