Scientists who study earthquakes in Japan said Thursday they have detected a rare deep-Earth tremor for the first time and traced its location to a distant and powerful storm.

The findings, published in the US journal Science, could help experts learn more about the Earth's inner structure and improve detection of earthquakes and oceanic storms.

The storm in the North Atlantic was known as a "weather bomb," a small but potent storm that gains punch as pressure quickly mounts.

Groups of waves sloshed and pounded the ocean floor during the storm, which struck between Greenland and Iceland.

Using seismic equipment on land and on the seafloor that usually detects the Earth's crust crumbling during earthquakes, researchers found something they had not detected beforeā€”a tremor known as an S wave microseism.

The researchers detected the shock waves generated by the North Atlantic storm from Japan, and have used them to gain more detail about Earth's interior.

    i don't know, i don't know ...
    the earth diameter is 12, maybe 13 thousand-something kilometers.
    the "stuff" generally considered responsible for "weather" (which includes storms)
    lives in a thin layer reaching up about 80 maybe 100 kilometers.
    so:
    13'000 km and 100 km
    1'300 and 10
    130 and 1
    13 and 0.1
    so if we shrink the earth to a ball with a diameter of 13 cm then the
    weather "layer" would be ... 1 millimeter.
    i have serious doubts that the gaseous 1 mm layer can affect much, least "make tremors"
    in the solid 13 cm ball, sorry.

    Air is thicker than you think. Can you feel a 10mph wind in your face? You can't see it but you can surely feel it. Try standing up in a 100mph wind, it'll knock you over.

      Numbnuts (GP) thinks that the sun setting or rising is an optical illusion. There's no point trying to help him.

    The schumann resonances are also blamed on the weather, I would consider that the weather is itself an effect and not a cause.

      So you're saying Schumann resonance causes lightning?

        I'd blame the earth's rotation and that star it revolves around, it is called Oracle now.

    Damn. It looks like an Australian Senator [australianpolitics.com] has discovered SN.

    If you ever wondered if it was possible for someone to make Trump look intelligent, I'm ashamed to say a fellow Aussie has managed to do so.
