Challenging the Day Diagram, a Rock Magnetism Paradigm
A critique of the plot routinely used to determine bulk magnetic properties concludes the technique is so ambiguous that new approaches to understanding magnetic mineral assemblages must be developed.

What Shaped the Northern Apennine Deformation Front?
An integrated interpretation of well and seismic reflection data from Italy’s Po Valley shows the range’s undulations are controlled by the slope and composition of two major gliding horizons.

New Insights into Continental Deformation in Northwestern Tibet
A new surface velocity map shows strain localized along major strike-slip features, suggesting the central Tibetan Plateau is not deforming as a fluid in response to gravitational collapse.

Harnessing Remote Infrasound to Study Volcanic Eruptions
Data from the 2015 eruption of Chile’s Calbuco volcano suggest the international network built to monitor nuclear explosions may also be used to detect and characterize volcanic activity.
