SMOD at last?

(probably not, but one can dream)

I didn't hear the explosion, but here's a little more detail:

Don't worry, I have heard there are plenty of big rocks left over in some of the meteor showers streams that we pass through every year.

IIRC, the biggest one was the Chesapeake Bay impact.  I've always suspected there was a bigger one that formed the semicircular land pattern of the Aleutian Islands.

I've wondered on occasion about the semicircular coast patterns around Myrtle Beach, SC.

[230RN]

Yes, there's a pretty long graceful curve there. Doesn't seem to "match up" with the corresponding coastllne of Europe.  Impactor for that supposed one looks to be about 60 miles east and a wee bit south of Georgetown, kerplunk.

From this map of strikes, it looks possible:



Some are discovered by oil drilling when the characteristic shocked quartz is brought up by the drill. Chicxulub and Chesapeake were found that way.

If you do find a bona fide verified crater, don't expect it to be named after you.  Unlike most discoveries which are named after their discoverers, they are named for nearby communities,

Why does that map not list the Yucatan impact site (Chicxulub)?

[AZRedhawk44]

Seems that living in the southern hemisphere is safer for meteor impacts.  Both from the impact itself as well as the coriolis shield at the equator stopping most weather from crossing south.

Far less detailed geo exploration and drilling in these areas so they're probably there we just haven't found them yet. One of the reasons NA shows so many is that we've been going over NA inch by inch

or the Manson impact

nor Decorah

[230RN]

Yes, I noticed that, too.  I just plucked the image off an image search.  The "problem" is that the time period wasn't specified and I didn't feel like pursuing it down to the actual site. There are a lot of bolide maps that show just one thing or a limited time period.  I was just interested in the eastern coast strikes in re the "Myrtle Beach Curvature" comment.

As an example, looking at this "meteor map," you wouldn't realize it was just for bolides that didn't make contact, without the caption.

Earth would look like the Moon if we didn't have life, weather, tides and tectonic movement to slowly erase the visible signs of impacts.

Probably even worse being a bigger body.

And a lot more of the southern hemisphere is underwater.

[230RN]

Yeah, craters don't last long in water.

Yeah, craters don't last long in water.

And, we mostly don't know what's down there.

Not just those but the atmosphere prevents many impacts by incinerating the smaller ones.  Or they blow up like in that bolide map.

NASA has quelled concerns that a lost 54-million-ton asteroid could potentially hit Earth this year, devastating large regions of the planet.

GB News reported at the time that there was a roughly 1 in 10 million chance of the asteroid slamming into Earth by March 3, 2030 or a 1 in 11.5 million chance of striking the Earth on October 5, 2024.
NASA told The Standard: "There are no known asteroid impact threats to Earth at any time in the next century. NASA and its partners diligently watch the skies to find, track, and categorize asteroids and near-Earth objects (NEOs), including those that come close to Earth."

Party pooper
But a 1 in 10 million chance is better odds than the lottery so there's still hope.

Let's get this done.

Interestingly, the "Story Channel" is running a survey of doomsday predictions over the millennia/cultures --including a reversal of the Earth's rotation due to a "SMOD," massive disruption of the sun's activity, et cetera.

Incidentally, I don't see many water impacts generating ocean floor craters.  Depends on speed and depth, but water can figuratively be as hard as concrete at high velocity impacts.
