Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

Earth's inner core may be layered like an onion, with silicon and carbon creating distinct zones that explain seismic wave ...

Scientists used seismic data discovered Earth's inner core displays a variety of textures that it acquired will it formed from within the fluid outer core. The data set was generated over the past 27 ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU). By ...
