Abstract The collision between India and Eurasia mobilizes multiple processes of continental tectonics. However, how deformation develops within the lithosphere across Tibetan Plateau is still poorly known a synoptic view missing. Here, we exploit an extensive geodetic observatory to resolve kinematics this diffuse plate boundary arrangement various mechanisms down upper-mantle depths. three-dimensional velocity field compatible with underthrusting below central Himalayas delamination...
Abstract A three‐dimensional (3‐D) resistivity model around the 2014 M s 6.5 Ludian earthquake was obtained. The shows that aftershocks were mainly distributed in a shallow inverse L‐shaped conductive angular region surrounded by resistive structures. presences of this zone may be key factor leading to severe damage and surface rupture earthquake. northwest trending local belt along Baogunao‐Xiaohe fault interrupts northeast at Zhaotong‐Lianfeng middle crust, which seismogenic structure main...
Abstract Stress transfer between earthquakes is recognized as a fundamental mechanism governing aftershock sequences. A common approach to relate stress changes seismicity rate the rate‐and‐state constitutive law developed by Dieterich: these elements are foundation of Coulomb‐rate‐and‐state (CRS) models. Despite successes Coulomb hypothesis and formulation, such models perform worse than statistical in an operational forecasting context: one reason that subject large uncertainties intrinsic...
Abstract Gongga Shan (GGS) is the highest mountain on eastern margin of Tibetan Plateau. However, mechanism for uplift still unclear due to a lack detailed geophysical studies. Inversion an array magnetotelluric data at 120 sites produced 3D resistivity model that revealed GGS massif characterized by high upper crust underlain westward dipping resistor middle crustal depths interpreted as underthrust Yangtze Craton (YC). A thin conductive layer sandwiched between these two zones resistivity....
Abstract Upward shifts of alpine treelines and shrub expansion are occurring under climate change, Abies faxoniana (AF) Rhododendron lapponicum (RL) may become distributed at higher altitudes. How do abiotic factors litter quality modulate the effects soil fauna on carbon release in this context? A field decomposition experiment involving foliar AF RL was conducted along an elevation gradient encompassing coniferous forest, shrubland meadow by using litterbags with different mesh sizes (3...

Thermal instabilities below the seismogenic zone by shear heating and temperature-weakening friction drive slow slip, tremors.
Both aftershocks and geodetically measured postseismic displacements are important markers of the stress relaxation process following large earthquakes. Postseismic can be related to creep‐like in vicinity coseismic rupture by means inversion methods. However, results slip inversions typically non‐unique subject uncertainties. Therefore, we explore possibility improve mechanical constraints. In particular, take into account physical understanding that deformation is stress‐driven, occurs...
SUMMARY Very clear coseismic electric and magnetic signals accompanying seismic waves were observed during the 2017 Mw 6.5 Jiuzhaigou earthquake, which took place in western China. In order to understand generation mechanism of these signals, we simulate responses this specific earthquake based on three mechanisms, namely, electrokinetic effect, motional induction effect rotation coil-type magnetometer. We conduct simulations using a point source model realistic layered earth compare data...
Abstract We propose a numerical method for calculating exact all‐time apparent resistivity time‐domain transient electromagnetic method. According to the behaviour of kernel function Y' ( Z ) ∂B z /∂T , can be distinguished into early‐time > 1.6), transition point = 1.6) and late‐time < stages central loop configuration. First resisitivities are calculated using earlytime expressions then curve is founded by combining two over point. Although Y B single valued, there also 1.6 should...
