Amateur geologist makes surprise find

Tokyo - A crater from a meteorite impact more than 20 000 years ago has been discovered in the Japanese Alps, an amateur geologist announced this week. The crater is the first found in this country.
Masao Sakamoto said the crater stretches 900m in diameter and spreads out across rugged, heavily forested land in Nagano state, about 160km west of Tokyo.
Sakamoto, who announced his discovery at an academic symposium earlier this week, said it went largely unnoticed because only about 40 percent of the crater is visible.
"If it had been a clear, pretty circle, it would have been obvious that was a crater," Sakamoto told The Associated Press on Friday. "Everyone around here is really surprised by this."
Sakamoto said analysis of the soil at the site indicates a meteorite about 45m across smashed into the area about 20 000 to 30 000 years ago.
Sakamoto, an elementary school teacher, said he studied the crater - located in the town next to his - for 20 years before he was able to determine it had been formed by a rock from outer space.
At first, Sakamoto thought the mountain ridge and basin might have been formed by a volcano, a fault, or even sculpted out by a glacier. But the soil he found didn't match any of those theories.
After studying craters in the United States and Europe, he discovered some of them had similar features to his ridge - including a mysterious uneven stretch of valleys and hills in middle of the woods.
Quartz found on the site was then proved to have been formed as a result of the intense heat created by the impact of a meteorite, Sakamoto said.
Sakamoto presented his findings at a symposium sponsored by the National Institute of Polar Research, which is involved in geology and geophysics studies. The announcement was front-page news in Japan.
Sakamoto said he hopes the finding of an impact crater in Japan will allow his colleagues easier access to carry out field studies in meteorite research.
"The biggest honor is to have spurred such opportunities in Japan," he said. - Sapa-AP
Let me know if you wish to be added or removed from this ping list.
Huh! So THAT'S how Godzilla got there. It all makes sense now.
The very FIRST thing that popped into the ole noggin was that exact same thought.
You know I was thinking that. The oldest Jomon skeleton found in Japan is only 8,000 years old.
First one ever found in Japan.

No, he came on one of the chariots of the gods.
I heard a piece on NPR a long time ago. A Japanese media concern did a man-in-the-street survey. They asked Americans
to name 3 prominent Japanese.
Godzilla was high on the list of wrong answers. Technically, script-wise, he's French - a product of French nuclear testing in the Pacific.
Yup. I caught that on the initial read of your [as usual, excellent]post.
Maybe it's just me, but the fact that one is found in Japan doesn't come as a major find. No more than if the first one ever was found in Belgium, or Greece, or...[fill in the blank].
Apparently it was copied from a larger American design, but has much better fit and finish.
