generated by earthquakes on one side of the globe, arrive at different times at a point on the other side of the globe, depending on their route through Earth's inner core. When the path has a component parallel to Earth's rotational axis, the sound waves move faster than when their path takes them along an...
Although scientists can't predict earthquakes, they can predict earthquake shaking a tiny bit in advance for people living near the quake epicenter (the place where the earthquake starts). Earthquake waves take time to travel, so in places with lots of monitoring stations, like Japan, an automat...
Examines why compressional sound waves travel faster along the earth's axis in the inner core. Analysis of the origin of the seismic anisotropy observed in the inner core; Collaboration among several scientists to come up with a method of calculating the elasticity of iron in the inner core; ...
