A sesimic image of the whole Earth

  1. Aug 23, 2008 #1
    Has this been done?

    I've seen tomographically derived "velocity models" of the earth before. These can show features, such as anomalously fast slabs under continents (subducting plates) and anomalously slow blobs beneath hot spots (mantle plumes). But has anybody ever imaged the Earth with actual seismic data before?

    I guess what I mean would be something like this: http://images.google.com/imgres?imgurl=http://www.jsg.utexas.edu/images/big/111507/f2.jpg&imgrefurl=http://www.jsg.utexas.edu/images/enlarged/111507/02.html&h=569&w=900&sz=318&hl=en&start=6&um=1&usg=__TO-abdhZOUK2ZRdA0RsbP8jM8Qs=&tbnid=W6BrqNSDItDHWM:&tbnh=92&tbnw=146&prev=/images%3Fq%3Dseismic%2Bdata%26um%3D1%26hl%3Den%26safe%3Doff%26rls%3Dcom.microsoft:*:IE-SearchBox
    But not just of the crust, but the whole Earth!
