Thank you all for the replies! I am glad others have noticed something odd about these numbers as well.

I use this one to check daily, but there are many more accurate sites.
I always asked why 10? Sooooo many at 10? Well perhaps now we have queried, the 'slightly less than 10 figures are cropping up? The 10 and less are soooo disruptive.
I asked the seismological research experts in UK for an answer - and zilch response.
Thank you for your observations - keep at it - check the depths as I think that is a key. 10 was just tooooo frequent until recently when we questionned and now it changes slightly.
Excellent post - and thanks!  |
Avid, I have checked the IRIS website and they actually get their information from USGS, yet each website seems to have earthquakes the other doesn't list, which is a bit strange. How long ago did you ask the folks about the numbers? If there is something wrong here, they would be the ones to know, but could also be under orders to keep their lips sealed. I will also send an email their way asking for an explanation and post it here IF I get one.

Thanks for the article Hippy Chic, interesting indeed! According to the website provided these explosions will allow petroleum to leak out of the earth's crust, so perhaps a pipeline could be installed, for the price of killing off most life in the area.
Certainly, though, this is an interesting thought. Perhaps these recurring numbers which happen on land are bombs being exploded underground?
The USGS website has a separate section for mining blasts, which they say only register on their machines about once every two days, which does not account for the numerous anomalies, even if they somehow register on the main seismic display page. Also, these blasts rarely go deeper than about 1 km.
