Seafloor Shapes on the Flanks of Mid-Ocean Ridges Linked to Magma Supply
New research suggests the source of morphologic variation on mid-ocean ridges might be deeper than scientists thought.
Subducted Seamounts May Lead to Larger Earthquakes
New findings show that underwater mountains may increase friction along subduction zones, building up stress and making larger ruptures more likely.
Los primeros eventos de deslizamiento lento observados en el sur de Costa Rica
Cinco eventos observados en la Península de Osa revelan nueva información sobre el papel que estos pequeños y lentos terremotos pueden desempeñar en la acumulación de tensión y riesgos de tsunami a lo largo de las zonas de subducción.
Future Supercontinent Will Be Inhospitable for Mammals
Pangea returns in 250 million years, and it’s not looking good for us.
Piecing Together the Roots of the Ancient Australian Continent
Mineral compositions from numerous volcanic rocks that sample the mantle keel beneath Western Australia’s Kimberley Craton reveal the temperature and mineralogy that explain its long-lived stability.
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.
