The Sunda Strait is a narrow waterway located between the islands of Java and Sumatra in Indonesia. It connects the Java Sea to the Indian Ocean and plays a crucial role in maritime navigation in the region. The strait is approximately 24 kilometers wide at its narrowest point. The Sunda Strait is also known for its geological significance, as it is situated near the Sunda Arc, a volcanic region. This area is home to several active volcanoes, including Krakatoa, which famously erupted in 1883. The strait's waters are rich in marine biodiversity, making it an important area for fishing and tourism.
