South-eastern Tibet rotates clockwise around the eastern Himalayan syntaxis due to the eastward extrusion of the eastern Tibetan lithosphere and it attracts much attention as a window for studying the dynamics of continental collision between India and Eurasia. Competing geodynamic models to describe the deformation of the eastern Tibet have been t...

Mining-induced earthquakes (MIEs) in underground coal mines have been a common phenomenon that easily triggers rock bursts, but the mechanism is not understood clearly. This research investigates the laws of focal mechanism and source parameters based on focal mechanism and source parameters analysis of MIEs in three frequent rock burst areas. The ...

Emerging high-performance computing systems, combined with increasingly detailed 3-D Earth models and physically consistent numerical wave propagation solvers, are opening up new opportunities for urgent seismic computing. This may help, for instance, to guide emergency response teams in the wake of large earthquakes. A key component of urgent seis...

AbstractThe article presents the results of studying the source of the 2015 Kenekesir earthquake and its aftershock sequence. The earthquake occurred in the Archman–Nokhur tectonic node zone, where the northwest orientation of the Central Kopet Dag faults changes to the northeast orientation of the Western Kopet Dag faults. The actual rupture plane...

AbstractThis study is concerned with Western and Central Tien-Shan. It is an area of intracontinental collision and is of great interest for the study of the geodynamic processes that are occurring in the crust. The area of study was investigated using the method of seismotectonic deformation (STD). The STD was calculated on the basis of the approa...

AbstractWhen conducting seismological studies, initial data from different international seismological agency databases are often used. Determinations of earthquake hypocentral coordinates by different seismological agencies yield different results, associated with different observation systems, processing methods, and high-speed models. This can s...

AbstractThe results of studying the Bystrinskii earthquake of September 21, 2020, in the southern Baikal region are presented. Its geodynamic position, focal mechanism, and basic parameters are indicated. The deformation monitoring data showing six days of anomalous growth of rock deformations preceding the earthquake are provided. It is shown that...

Abstract—The digital seismic network in Kamchatka deployed in 2006–2010 provided a fundamental possibility for calculating seismic moment tensor (SMT) of Kamchatka earthquakes from broadband waveforms recorded by regional stations. The paper describes the method for calculating SMT for the earthquakes with pure double couple (DC) mechanism based on...

AbstractOn January 26, 2020, a moderate-sized earthquake (ML ~ 4.6) located in the Palnadu sub-basin of Cuddapah basin was felt both in the states of Telangana and Andhra Pradesh. The earthquakes prior and after the ML 4.6 are located close to the thrust and along the periphery of the backwaters of the Pulichintala Reservoir. About 965 earthquakes ...

Abstract—One of the strongest deep earthquakes that occurred on August 18, 2018, MW = 8.2, h = 600 km off the Tonga Islands is analyzed. This earthquake is notable for having a powerful aftershock sequence which is generally untypical of the deep earthquakes and which justifies considering this quake as a unique seismic event. Based on the first-da...
