Where do asteroids impact upon the Earth most often?

Are impact zones primarily along the equator?

Is there an average area where impacts are more likely to occur?

If there is a zone, is there a way to determine if it's changed? More to the point, if there is an impact zone, are there any similar areas that might indicate the zone has shifted?

The occur all over the world. On this image each yellow circle is an recent impact of a small asteroid the size of the circle is related to the energy of the fireball (the sizes of the circles don't represent crater areas). You will note that there is no region that get more impacts, and similarly, nowhere is safe.

The very large yellow circle is the Chelyabinsk meteor in Russia. It was the biggest such impact over land in recent times.

  • $\begingroup$ Thank you! Is there a website you got that image from? I tried searching for information on impacts to no avail and I'm guessing I was searching the wrong keywords $\endgroup$ – Chimera.Zen Jun 4 '18 at 20:20

    $\begingroup$ The information is from the cneos.jpl.nasa.gov/fireballs jpl fireball database. The image I made myself (a couple of years ago) since I wasn't happy with the equirectangular projection that nasa use. $\endgroup$ – James K Jun 4 '18 at 20:31

    $\begingroup$ but for the purpose of illustrating the uniform distribution of impacts, an equal area projection is better. Peters is horrible, hence Molyweide. $\endgroup$ – James K Jun 4 '18 at 22:31

    $\begingroup$ I would have thought that was fairly obvious, unless there are a lot of craters in the sea, and a very large chunk of Russia is missing! $\endgroup$ – James K Jun 4 '18 at 23:19

    $\begingroup$ Nor would that prove the conjecture, at best it would show it is "consistent with a uniform distribution". But I think the map illustrates that there are no "impact zones along the equator quite well. The question was not "is the distribution uniform" but "are there impact zones and do they move" $\endgroup$ – James K Jun 5 '18 at 19:53
