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.
AGU Advances
Atoll Seismometer Detection of Solitary Ocean Waves
Seismic recordings from the South China Sea indicate that subtle, daily tilting of shorelines due to passing internal ocean waves can be measured on land, promising new constraints on ocean dynamics.
Magnetic Record of Early Nebular Dynamics
Magnetized particles in a meteorite suggest strong magnetic fields in the early solar nebula.
Steady but Slow Progress on the Long Road Towards Gender Parity
The historic disproportionate attrition of women among geoscience faculty is decreasing, but how long will it take to reach gender parity if current trends of progress continue?
Is Earth’s Albedo Symmetric Between the Hemispheres?
The two hemispheres feature the same planetary albedo despite a larger land fraction in the north, because storms over the southern ocean are cloudier than their northern counterparts.
Need for Rational Thinking for Predicting Floods and Droughts
To plan policies that manage flood and drought risk, is it sufficient to follow the science? The better path uses the best science, which draws insight from integrated multidisciplinary research.
Sedimentary Tepees Record Ocean Chemistry
Sedimentary structures from evaporative coastal environments indicate carbonate saturation, offer insight in mid-Mesozoic ocean chemistry and potentially even earlier times.
Permanence of Nature-Based Climate Solutions at Risk
Conserving native ecosystems helps sequester carbon and mitigate climate change, but new statistical modeling questions the permanence of California’s carbon-rich forests with climate change.
The Highs and the Lows of Megathrust Earthquakes
Why does low-frequency energy come from the shallow part of ruptures, and the high frequencies from deep?
Good, Soon, and Cheap – Earthquake Early Warning by Smartphone
Fixed smartphone networks can provide robust early warning of earthquakes at far lower costs than traditional scientific arrays, which is an important consideration for regions with limited resources.
