Unearthing the Cause of Slow Seismic Waves in Subduction Zones
Researchers look to the fossil rock record to unearth the driving forces for variable seismic speed through subduction zones.
The Birth, Growth, and Death of Continents
There are various explanations for how the Earth’s continents form, develop, and change but challenges remain in fully understanding the driving forces behind plate tectonics on our planet.
Measuring Sea Level Rise Along the Coast
Scientists created a global map of vertical land motion to show how the solid ground is moving relative to the planet’s rising seas.
Extinct Style of Plate Tectonics Explains Early Earth’s Flat Mountains
The geologic record suggests that despite Earth’s hot, thin crust during the Proterozoic, mountains were still able to form thanks to an extinct style of crustal deformation.
A Novel Thermobarometer to Infer Mantle Melting Conditions
The algorithm RevPET automatically reverses the complex multi-phase fractional crystallization path of oceanic basalts and offers new perspectives for advancing mantle thermobarometry.
Himalayan Tectonics in the Driver’s Seat, Not Climate?
Earth’s oscillating climate is a natural guess to explain cyclic patterns in erosion, but new sediment data suggests that cyclicity may emerge from tectonic processes adding material to the Himalaya.
Subduction Zone Earthquakes: Fast and Slow, Weak and Strong
What causes slow earthquakes in subduction zones? New insights from numerical models suggest that a mixture of strong and weak rocks might be the cause.
Earth’s Continents Share an Ancient Crustal Ancestor
How did today’s continents come to be? Geological sleuths found clues in grains of sand.
Swipe Left on the “Big One”: Better Dates for Cascadia Quakes
Improving our understanding of hazards posed by future large earthquakes on the Cascadia Subduction Zone requires advancements in the methods and sampling used to date and characterize past events.
