Not sure about the celebration though

The explosion had the force of a very lage nuclear bomb, but do we know if it such an incident would cause an EMP pulse?

-Blast

IIRC, the area where the blast was centered was pretty swampy. Any fragments from a metorite probably sank to the bottom of the bog.

We might also want to check if Blast had any ancestors living in the area back then...

The scanned the entire area with what ammounts to giant metal detectors and didn't find anything. This ruled out your normal meteorite/asteroid type objects.

My ancestors were already in the USA by then but I'm trying to get sent to an oil field in Siberia next summer. Maybe I'll be able to check things out.

-Blast

What if it had happened in 1957?

But it didn't, it happened in 1908. That's why celebrate an unusual phenomena of nature.

Think of it this why- you celebrate you kid's birthday, but if you had him when you were 13 (does happen) it might be more of a memorial.

Or maybe we're both failing at this talking/typing thing. :P

Not very big. 20kt is in that funny "operational" range where it is too big be a tacnuke, and realistically too small be to really be a strategic yield by today's standards. It's a nice city buster, but not "big". "Big" means "mega".

As far as an EMP.... helluva good question. Nuclear physics and atomic chemistry both baffle me a bit outside of how to make the things that go boom, so I don't even follow the math that suggests a non-nuclear explosion of that magnitude would result in a release of alpha and/or beta particles. I just know that there is a theory that suggests it. I'd doubt it though.

Actually it was the Borg. Having gone back in time to conquer Earth, while we are weak and easy, the Borg ship had a magnetic constrictor failure that safeguards the gonculator and prevents the discombobulators from allowing the matter/anti-matter mix chamber to fail, thus resulting in a small anti-matter explosion that destroyed all evidence of the Borg and their ship.

You didn't hear the real explanation from me because only the President and myself know that I am here!!! Shshshshsh

Good overview, but I'm questioning of the 10-15 megaton estimate, that's a lot higher than any of the other's I've come across.

*grins* Something to research! I was looking forward to being bored in a few weeks when my current project should be wrapping up. Yay!

To the best of my memory, it was in the 10-15 KT range. About the same size of what we dropped on Hiroshima in 1945.
