Where is the world’s largest known volcanic plateau?

The Deccan Traps are a huge volcanic province in India, formed by massive lava flows around 66 million years ago. They cover much of the Deccan Plateau in western and central India and are among the largest flood basalt regions on Earth. The eruptions occurred near the end of the Cretaceous Period and are often discussed in connection with major environmental changes of that era. The landscape remains an important subject in geology and Earth history.
