So Quite, You Can Hear a Snowflake Drop

Looking for the quietest place on Earth? It's at the South Pole - at least from a seismographical perspective. Researchers have operated seismic instruments there since 1957, but, as with urban sprawl in warmer climes, the noise level has grown worse with the population of that area because of new researchers moving in. No worries (a little Dundee lingo there), new locations have been established in 300 meter deep bore holes about 8 km from the old site. Sensitivity is 100 times that of the previous detectors, and 4 times that of anywhere else on Earth. So, when the San Andres Fault finally starts letting go, they'll be the first to know about it.

A huge collection of my 'Factoids' can be accessed from my 'Kirt's Cogitations' table of contents.

Topical Smorgasbord, another manifestation of Factoids, are be found on these pages:
