The First Slow-Slip Events Seen off Southern Costa Rica
Five events observed off the Osa Peninsula shed new light on the role that these small, slow earthquakes can play in strain accumulation and tsunami hazards along subduction zones.
Desert Landscape Evolution Controlled by Storm Intensity
A new study in the Negev Desert finds that long-term erosion of a desert escarpment occurs in drier areas where intense storms are most frequent.
Illuminating the Complex Structural Fabric Beneath the European Alps
A new study investigates the dynamics of the complex continental collision that formed the European Alps and reveals how structural alignments change with depth.
Earthquakes Have Preparatory Stage Years Before Rupture
Tidally induced seismicity increased locally before the 2019 Ridgecrest earthquake, suggesting that fault sensitivity to stress increases in the years immediately before large earthquakes.
Fluid Release from Subducted Slabs Without Percolation Flow
A new study demonstrates the absorption mechanism of H2O release out of subducting slabs, making the previous hypothesis of dehydration embrittlement unnecessary.
Flowing Crust Pushes Faults on Their Backs
Puzzlingly shallow faults in western Türkiye are likely getting a boost from below.
Shifts in Tectonic Plates Change Biodiversity
A 36-million-year cycle of marine biodiversity booms and busts matches the movements of plate tectonics, linking what happens deep below the ocean to what’s happening in it.
A New, Underground Atlas of Subduction Zones
Submap merges graphic design with geodynamics, providing a fast, free, and user-friendly resource to map subduction zones.
Talc May Make Mexico’s Subduction Zone More Slippery
Production of the weak, water-bearing mineral at the interface between the Cocos and North American Plates could contribute to the occurrence of poorly understood episodic tremor and slow slip.
