The Indo-Australian Plate is a tectonic plate located beneath the Indian Ocean and parts of Australia. It is a major plate that includes the continent of Australia, the Indian subcontinent, and surrounding oceanic regions. This plate is significant in understanding geological activity, including earthquakes and volcanic eruptions, as it interacts with neighboring plates. The plate is bordered by several other tectonic plates, including the Eurasian Plate to the north and the Pacific Plate to the east. The movement of the Indo-Australian Plate is responsible for the formation of the Himalayas and the geological features of the Australian continent. Its dynamics play a crucial role in shaping the Earth's surface in this region.
