Subduction Initiation May Depend on a Tectonic Plate’s History

by David Shultz 21 June 202118 January 2022

New seismic imaging study of the Puysegur Trench aims to solve one of the last major questions in plate tectonics.

Magma Pockets Lie Stacked Beneath Juan de Fuca Ridge

Sarah Stanley, Science Writer by Sarah Stanley 14 June 202127 October 2021

Analysis of new imaging data suggests that vertically stacked magma chambers are short-lived and contribute to eruptions.

Raising Central American Orography Improves Climate Simulation

by Sarah Kang 9 June 20218 March 2022

Elevation of Central American orography significantly reduces the pervasive tropical rainfall bias by blocking the easterlies and consequently warming the northeastern tropical Pacific.

Climate Clues from One of the Rainiest Places on Earth

by Andrew J. Wight 7 June 20218 March 2022

One of the world’s rainiest places lies off Colombia’s Pacific coast. New field research sheds light on the Chocó low-level jet, a phenomenon responsible for the region’s precipitation.

Subduction May Recycle Less Water Than Thought

Sarah Stanley, Science Writer by Sarah Stanley 12 February 202127 January 2023

A new analysis of seismic data from the Middle America Trench suggests that previous calculations have vastly overestimated the total amount of water transported to the mantle worldwide.
