A new tool to predict volcanic eruptions

The inner core is likely composed of the hexagonal close packed phase of iron and located at the center of the Earth at pressures between 329 and 364 GPa and temperatures of ~5000 to ~6000 K. Credit: Ehime University

Is the Earth’s inner core oscillating and translating anomalously?

The early Earth was hotter than it is today and this affected the strength of the crust and mantle.
