The Deccan Traps are a large igneous province located on the Deccan Plateau of west-central India (between 17°–24°N, 73°–74°E) and one of the largest volcanic features on Earth. They consist of multiple layers of solidified flood basalt that together are more than 2,000 m (6,562 ft) thick and cover an area of 500,000 km² (193,051 sq mi) and a volume of 512,000 km³ (123,000 cu mi). The term “trap”, used in geology for such rock formations, is derived from the Swedish word for stairs and refers to the steplike hills forming the landscape of the region.
