New data synthesis suggests that varying rates of trench retreat along the margin of the Gondwana supercontinent were responsible for the curvature of the Tasmanide mountain chains.Read More »Geology & Geophysics
New methods of machine learning are bringing the phase arrival time and polarity picking used for automatic determination of earthquake fault planes to accuracies better than human analysists.Read More »Geology & Geophysics
Cross-correlations of ambient seismic noise are combined with well log data to image shallow crustal basement features in the Ebro Basin in Spain.Read More »Geology & Geophysics
Mechanical modeling suggests that previous, undetected eruptions released tectonic stress near the ice-covered Bárðarbunga volcano.Read More »Geology & Geophysics
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.Read More »Geology & Geophysics
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.Read More »Geology & Geophysics
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.Read More »
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.Read More »
