"Following the pattern, we're way overdue for a LARGE strike of some kind."

It was just last year that one 'zipped' past only 27,000 miles from earth. It was detected as it was speeding away from earth.

If it were 100 megatons it would have leveled the forest of Germany all the way to Rome. The fireball alone would be 200 miles across.

I think you are confusing the size with the energy/explosive force.

The most likely cause was a low-density comet, 0.7 miles (1.1 kilometres) wide, that broke up at an altitude of 43 miles and fell in pieces to Earth, the scientists reported in Astronomy Magazine.

They wrote: “The main mass of the projectile struck the ground at 2,200 miles per hour, releasing an amount of energy equivalent to 106 million tons of TNT.”

The bomb that destroyed Hiroshima at the end of the Second World War had an explosive force of just 20,000 tons of TNT.

Wrong, the entire cloud created from a 100 megaton explosion would be about 120km across. 200 mile fireball ?? No way, but the thermal pulse might be felt that far.

It is telling that media hyperbole has hugely influenced our collective tendencies towards ascribing far more destructive power to the "megaton" than can be reasonably calculated. I see evidence of this all the time.

The explosion they describe is in the kiloton range. To get megatons the main body would have to strike the ground in the 60,000 miles per hour range, not 2,000.

Several sources suggest you're wrong. Notice in the chart below a 1km diameter meteor is given a 75,000 Megaton kinetic equivalency.

An impact by a 2km diameter stony asteroid is thought to be at the threshold of a global catastrophe and the  "damage" would go well beyond the area of direct devastation. It has been estimated that one quarter of the world's population could die from starvation and other indirect effects due to such an impact, which is thought to have an average interval of 1 million years (Morrison and Chapman 1995).

That is why their description of the damage versus the size of the impactor are so wildly out of whack. Their numbers don't jibe.

Note: this topic is from October of 2004. It antedates the Catastrophism ping list, it was pinged in GGG though. Thanks freedom44.

A blast from the past regarding a blast from the past. Sorry, I couldn’t resist.
