By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner core has experienced a bit of fluctuations in its movement over time.

Because scientists can't actually see the center of the Earth, they used data from seismic waves created by earthquakes to analyze its composition. "They found the innermost inner core changed the ...

one dataset of seismic waves curiously stood out from the rest," Vidale said. "Later on, I'd realize I was staring at evidence the inner core is not solid." Further, the data showed that the inner ...

Although this inner core is white hot, the pressure is so high ... Instead, scientists map the interior by watching how seismic waves from earthquakes are bent, reflected, sped up, or delayed ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

The way the waves travel reveals what type of material they moved through, including in the inner core, and help to paint a picture of what lies beneath our feet. The new analysis looked at ...

The core itself consists of a solid inner core and a liquid outer core. There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

Earth’s inner core isn’t static. Waves brushing its surface show shifting patterns, suggesting a surprisingly dynamic layer deep below. More observations might uncover hidden processes.
