Transient variation in seismic wave speed points to fast fluid movement in the Earth's outer core
Differences in travel time between seismic waves generated by two large earthquakes about 20 years apart suggest a localized density change of 2-3% in the Earth’s outer core during this time which could be caused by fast-moving flows rich in light elements
