New Crater Found Down Under

space.com

SYDNEY, Australia – A new crater, the world’s fourth-largest
at 75 miles (120 kilometers) across, has been found in
western Australia. Scientists believe the impact crater was
caused by a 3-mile (5-kilometer) wide asteroid slamming
into the area, causing a wave of extinction 200 million to
360 million years ago. Upon impact, massive earthquakes
pulsated out hundreds of miles (kilometers) from the site.
Local animal life was vaporized by intense heat or
pulverized by massive sonic waves. The crash also fostered
regional volcanic activity and almost certainly sparked
tsunamis, or tidal waves, in the nearby ocean. Worst of
all, the violent crash must have shot huge amounts of dust
into the sky that blocked out the sun for months, killing
plant and animal life dependent upon stable atmospheric
conditions.
