The Java Trench is a deep oceanic trench located in the Indian Ocean, near the island of Java in Indonesia. It is part of the larger Sunda Trench system and is formed by the subduction of the Australian Plate beneath the Eurasian Plate. This geological feature is significant for its depth and the unique ecosystems it supports. The trench reaches depths of over 7,000 meters (about 23,000 feet) and is known for its complex geological activity, including earthquakes and volcanic eruptions in the surrounding region. The Java Trench plays a crucial role in understanding plate tectonics and marine biodiversity, making it an important area for scientific research.
