There apparently is a large impact crater on the exact opposite side of the earth from the Siberian Traps. It is called the Falklands Crater, and it is west of the Falklans. See the following Link:

Massive impact crater may be hiding near the Falklands

The Chicxulub Crater that wiped out the non-avian dinosaurs about 65 million years ago is about 110 miles (180 kilometers) wide. The suspected Falklands Crater is estimated to be 155 miles (250 kilometers) wide and may be the second largest impact crater know on earth. The age of the Falklands Crater is estimated to be 250 to 270 million years old (in the ballpark of the mass extinction at the end of the Permian), but the crater has not been drilled into yet to give a better date estimate.

I've often wondered how such large impacts would affect the earth. Would the earth ring like a bell such that something like the Siberian Traps or volcanoes might occur on the opposite side of the earth where large tectonic (?) waves resulting from the impact might converge? The Deccan Traps in India are about the same age as the Chicxulub Crater. They are on the opposite side of the earth from Chicxulub but not the exact opposite location.

I'm no geologist, as you probably can tell. My sister is a PhD geophysicist though. I'll bounce it off of her.

"Just before the extinctions, volcanoes in what is now Siberia erupted on a tremendous scale."

The eruptions lasted 300,000 years before the estimated start date of the extinctions and covered 2.7 million square miles. But the warmists would have us believe that the carbon dioxide released by the eruptions caused surface warming. Never mind thousands of years of massive lava flows.



Note that CO2 level was not as high as it was during the Jurassic, which was known for large healthy dinosaurs.

The warmists have only 1 hammer in their toolbox, "greenhouse gases". Warming must always be explained as due to an increase in such gases.
