Terri Cook

Terri Cook is an award-winning freelance writer whose career has focused on exploring and explaining the 4.5-billion-year-history of the remarkable planet we live on. Cook, who has an M.S. degree in Earth science from the University of California, Santa Cruz, writes about geology, ecology, and the environment—as well as wine, tea, hiking, and biking—for a diverse group of publications, including Eos, Scientific American, NOVA Next, Science News, and EARTH magazine, as well as Avalon Travel and numerous other travel-related publications. Her reporting has taken her to 25 states and 20 countries scattered across 5 continents, from the depths of the Grand Canyon to the sandy Australian Outback to the mist-shrouded summit of Bali’s Mount Batur. As the coauthor of three popular guidebooks, including Hiking the Grand Canyon’s Geology and Geology Underfoot Along Colorado’s Front Range, Cook gives frequent presentations about geology and science communication. She is the recipient of a 2016 European Geosciences Union Science Journalism Fellowship and is based in beautiful Boulder, Colo.

New measurements help researchers assess methane emitted by wetlands

What’s the Average Methane Isotope Signature in Arctic Wetlands?

by Terri Cook 4 May 20173 March 2023

Aircraft measurements confirm that methane emissions from northern European wetlands exhibit a uniform regional carbon isotopic signature, despite considerable ground-level heterogeneity.

Researchers examine the mechanics behind a deadly rock avalanche in China.

What Causes Rock Avalanches?

by Terri Cook 24 April 201710 March 2023

Experimental studies of frictional weakening beneath a deadly rock avalanche in China help to clarify the mechanisms that cause these devastating natural disasters.

A new numerical model tracks the speed and pathway of a dike propagating through the Earth’s crust.

An Improved Model of How Magma Moves Through the Crust

by Terri Cook 18 April 201717 November 2022

Researchers have developed a new numerical model that can, for the first time, solve for both the speed and the path of a propagating dike.

Researchers look at offshore sediments to trace the history of the world’s tallest coastal mountain range

A Mountain Range's History Preserved in Ocean Sediments

by Terri Cook 7 April 201729 June 2022

Fission track dating core samples from the Gulf of Alaska demonstrates that offshore sediments can be used to reconstruct a mountain range's changing exhumation patterns.

Stream Network Geometry Correlates with Climate

by Terri Cook 6 April 20176 June 2022

A "big data" analysis of nearly 1 million river junctions in the contiguous United States shows that branching angles in dendritic drainages vary systematically between humid and arid regions.

Why Do Great Earthquakes Follow Each Other at Subduction Zones?

by Terri Cook 31 March 201716 March 2022

A decade of continuous GPS measurements in South America indicates that enhanced strain accumulation following a great earthquake can initiate failure along adjacent fault segments.

Researchers use samples from Mt. St. Helens to test paleomagnetic methods.

Explaining Why Some Paleomagnetic Results Fail

by Terri Cook 22 March 201727 January 2023

Reordering of mineral crystal lattice structures during laboratory heating may explain the frequent need to reject results of experiments that estimate the intensity of Earth's past magnetic fields.

Cracking of a fluid barrier beneath Japan’s Mount Ontake may have caused the deadly eruption in 2014

What Caused the Fatal 2014 Eruption of Japan's Mount Ontake?

by Terri Cook 17 March 20176 December 2021

Analysis of the change in the stratovolcano's tilt just prior to the explosion suggests that the cracking of a previously intact fluid barrier caused the country's deadliest eruption since 1926.

Researchers trace the history of California’s Whipple Mountains and find a new relationship between normal and detachment faults.
Posted inResearch Spotlights

On the Origin of Low-Angle Detachment Faults

by Terri Cook 7 March 20176 October 2021

Data from California's Whipple Mountains suggest this complex was formed by a succession of steep normal faults, challenging the paradigm that detachments are different types of faults.

Researchers examine New Zealand’s Alpine Fault as it nears the end of its seismic cycle.

Alteration Along the Alpine Fault Helps Build Seismic Strain

by Terri Cook 7 March 201724 March 2023

Detailed analysis of cores drilled through New Zealand's most dangerous on-land fault indicates that its permeability and strength are altered by mineral precipitation between seismic events.
