GIA imaging of 3-D mantle viscosity based on palaeo sea level observations - Part I: Sensitivity kernels for an Earth with laterally varying viscosity [0.03%]
基于古海平面观测的三维地幔黏度GIA成像 - 第一部分：具有横向变化黏性的地球的敏感性核函数

A key initial step in geophysical imaging is to devise an effective means of mapping the sensitivity of an observation to the model parameters, that is to compute its Fréchet derivatives or sensitivity kernel. In the absence of any simplif...
Characterizing the porosity structure and gas hydrate distribution at the southern Hikurangi Margin, New Zealand from offshore electromagnetic data [0.03%]

The dynamics of accretionary prisms and the processes that take place along subduction interfaces are controlled, in part, by the porosity and fluid overpressure of both the forearc wedge and the sediments transported to the system by the s...
3-D shallow shear velocity structure of the Jakarta Basin from transdimensional ambient noise tomography [0.03%]

Situated on the northern coast of the Indonesian island of Java, Jakarta and its metropolitan area (Greater Jakarta) are subject to significant earthquake hazards from a subduction zone south of Java and nearby active crustal faults. The se...
From offshore to onshore probabilistic tsunami hazard assessment via efficient Monte Carlo sampling [0.03%]
基于高效蒙特卡罗采样的近海与滨海概率型海啸危险性评估方法研究

Gareth Davies et al.
Offshore Probabilistic Tsunami Hazard Assessments (offshore PTHAs) provide large-scale analyses of earthquake-tsunami frequencies and uncertainties in the deep ocean, but do not provide high-resolution onshore tsunami hazard information as ...
Extraction of GRACE/GRACE-FO observed mass change patterns across Antarctica via independent component analysis (ICA) [0.03%]
基于独立成分分析（ICA）的南极洲重力恢复与气候实验（GRACE/GRACE Follow-On）重力观测质量变化提取研究
Tianyan Shi,Yoichi Fukuda,Koichiro Doi et al.
Tianyan Shi et al.
Here we qualitatively analyse the mass change patterns across Antarctica via independent component analysis (ICA), a statistics-based blind source separation method to extract signals from complex data sets, in an attempt to reduce uncertai...
Application of multiscale magnetotelluric data to mineral exploration: an example from the east Tennant region, Northern Australia [0.03%]
多尺度磁电测深数据在矿产勘查中的应用——以澳大利亚北部Tennant地区为例
Wenping Jiang,Jingming Duan,Michael Doublier et al.
Wenping Jiang et al.
The footprint of a mineral system is potentially detectable at a range of scales and lithospheric depths, reflecting the size and distribution of its components. Magnetotellurics is one of a few techniques that can provide multiscale data s...
Application of a convolutional neural network for seismic phase picking of mining-induced seismicity [0.03%]
卷积神经网络在矿山诱发地震相位拾取中的应用

Sean W Johnson et al.
Monitoring mining-induced seismicity (MIS) can help engineers understand the rock mass response to resource extraction. With a thorough understanding of ongoing geomechanical processes, engineers can operate mines, especially those mines wi...
Two-dimensional Bayesian inversion of magnetotelluric data using trans-dimensional Gaussian processes [0.03%]
基于变维高斯过程的磁oteluric数据二维Bayesian反演

Bayesian inversion of electromagnetic data produces crucial uncertainty information on inferred subsurface resistivity. Due to their high computational cost, however, Bayesian inverse methods have largely been restricted to computationally ...
Separation of geophysical signals in the LAGEOS geocentre motion based on singular spectrum analysis [0.03%]
