Steam-driven eruptions, both phreatic and hydrothermal, expel exclusively fragments of non-juvenile rocks disintegrated by the expansion of water as liquid or gas phase. As their violence is related to the magnitude of the decompression wor...
Groundwater Loss and Aquifer System Compaction in San Joaquin Valley During 2012-2015 Drought [0.03%]
圣华金谷地下水损失及含水层系统压实(2012—2015)

California's millennium drought of 2012-2015 severely impacted the Central Valley aquifer system and caused permanent loss of groundwater and aquifer storage capacity. To quantify these impacts within the southern San Joaquin Valley, we ana...
Seismic Imaging of the North American Midcontinent Rift Using S-to- P Receiver Functions [0.03%]
利用S到P接收函数对北美中部裂谷进行地震成像研究

Ben Chichester et al.
North America's ~1.1-Ga failed Midcontinent Rift (MCR) is a striking feature of gravity and magnetic anomaly maps across the continent. However, how the rift affected the underlying lithosphere is not well understood. With data from the Sup...
Extrinsic Elastic Anisotropy in a Compositionally Heterogeneous Earth's Mantle [0.03%]
地球异质成分地幔中的固有弹性能各向异性
Manuele Faccenda,Ana M G Ferreira,Nicola Tisato et al.
Manuele Faccenda et al.
Several theoretical studies indicate that a substantial fraction of the measured seismic anisotropy could be interpreted as extrinsic anisotropy associated with compositional layering in rocks, reducing the significance of strain-induced in...
Effects of Induced Stress on Seismic Waves: Validation Based on Ab Initio Calculations [0.03%]
基于从头算的诱导应力对地震波影响的研究及验证

Jeroen Tromp et al.
When a continuum is subjected to an induced stress, the equations that govern seismic wave propagation are modified in two ways. First, the equation of conservation of linear momentum gains terms related to the induced deviatoric stress, an...
Earthquake Nucleation Size: Evidence of Loading Rate Dependence in Laboratory Faults [0.03%]
震源大小与加载速率的关系:实验室断层的证据

Simon Guérin-Marthe et al.
Recent Global Positioning System observations of major earthquakes such as the 2014 Chile megathrust show a slow preslip phase releasing a significant portion of the total moment (Ruiz et al., 2014, https://doi.org/10.1126/science.1256074)....
Marine Geophysical Investigation of the Chain Fracture Zone in the Equatorial Atlantic From the PI-LAB Experiment [0.03%]
源于PI-LAB实验的赤道大西洋链断裂带海洋地球物理研究
Nicholas Harmon,Catherine Rychert,Matthew Agius et al.
Nicholas Harmon et al.
The Chain Fracture Zone is a 300-km-long transform fault that offsets the Mid-Atlantic Ridge. We analyzed new multibeam bathymetry, backscatter, gravity, and magnetic data with 100% multibeam bathymetric data over the active transform valle...
Geodetic Observations of Weak Determinism in Rupture Evolution of Large Earthquakes [0.03%]
大地震破裂演化的弱决定性地球观测研究

D E Goldberg et al.
The moment evolution of large earthquakes is a subject of fundamental interest to both basic and applied seismology. Specifically, an open problem is when in the rupture process a large earthquake exhibits features dissimilar from those of ...
Flexible Coupling in Joint Inversions: A Bayesian Structure Decoupling Algorithm [0.03%]
联合反演中的柔性耦合:一种贝叶斯结构解耦算法

When different geophysical observables are sensitive to the same volume, it is possible to invert them simultaneously to jointly constrain different physical properties. The question addressed in this study is to determine which structures ...
Marchenko-Based Target Replacement, Accounting for All Orders of Multiple Reflections [0.03%]
基于マルケンコ方程的目标替换方法描述全部多次反射效应

Kees Wapenaar
In seismic monitoring, one is usually interested in the response of a changing target zone, embedded in a static inhomogeneous medium. We introduce an efficient method that predicts reflection responses at the Earth's surface for different ...
