Asteroids Dinosaur-killing asteroid caused molten rock to burst from ocean floor – study Scientists believe asteroid set off chain of cataclysmic eruptionsViolent eruptions occurred on floor of Pacific and Indian oceans The asteroid was large enough to kill off three-quarters of the life on earth. About 66 million years ago, a six-mile wide asteroid smacked into earth, creating the Chicxulub crater in the Yucatan and sparking deadly chaos. New evidence suggests the shaking triggered massive volcanic eruptions that spewed gases and particles into the air and water. “We’re painting a new sequence of events.”These underwater volcanic areas – called mid-ocean ridges – often erupt, even today. A study in 2015 suggested the collision made volcanic eruptions in India far more intense and deadly.
