Did dinosaur-killing asteroid trigger largest lava flows on Earth?

30 abril 2015

The theory that an asteroid impact killed off the dinosaurs 66 million years ago is well accepted, but one puzzle is why another global catastrophe — the huge, million-year eruption of the Deccan Traps flood basalts in India — occurred at the same time. Geologists now argue this is not a coincidence. The impact probably rang Earth like a bell, reigniting an underground magma plume and generating the largest lava flows on Earth.
