Finland Explosion

[blobrana]

Hum,
The word on the street says that a large (300 meters diameter) impact crater has been found in the Mantokoski river in Utsjoki, northern Finland, approximately one kilometre from the closest settled area.
To create such a crater you need a very big meteorite.
It was estimated that the impact occurred before Christmas.

Anyone know anything about it?

No news of any craters or explosions here, but I see you already found an alternative explanation anyway (on the astronomy message board) :-)

 Hum,
Yeah, 300 metre strewn field is perhaps a more likely explanation...

And at 1 euros per gram there is enough lying around to pay for a package holiday to Finland...

No offence, but isn't 'explosion' a bit of an exaggerative title? :-)

Hum,
From initial reports of a 300-metre crater - it would require the force of a small nuclear bomb (or a large 20-metre rock)

However that possibility seem unlikely now.

The information is still a bit sketchy, but a possibility offered by a few ppl is that it was a large methane bubble that broke through to the surface.

There was a small bit about this in a newspaper today, apparently some experts think there is nothing special about the holes since such openings occur naturally all the time. No mention of methane bubbles in this article but they are at least pretty sure no meteorites have hit the ground lately.

Since I am positive reading Finnish will prove to be no difficulty, here is the original article ;-)

ajk knows the real reason but the black helicopters are circling and he's too scared to say.....

Probably some poor guy got buried under the ice generations ago having had sprouts with his xmas dinner...

Hum,
similar to a monty python sketch.

Several years ago, there is a huge explosion on Mekong River. Apparently during the Vietnam war a huge bomb (from airplane) was buried on the ground. Because of recent flood and mudslides, the bomb was thrown into the river, hit a rock and exploded.

US had lost one of its nuclear bombs on a swamp in Georgia:

"What is not in dispute is that on the night of February 4-5, 1958, a B47 bomber set out from Homestead Air Force Base in Florida with a Mark 15 Mod 0 on board. This was one of America’s earliest thermonuclear bombs, containing 400lb of conventional explosives and uranium. The 7,600lb weapon was designed with a removable nuclear capsule, or plutonium trigger. Off the Savannah River, an intensive search took place using ships with divers and underwater demolition teams. Local newspapers reported that the Air Force was anxious to recover the “portion” of the weapon it had admitted losing, for security reasons and because it was an “expensive part”. But after three square miles had been examined over more than two months, the search was called off and the bomb was officially declared “irretrievably lost”"

Is it possible that the loud explosion in Finland is from old WW II/coldwar bombs or failed/lost USSR missiles?

Hum,
an interesting idea.

It’s an area that got nothing to bomb, but a good area to dump them.

But, i imagine that returning bombers would normally dump un-dropped bombs into the sea, or as soon as they were on the return journey.
