Russian Meteor released about 33 times the energy of the Hiroshima atomic bomb

www.smh.com.au

A meteor that exploded in the sky above Russia's Ural Mountains was the largest since the Tunguska blast in Siberia in 1908 and released about 33 times the energy of the atomic bomb that destroyed Hiroshima.

Before hitting the Earth's atmosphere on Friday, the object was about 17 metres in size and had a mass of about 10,000 tonnes, NASA said. Russian scientists offered vastly different statistics, saying the meteor weighed about 10 tonnes.

It is interesting to note the meteor was "half the size of a foot ball field" and was reported to weigh 10 tonnes.

I am just glad that it burst out before it landed on soil, we may have had a disastrous event.

Perhaps one might wonder why this just appeared out of the blue without any official reports of this meteor.

A 34 meter football field seems a bit short.

Not really. Small, fast, and coming from the direction of the Sun. Very difficult to see.

Does an energy released about 33 times the energy of the Hiroshima atomic bomb, more interesting than the size, do you think?

It just seems to me there was a lot of energy release, and what difference it made on contact, if it hadn't already burst?

Not sure what you mean by interesting but:

E=0.5*m*v^2

In this case both the m and the v (in particular) were reasonably large.
Energy released is proportional to the square of the velocity. It had a lot of velocity.

That user is in Australia so i believe he is referring to what you know as soccer in America.

Soccer fields are 34 meters long?

I'm from PNG, I had 100m for our average rugby field in mind.

I was rather concerned about the impact if it hadn't burst and contacted the ground? What damage/casualties ensued if had landed in city itself?

It just happened to burst prior to landing. That is like, near death, for those in its vicinity.

It didn't "just happen" to burst.
The physics involved pretty much guaranteed that it would.

So.. basically Russia should be, statically speaking, wreaking in massive deaths & devistation??

No. But a lot of broken glass.
The energy was released 15 miles above the surface.

According to the news report, it had exploded some miles (perhaps 15 miles from Phages), and if the "intensity" of the sonic wave had declined, the effects on contact with nearby infrastructure damage had been reported to be a mere *few* millions US dollars as result.

All in all it seems apparent, despite it's massive energy release, it's real effects on casualties is what matters, statistically speaking.

Since, it barely caused any significant loss of lives, I bet it is a none event then, but was interesting to have known the effects of a meteor of that magnitude and of course the lack of warning from authorities, from what may have been a potential threat for citizens in the vicinity.

You seem to imply that the authorities were lax in some way. Do you think it was known that the meteor was going to arrive?

No and that is my point of it.

All I am saying is that, if it is not picked up by the authorities, for the mere fact of it's size and or the angle to which the next one approaches, you can be rest assured that a warning from the authorities will only come *after* the event as done it's damage.

What other classic example other than that in Russia.
