Bangka Strait, Indonesia
Bangka Strait separates the Indonesian islands of Bangka and Sumatra. The strait was formed 10,000 years ago when global sea levels rose.
Although they are part of the same continental landmass, Bangka and Sumatra don’t share the same geology; while Sumatra is mostly volcanic in origin, Bangka is not.
Bangka Island produces 90% of all Indonesia’s tin, while the country is the world’s second-largest tin exporting nation after China.
Today, tin is used as solder for circuit boards, transistors and resistors in consumer electronics such as smartphones, tablets and laptops.
For more than 2,000 years, the Bangka Strait has been part of an important shipping route that connected Java with Sumatra and Malaysia.
A Dutch treasure ship is thought to lie beneath the waves of the Bangka Strait, thought to be carrying a vast cargo of silver coins and ingots.
