New Insights from the Magnetic Properties of Fault Rocks
Magnetic studies offer a new strand for the analysis of faulting processes and could help with better understanding of fault rupture and earthquakes.
A Geologist’s Guide to Exploring and Understanding Iceland
A new book explores the geophysical processes that have shaped Iceland over 30 million years and continue to influence the landscape.
Frequency Dependent Plates
Rocks stretch, break, and flow, depending on how and under which conditions they are loaded. A new formulation to better capture Earth’s rheology is explored in the context of plate thickness.
Taking an Aerial View Underground
Wisconsin geologists are testing using drones equipped with thermal cameras to measure shallow soil depths in areas prone to groundwater contamination.
How River Capture Affects the Evolution of Aquatic Organisms
River basins are dynamic environments that are always changing and reorganizing under geologic forces. New research investigates how this shape shifting influences aquatic speciation and extinction.
Exploring by Boring: Geothermal Wells as Research Tools
As part of an effort to develop a geothermal energy source beneath its campus, Cornell University is planning to probe the “boring” old continental crust upon which many people live.
World’s Deepest Freshwater Cave May Be a Kilometer Deep
The Czech Republic’s Hranice Abyss is more than twice as deep as researchers thought.
New Data from Earth’s Largest Non-Volcanic Rift Margin
Seismic reflection images combined with petrological data provide new constraints on the nature of the basement in the enigmatic Australia-Antarctic oceanic-continent transition zone.
J. Casey Moore (1945–2020)
This polymath Earth scientist pioneered multidisciplinary studies of subduction zones on land and at sea.
