Deep underground forces explain earthquakes along San Andreas Fault（图）
Deep underground forces earthquakes San Andreas Fault
2020/9/18
On the segment of the San Andreas Fault near Parkfield, California, underground excitations -- beyond the depths where quakes are typically monitored -- lead to instability that ruptures in a quake."M...
板块构造学说为解释地表观测到的几乎全部地质现象提供了动力学机制，如，板块相对运动机制，远离彼此的大陆板块上相似古生物地理分区的形成，以及大陆穿过不同特定古气候带的原因等等。这些运动通过地幔下降和上涌分别对应的板块俯冲和海底扩张实现。板块运动本质上是地幔对流造成的。
Clogging mechanism in the process of reinjection of used geothermal water: A simulation research on Xianyang No.2 reinjection well in a super-deep and porous geothermal reservoir
Xianyang Super-deep and porous geothermal reservoir Reinjection Clogging mechanism
2018/3/23
In the process of geothermal exploitation and utilization, the reinjection amount of used geothermal water in super-deep and porous reservoir is small and significantly decreases over time. This has b...
Reconstruction of deep fluid chemical constituents for estimation of geothermal reservoir temperature using chemical geothermometers
High temperature geothermal fluid Multi-component geothermometer optimization Geothermal gases Analogue
2018/3/23
his paper elaborates the chemical constituent change principles of deep geothermal fluid during the process of upward movement. It summarizes research methods of hydrochemistry, isotope and numerical ...
A new study suggests that the common belief that the Earth’s rigid tectonic plates stay strong when they slide under another plate, known as subduction, may not be universal.Typically during subductio...
In search of evidence of deep fluid discharges and pore pressure evolution in the crust to explain the seismicity style of the Umbria-Marche 1997-1998 seismic sequence (Central Italy)
fluid geochemistry/seismicity porepressure field Umbria-Marche 1997-1998 seismic sequence
2015/9/30
Starting soon after the first main-shocks of the long seismic sequence which has occurred along the Umbria-Marche boundary since September 1997, fluid geochemistry surveying was accomplished (around 2...
Source signature processing in deep water, Gulf of Mexico: comparison between deterministic deconvolution and phase conjugation
oversampling source signature deconvolution
2015/9/29
The Center for Marine Resources and Environmental Technology has been developing a new method to improve the resolution of high-resolution seismic profiling. To achieve this the source signature is re...
Assessment of deep electrical conductivity features of Northern Victoria Land (Antarctica) under other geophysical constraints
Magnetovariations electrical conductivity lithosphere
2015/9/28
The lithospheric and crustal structure of the Victoria Land continental block (Antarctica) has been studied by geological and geophysical surveys. Among them magnetovariational investigations (MV) hav...
Crustal structure at the western end of the North Anatolian Fault Zone from deep seismic sounding
north Anatolian fault zone crustal structure deep seismic sounding
2015/9/28
The first deep seismic sounding experiment in Northwestern Anatolia was carried out in October 1991 as part of the "German - Turkish Project on Earthquake Prediction Research" in the Mudurnu area of t...
Strain pattern of the Southern Tyrrhenian slab from moment tensors of deep earthquakes:implications on the down-dip velocity
southern tyrrhenian seimin strain rate tensor down-dip velocity aseismic subduction
2015/9/28
Seismic strain is analysed along the slab face of the Southern Tyrrhenian subduction zone using focal mechanisms of deep earthquakes which occurred in the period 1960-1998. Results show that the slab ...
Deep-water turbidites as Holocene earthquake proxies:the Cascadia subduction zone and Northern San Andreas Fault systems
