Seismogenic structures of the collision-subduction zone in the eastern Taiwan
2020<p>The Taiwan orogenic belt is relatively young and active with an ongoing arc-continent collision since the middle Miocene. In this study, we systematically investigate the use of seismic tomography, focal-mechanism and distribution of earthquakes to analysis the seismogenic patterns in the collision-subduction zone in the ...

GEOELECTRICAL CHARACTERISTICS OF SEISMOGENIC STRUCTURE IN THE BAIKAL PREDICTION TESTING GROUND
Russian Geology and Geophysics, 1993Geoelectrical characteristics of the upper crust of the southern section in the Baikal prediction testing ground, including the northeastern wing of the Selenga depression, from village of Kudara to village of Kluchi-Stvolovaya on the northeast are given in the paper.

Relocation and seismogenic structure of the 1998 Zhangbei-Shangyi earthquake sequence
Acta Seismologica Sinica, 2002On January 10, 1998, an earthquake of ML=6.2 occurred in the border region between the Zhangbei County and Shangyi County of Hebei Province. This earthquake has been the most significant event occurred in the northern China in the recent years. Historical seismicity in the Zhangbei-Shangyi region was very low.

The aegean region — Seismogenic properties of deep seismically active structures
Studia Geophysica et Geodaetica, 1994The seismicity depth pattern, seismic energy and b-value depth variation in the Hellenic Wadati-Benioff zone and the overlying continental plate in the Aegean region for the period 1901–1982 are studied separately on the basis of a recent seismotectonic model [1]. The results obtained show that the W and E flanks of the Hellenic Wadati-Benioff zone, as

Seismogenic structures in western Yunnan revealed by three-dimensional magnetotelluric imaging
2020<p>Influenced by the extrusion of Tibetan blocks and Indo-Burmese collision, the region in western Yunnan is associated with active seismicity and Quaternary volcanoes. Based on broadband magnetotelluric data collected in western Yunnan, we obtain a three-dimensional crustal electrical resistivity model after various data ...

Seismogenic Structure of the April 20, 2013, Lushan Ms7 Earthquake in Sichuan
Acta Geologica Sinica - English Edition, 2013Abstract:At 08:02 on April 20, 2013, a Ms7.0 earthquake occurred in Lushan, Ya'an, in the Longmenshan fault zone, Sichuan. The epicenter was located between Taiping Town and Shuangshi Town, Lushan County and the maximum earthquake intensity at the epicenter reached class IX. Field investigations in the epicenter area found that, although buildings were

Kashmir basin situated in tectonically active area NW Himalaya is surrounded by a number of seismogenic faults. In the present study, the structures are identified using the edge enhancement filters, false colour composite and DEM derived products like shaded relief, aspect, slope, drainage network, and 3D profiling.

We summarize seismogenic structures in four regions of active convergence, each at a different stage of the collision process, with particular emphases on unusual, deep-seated seismogenic zones that were recently discovered. Along the eastern Hellenic arc near Crete, an additional seismogenic zone seems to occur below the seismogenic portion of the ...

Seismogenic structures of the 2006 ML4.0 Dangan Island earthquake offshore Hong Kong
Journal of Ocean University of China, 2018The northern margin of the South China Sea, as a typical extensional continental margin, has relatively strong intraplate seismicity. Compared with the active zones of Nanao Island, Yangjiang, and Heyuan, seismicity in the Pearl River Estuary is relatively low. However, a ML4.0 earthquake in 2006 occurred near Dangan Island (DI) offshore Hong Kong, and
