受2008年汶川地震后收集的位置数据的约束的计算机建模表明,下地壳的粘性比其下方的上地幔要小。
Hazards & Disasters
Faults in Oceanic Crust Contribute to Slow Seismic Waves
New high-sampling rate measurements of fluid pressures in oceanic crust reveal unresolved fractures and pathways for fluid flow.
Pro-Poor Flood Risk Management Can Reduce Urban Inequality
Rich people’s aversion to flood risk results in poor people living in the most vulnerable locations poverty. Pro-poor flood risk management policies could have a significant impact on inequality.
Rock Structure Explains Slow Seismic Waves
New findings contrast with a prevailing hypothesis for low seismic velocity in subduction zones.
The Far-Reaching Consequences of Wildfire Smoke Plumes
Smoke from wildfires burning in the western United States carries harmful pollutants across the country.
How the Armero Tragedy Changed Volcanology in Colombia
The deadly eruption of Nevado del Ruiz in 1985 made Colombian volcanologists realize that studying natural phenomena was irrelevant if they could not share their knowledge to avoid predictable tragedies.
Tubos de lava terrestres podrían ofrecer información sobre la vida extraterrestre
Una nueva investigación encuentra que Actinobacteria en cuevas de lava fijan carbón y sobreviven independientemente de aportes superficiales, ofreciendo una nueva perspectiva en la investigación de la vida fuera de la Tierra.
New Theory Connects Tree Uprooting and Sediment Movement
Tree throw from extreme wind events plays an important role in the movement of sediment and erosion on forested hillslopes. A new theory offers a novel way to measure its impact.
Forecasting Compound Floods in Complex Coastal Regions
Coastal communities face more frequent floods in which rain, rivers, and ocean storm surge combine forces. A reliable system that accurately predicts inundation from these events is urgently needed.
Cyclone “Seed” Survival Affects Hurricane Season Intensity
Understanding how seed storms grow into full-blown hurricanes and typhoons could help predict hurricane season intensity in a changing climate.
