By combining a phase field function approach with bulk thermodynamics of mineral phases, the thermal history of a rock can now be deciphered from its distribution of mineral phases.

A New Workflow to Image the 3D Structure of Active Faults
A new approach to illuminate 3D fault structures using earthquake hypocenters may improve our understanding of earthquake propagation and arrest across step overs.
Machine Learning Helps Constrain the Thickness of Ancient Crust
A machine learning model trained using data on the chemical composition of magmatic rocks yields comparable, if not better, results to previously developed geochemical proxies.
Zooming in on the Nucleus of Earthquake Fault Slips
Controlled arrest and re-nucleation of laboratory earthquakes reveals nucleation processes unapproachable by traditional linear elastic fracture mechanics.
Bayesian Inversion Used to Recover Geometry of Ruptured Fault
A new Bayesian inversion framework is used to solve non-planar geometry of a ruptured fault from spatially variable slip and rake measured with geodesy.
GPS Observations Sense Groundwater Change in Australia
By exploiting the fact that changes in groundwater cause deformations of the Earth’s surface, GPS receivers are used to detect groundwater changes related to extreme events and to seasonal oscillations.
Radar Satellites Capture Subtle Slip Evolution on Faults
A five-year time series from radar satellite imagery tracks surface slip on major faults in the San Francisco Bay Area, capturing subtle velocity variations and controlling factors.
How Big Data is Helping Environmental and Climate Research
A new special collection invites papers focusing on the processing, modeling, and analysis of all types of big datasets in the Earth and space sciences, including the influence of solar forcing on Earth’s climate.
Rapid Evolution of Volcanic Systems Reflected in Magnetics
Spatiotemporal magnetic monitoring along with InSAR models is a powerful tool to image magmatic, hydrothermal, and mechanical changes within the volcanic edifice of the Piton de la Fournaise.
