The Sunda Strait (Indonesian: Selat Sunda) is the strait between the Indonesian islands of Java and Sumatra. It connects the Java Sea to the Indian Ocean. The name comes from the Indonesian term Pasundan, meaning "West Java". It also comes from the name of the Sundanese people, the native people of West Java, with the Javanese people being found mostly in Central and East Java.[1]


The strait stretches in a roughly north-east/south-west orientation, with a minimum width of 24 km (15 mi) at its north-eastern end between Cape Tua on Sumatra and Cape Pujat on Java. It is very deep at its western end but as it narrows to the east it becomes much shallower, with a depth of only 20 m (65 feet) in parts of the eastern end. This makes it notoriously difficult to navigate, with sandbanks, very strong tidal flows and man-made obstructions such as oil platforms off the Java coast. It had been an important shipping route for centuries, especially during the period when the Dutch East India Company used it as the gateway to the Spice Islands of Indonesia (1602-1799). However, the strait's narrowness, shallowness, and lack of accurate charting makes it unsuitable for many modern large ships, most of which use the Strait of Malacca instead.[2]

The strait is dotted by a number of strait islands, including Sangiang (Thwart-the-Way), Sebesi, Sebuku, Panaitan (Prince's) and most notably, the Krakatau Islands: Lang (Panjang or Rakata Kecil), Verlaten (Sertung), Krakatau, and Anak Krakatoa. Many of these (including Sebesi and Panaitan) are volcanic in origin, but the best known volcano is Krakatau. The islands in the strait and the nearby surrounding regions of Java and Sumatra were devastated by the eruption of Krakatau in 1883, primarily due to intense pumice fall and huge tsunamis caused by the collapse of the volcano. The eruption drastically altered the topography of the strait, with as much as 18–21 km³ of ignimbrite being deposited over an area of 1.1 million km² around the volcano. Some areas have never been resettled (such as the coastal region of Java now incorporated into the Ujung Kulon National Park), but much of the coastline is now very densely populated.

The Battle of Sunda Strait

On March 1, 1942, the Battle of Sunda Strait—part of the larger Battle of the Java Sea—took place when the Allied cruisers HMAS Perth and USS Houston encountered a Japanese amphibious landing force near Bantam commanded by Rear Admiral Kenzaburo Hara,[3] which included a light cruiser and eleven destroyers, four heavy cruisers and a light aircraft carrier.[4] The two Allied cruisers were sunk, while a Japanese minesweeper and a transport vessel were sunk by friendly fire.[2]

Planned bridge

Main article: Sunda Strait Bridge

In the 1960s proposals were made for a bridge across the Sunda Strait and in the 1990s further suggestions arose. A new plan was announced in October 2007 which would entail utilising the islands of Ular, Sangiang and Prajurit to create a four-part suspension bridge reaching 70 metres (230 ft) above sea level with a maximum span of 3 kilometers, nearly 50% longer than the current record holder, the Akashi Kaikyo Bridge. Construction was projected beginning in 2014 if funding, estimated to be at least US$10 billion, could be secured.[5]

An accord was signed in April 2012 with China Railway Construction Corporation for a $11bn road and double track rail bridge.[6] However, in November 2014, the incoming Joko Widodo government announced that plans to build the bridge would be shelved.[7]
