The Madura Strait flows between the Indonesian islands of Java (left) and Madura (right). These images were acquired by three different Landsat satellites in 1994, 2000, and 2013.
The city of Surabaya, Indonesia, sits along the strait on the eastern shore of Java. As one of the busiest ports in the country and a main trading location, the city has seen substantial growth along the shoreline. The area has also seen increased boat traffic through the years.
