SEISMOTECTONIC DEFORMATION OF THE LITHOSPHERE IN THE PAMIR AND ADJACENT TERRITORIES

open access: yesГеодинамика и тектонофизика, 2020
В работе исследована область Памира и Тянь-Шаня, которая является зоной внутриконтинентальных столкновений и представляет большой интерес для изучения геодинамических процессов, протекающих в земной коре и литосфере. Указанная область исследована методом

DiTingMotion: A deep-learning first-motion-polarity classifier and its application to focal mechanism inversion

open access: yesFrontiers in Earth Science, 2023
Accurate P-wave first-motion-polarity (FMP) information can contribute to solving earthquake focal mechanisms, especially for small earthquakes, to which waveform-based methods are generally inapplicable due to the computationally expensive high ...

IGF-I receptor phosphorylation is impaired in cathepsin X-deficient prostate cancer cells [PDF]

open access: yes, 2012
The cysteine-type peptidase cathepsin X is highly upregulated in several cancers and presumably promotes tumor invasion through bypassing cellular senescence. Here, we present first evidence that the underlying mechanism may involve the regulation of the

Focal mechanism determination for voIcanic microearthquakes

open access: yesAnnals of Geophysics, 1994
Classical methods to infer focal mechanisms from first P wave motions are of limited use for the analysis of small magnitude events occurring in volcanic areas, due to structure complexity.

Edges of overlying seams as a factor responsible for strong mining tremors occurrence during underground hard coal extraction in the light of seismic moment tensor inversion method [PDF]

open access: yesE3S Web of Conferences, 2019
Physical processes occurring in the focus of tremor can be identified by solving a focal mechanism via the seismic moment tensor inversion method. In this article the estimation of focal mechanisms of strong mining tremors (according to Polish law ...

FMHex20: An earthquake focal mechanism database for seismotectonic analyses in metropolitan France and bordering regions

open access: yesBSGF - Earth Sciences Bulletin, 2021
We present a compilation of over 1700 focal mechanisms for nearly 1300 earthquakes in metropolitan France and bordering regions of Western Europe. It is based on both published and unpublished sources (articles, reports, observatory websites) for which ...

The 1980, 1997 and 1998 Azores earthquakes and its seismotectonic implications [PDF]

open access: yes, 2007
We have studied the focal mechanisms of the 1980, 1997 and 1998 earthquakes in the Azores region from body-wave inversion of digital GDSN (Global Digital Seismograph Network) and broadband data. For the 1980 and 1998 shocks, we have obtained strike– slip

Application of simulated annealing to focal mechanism determination [PDF]

open access: yes, 2015
Simulated annealing (SA) is known as one of the efficient methods for global optimization. It allows for getting an optimal solution by jumping out of local minimum.

Risk Assessment of Fracturing Induced Earthquake in the Qiabuqia Geothermal Field, China

open access: yesEnergies, 2020
In order to reduce the harm of induced earthquakes in the process of geothermal energy development, it is necessary to analyze and evaluate the induced earthquake risk of a geothermal site in advance.
