That was not an earthquake... [Sep. 8th, 2005|03:43 pm]
Strange-quark nuggets impacting the earth!

Just to show that reality is, in fact, deeply weird on a regular basis.

Indeed. I want to get the movie rights to "Strange Impact".

One thing worries me though, in all seriousness:

He added, however, that finding more would be difficult, as seismic databases now automatically remove all signals not linked to earthquakes. He said: "To find more events we need to get at the data before that happens."

This was one of the ways scientists were verifying nuclear test-ban treaties- browsing the public databases for seismic data which wasn't earthquakes and therefore could be underground nuclear tests.

I'm hoping the article was slightly incorrect, that they only remove signals that look like spurious noise, not all non-earthquake signals.

Oh, I'm sure that the uncleaned data exists -- it's just a lot more inconvenient to get hold of than the nice catalogs that have been automatically cleaned and analyzed.

Satisfying my curiosity by looking at my old employers in Geology at Cornell, I'm amused that their Comprehensive Test Ban Treaty monitoring project on which I did summer programming work in the mid 90's, has turned out to be only a fizzled pilot project, since their data only seems to go up to the late 90's. Ah well, it's not like the US takes the CTBT seriously anyway now, either.
