    This could open a new frontier on seismic study of the earths interior.

    http://www.bbc.com/news/science-environment-37177575

    From, http://science.sciencemag.org/content/353/6302/919
    Seismic tomography is like an x-ray of Earth's interior, except that it uses
    earthquakes for the illumination. Earthquakes are imperfect illuminators
    because they are clustered on plate boundaries, leaving much of the interior
    in the shadows. Using a seismic array in Japan, Nishida and Takagi detected
    seismic waves that they attribute to a severe and distant North Atlantic
    storm called a "weather bomb" (see the Perspective by Gerstoft and Bromirski).
    The seismic energy traveling from weather bombs through the Earth appears to be
    capable of illuminating the many dark patches of Earth's interior.

    Two hundred stations?

    Yup, 202 stations, Impressive project all in all. I'm curious to see how well the researchers can fine tune the data and add to our understanding of the Earths interior.

    I'm all for adding to our understanding of Earth's interior. Oil, gas and mineral leasing has been a part of our family business for nearly a century of boom and bust. But perhaps equally interesting is the idea that severe ocean storms in one part of the world can cause microseisms to be felt in another part. My question is, could severe ocean storms trigger earthquakes, and is there any sort of statistical correlation?
