THE asteroid strike that worn out the dinosaurs triggered waves 30,000 instances extra highly effective than the 2004 Indian Ocean tsunami, researchers say.
Swells as much as a mile excessive swept the planet, drowning the whole lot.

Scientists scoured hundreds of miles of seabed for proof of disturbed and eroded sediments.
They usually got here up with their idea based mostly on what they discovered at greater than 100 websites worldwide and pc simulations.
An eight-mile large asteroid hit the Gulf of Mexico at 27,000mph 66 million years in the past.
Its preliminary power was as much as 30,000 instances higher than the Boxing Day 2004 tsunami, which killed greater than 230,000.
Molly Vary, of the College of Michigan, US, stated: “This tsunami was robust sufficient to disturb and erode sediments in ocean basins midway across the globe, leaving both a niche within the sedimentary data or a jumble of older sediments.
“Relying on the geometries of the coast and the advancing waves, most coastal areas could be inundated and eroded to some extent.
“Any traditionally documented tsunamis pale as compared with such world impression.”
