Guy killed by meteorite in India?
Would figure, population density being what it is there. But take it with a grain of salt, those weird 3rd world stories are usually lies.

We can say that ~1 of 7 people hit or killed by objects from space would be in India at the time, based on current population stats. Assuming about 15,000 new meteorites on land per year (that are large enough to get attention, should they hit someone) we should expect about three people to get hit each year, assuming that everyone is never under a roof, in a closed vehicle, under a dense tree canopy, etc. The roof in this incident gave partial protection to the victim: http://news.nationalgeographic.com/n...nce-space-hit/ |

It does combine a fair amount of area with that density though. Irrelevant. The chance that any particular person would be hit is constant, AEBE.

Assuming about 15,000 new meteorites on land per year (that are large enough to get attention, should they hit someone) we should expect about three people to get hit each year, assuming that everyone is never under a roof, in a closed vehicle, under a dense tree canopy, etc. That number seems a bit high for things that reach the ground. You'll have to present your numbers then. |

I know there is a heck of a lot of magnetic dust but anything capable of doing actual damage landing in an inhabited area tends to make the news. The surprising thing about this report is that there are no images of the smoke trail hanging in the sky afterwards or of sonic booms. The roof in this incident gave partial protection to the victim: http://news.nationalgeographic.com/n...nce-space-hit/ The terminal velocity of smaller meteorites and fragments thereof tends to limit their capacity to cause injury. Damage by meteorite was excluded on Japanese insurance policies when we lived there and there was a significant hit leading to children picking up valuable bits of meteorite off the roads and fields. Nice catalogue of the most interesting meteorites witnessed and collected is at: http://www.icq.eps.harvard.edu/meteorites.html France has clocked 60 noticed ones in the past 400 years - most recently: http://www.telegraph.co.uk/news/scie...mily-home.html There were probably lots of other fragments landed but this one got noticed. Chondrites tend to break up in the atmosphere but denser nickel-iron ones arrive in larger lumps and pack a much bigger punch. http://www.thehindu.com/news/nationa...cle8207711.ece |

In fact, nothing about the story is consistent with a meteorite impact. It was almost certainly some kind of ground-based explosion- old ordinance, a bomb, explosive chemicals, etc. |

You'll have to present your numbers then. The entire global catalogue of distinct known confirmed meteorite finds is only about 22000 in all of history up to 2000. http://www.nhm.ac.uk/our-science/data/metcat/ Current running totals are about 20000 in Antarctica, and USA and Libya tied at 1300 each then a long tail of smaller values. http://www.nhm.ac.uk/our-science/dat...erCountry.dsml Modern satellite monitoring gives a much higher estimate in line with your number. Meteorite flux estimates for global hit rate and mass 10g is about 42000 according to Zolensky et Al p875 http://www.lpi.usra.edu/books/MESSII/9021.pdf So about 13k will hit ground rather than ocean but only the ones with masses 100g really stand out well enough to be recognised for what they are and the rest just vanish into the earth. -- Regards, Martin Brown |

But reading a story about it, I find that no traces of explosives were found at the scene, so it's a mystery at this point - the meteorite obviously couldn't have done this by itself. John Savard |

John Savard Denmark has just had a meteorite incident. It caused impact damage to concrete paving slabs in a builder's yard with the fallen material donated to science. A woman used a magnet to collect more material from her back garden. Numerous security cameras recorded a bright fireball lighting up the sky. No recorded deaths or injuries. |
