Earth’s Subduction May Have Been Triggered by the Same Event That Formed the Moon

Rachel Fritts, Science Writer by Rachel Fritts 20 May 202420 May 2024

The giant impact that formed the Moon may also have led to extrastrong mantle plumes that enabled the first subduction event, kick-starting Earth’s unique system of sliding plates.

A Strong Pacific Plate Bends Under the Hawaiian Volcanic Chain

by Emilie Hooft 14 March 202413 March 2024

Two seismic studies reveal the volcanic loads and resulting flexure of the Pacific plate at the Hawaiian Ridge and, surprisingly, show no magmatic underplating.
