The Siberian Traps form a large region of volcanic rock, known as a large igneous province, in the Russian region of Siberia.
The large eruptions which formed the traps were one of the largest known volcanic events of the last 500 million years of Earth history. They continued for a million years and spanned the Permian-Triassic boundary, about 251 to 250 million years ago. It was the same time as the Permian–Triassic extinction event, which is estimated to have killed 90% of species existing at the time. The eruption of the Siberian Traps is a possible cause of this "Great Dying".
The term "traps" is derived from the Swedish word for stairs (trappa, or sometimes trapp), referring to the step-like hills forming the landscape of the region, which is typical of flood basalts.
