Volcano—Tectonic Interactions at Etna
Mapping of a 2018 earthquake that ruptured the eastern flank of Mount Etna shows that it occurred on a tectonic lineament that predates the volcano, and the kinematics match nearby tectonic domains.
Learning from a Disastrous Megathrust Earthquake
Ten years of interdisciplinary studies since the disastrous Tohoku-oki earthquake have improved our knowledge of earthquake-cycle processes and hazard, but prediction of such events remains elusive.
Subduction Initiation May Depend on a Tectonic Plate’s History
New seismic imaging study of the Puysegur Trench aims to solve one of the last major questions in plate tectonics.
A Closer Look at the Creation of a Metamorphic Sole
Detailing the development of the metamorphic sole beneath the Oman–United Arab Emirates ophiolite provides insight into subduction zone processes.
Past Climate Change Affected Mountain Building in the Andes
Increased glaciation in the North Patagonian Andes may have influenced tectonic dynamics over the past 7 million years, suggesting a connection between climate change and mountain-building processes.
Probing the Age of the Oldest Ocean Crust in the Pacific
A new study extends the calibration of the Mesozoic Sequence down to the Mid Jurassic with multiscale marine magnetic anomaly data, demonstrating extraordinarily high reversal frequency.
Cratons, Why Are You Still Here?
How have these continental relics from Earth’s early history survived the plate tectonic mixing machine?
Breaking Up Is Hard to Do, Especially for Continents
A decade-long research collaboration has revealed that the split between Africa and North America roughly 200 million years ago was more drawn out than previously thought.
Slipping and Locking in Earth’s Earthquake Factories
Geodetic observations collected during back-to-back decadal research campaigns have revealed crucial new insights into the start–stop and slow-motion behavior of subduction zones.
