The French Navy starting another round of nuclear testing might be more likely for this one, it's only 20 years since their last ones. We should get greenpeace

The French Navy starting another round of nuclear testing might be more likely for this one, it's only 20 years since their last ones. We should get greenpeace to send the Rainbow Warrior III over.

Too easy to detect nuclear testing these days, doubt its that

  Is it? I thought sysmographics were how we knew about North Korean testing. I assume a deep underwater test would be just as hard. But as another more knowledgeable poster mentioned, it doesn't fit the profile.

    There is an extensive monitoring system in place to enforce the CTBT (Comprehensive Nuclear-Test-Ban Treaty). You can find the stations here: https://www.ctbto.org/map/ https://www.ctbto.org/map/ (check 'international monitoring system' on the right side) As you can see, there are seismic station for detecting underground tests (the signal differs from earthquake signals if you look at stations around the world), acoustic and hydroacoustic stations for detecting tests in the atmosphere and oceans, and isotope detection to differentiate between any kind of explosion and a nuclear one (which leave the same signal in the other detectors). The stations have a fantastic global coverage and have been measuring for quite a while. The data set is now also given to the scientific community for all sorts of purposes. https://www.ctbto.org/verification-regime/potential-civil-and-scientific-applications-of-ctbt-verification-data-and-technologies/ https://www.ctbto.org/verification-regime/potential-civil-an... https://en.wikipedia.org/wiki/Preparatory_Commission_for_the_Comprehensive_Nuclear-Test-Ban_Treaty_Organization https://en.wikipedia.org/wiki/Preparatory_Commission_for_the...

Not a nuclear test because there's no initial transient. This is more like a forced resonance - the geological equivalent of an organ pipe. So I'd guess there's a pipe-like feature or a chamber in the area (an old magma tunnel? - it doesn't have to be empty, it just needs to have a constant density significantly different to its surroundings) and "noise" from moving magma made it to ring. With a 17s period and 6km/s velocity, for lambda/4 resonance the pipe/chamber would be around 30km long - which looks not-completely-insanely-wrong, possibly.

  Horn of ancient gods/aliens announcing Apocalypse! Earth just blew a whistle: "Humanity Stahp!" The Trumpet will (just) be sounded, when all that are in the heavens and on earth will swoon, except such as it will please God (to exempt). Then will a second one be sounded, when, behold, they will be standing and looking on! — Sura 39 (Az-Zumar), ayah 68

Lets hope they don't sink it like they did the first one.
