If the gas belching dinosaurs don’t get you, the volcanos will.
To: wolfcreek
Looking back there is one 130 million year period where no extinctions occured.
Some scientists contend that a supervolcano was about to explode, but it was plugged up just in the nick of time by an incoming asteroid.
To: wolfcreek
It’s been proposed that big impacts cause volcanism on the OPPOSITE side of the earth through focusing of seismic energy there.
Very controversial though.

I think there was a recent topic about this.
Thanks! .. which is why I stuck it in chat and not

Well the Earth isn’t solid. If you look at it as a ball full of liquid that you shoot with a bullet, the reaction might occur anywhere on it’s surface due to it’s irregularity.

This has been proved now - they found the giant impact crater under Antarctica (off the coast) almost exactly opposite of where the massive Russia crust collapse/volcanic disaster would have been when it hit.

How about astroid strikes that caused massive volcanic activity? I was thinking the same thing. You would think that a sufficiently massive strike would cause shock waves through the mantle that would trigger earthquakes and eruptions
To: wolfcreek
How about astroid strikes that caused massive volcanic activity? The timing isn't all that clear (yet) but I wouldn't be a bit surprised to find that an impact large enough to ring the planet like a bell could trigger massive vulcanism.
I suspect magma may be somewhat thixotropic and flow to the surface much more easily under immediate post impact conditions.
I also think an impact would jar out dissolved gases and 'pump' magma towards the surface. Compare to what you see in a sealed soda bottle when you smack it one!

Worse possible scenario. Shallow water impact. Not only all the crustal damage of a dry land strike, but the instant release of massive amounts of carbon dioxide from a mile thick layer of near shore carbonates laid down as the shells of sea life. Not only the crustal damage, and CO
2 release, but a huge tsunami wiping out shoreline life for thousands of miles. Not just the crustal damage, CO
2 release, and tsunamis, but a global rain of red hot ejecta.
Then there's the really bad part.
The ocean rushes in and tries to fill a 100 km wide white hot crater.
Now instead of passively radiating the excess heat out into space like a dry land strike would, the crater flashes untold cubic kilometers of salt water into steam. Not only does this pretty much steam clean the entire earth's surface, it also rains salt out onto everything, so most plants can't grow even if their seeds managed to survive all the above excitement.

Whew. I just returned from another harrowing trip in the Time Machine. The K-T era website Pre-Republic has a similar story, and it is in Breaking News. Amazing.

Yes indeed, Ban volcanoes
And prosecute all those would seek them out or speak of them.
For the children, the children.

Ill just have the rutabaga Maybe Suunk'll bring a fish to the beach party.
One cleaned gooey duck, stuffed with a topless, skinless rutabaga, and that stuffed into a large turbot, we could have a tubrutaduck.
