Earth’s outer core is an ocean of liquid metal whose volume roughly equals that of Mars. Seismic waves from repeated French nuclear tests at Mururoa have now revealed parts of it changing over only a few years: signals arrived up to 0.2 seconds early or late, suggesting that structures hundreds of kilometres wide are moving through the molten core on human timescales.
38+ min ago (844+ words) Closely matched seismic paths from Mururoa tests changed by up to 0.2 seconds between 1977 and 1995, revealing rapid outer-core variation while leaving the responsible material open to interpretation....
