The wave's round trip to Earth's core set off a fault slip along Japan's plate boundaries, revealing a seismic hazard ...

Shaking from large earthquakes provides hints about something different at the center of the planet. By Kenneth Chang The inner core of the Earth appears to hold an innermost secret. Geology textbooks ...

Scientists have harnessed powerful waves from earthquakes to measure Earth's innermost layer and found that our planet's center is a 450-mile-wide (725 kilometers) ball of solid iron-nickel alloy.

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other shifts at ...

The detection of energy signals from strong winter storms in the North Atlantic Ocean that travel through Earth's core could enhance understanding of our solar system, according to new research from ...
