AbstractThe article discusses the results of processing instrumental and macroseismic observations of the strongest earthquake in Central Baikal in the last 60 years, which occurred on December 9, 2020 (MW = 5.5), as well as its aftershocks. The event was named the Kudara earthquake, after the locality where the maximum intensity of shocks was reco...

AbstractThe paper presents seismological, forecasting, and seismotectonic data on the strong March 25, 2020 earthquake in the Northern Kurils. The collected materials on an unusual deep lithospheric earthquake in the border area of the Northern Kurils and Southern Kamchatka made it possible to understand the structure of the source of this event, a...

Since landing in late 2018, the InSight lander has been recording seismic signals on the surface of Mars. Despite nominal prelanding estimates of one to three meteorite impacts detected per Earth year, none have yet been identified seismically. To inform revised detectability estimates, we simulated numerically a suite of small impacts onto Martian...

Seismic source parameters of small to moderate sized intraplate earthquakes that occurred during 2002–2009 in the tectonic blocks of Kachchh Rift Basin (KRB) and the Saurashtra Horst (SH), in the stable continental region of western peninsular India, are studied through spectral analysis of shear waves. The data of aftershock sequence of the 2001 B...

This work focuses on the evaluation of the seismic hazard for Romania using earthquake catalogues generated by a Monte Carlo approach. The seismicity of Romania can be attributed to the Vrancea intermediate-depth seismic source and to 13 other crustal seismic sources. The recurrence times of large magnitude seismic events (both crustal and subcrust...

The generalized observations over hypocenters of the strongest mining-induced events have shown that relative deformation occurs as movement along the existing faults. From the experimental evidence, transition of a section of a fault to meta-stable state goes with the decrease of its dynamic shearing stiffness. The alteration of the mechanical pro...

The probability distribution of far-field tsunami amplitudes is explained in relation to the distribution of seismic moment at subduction zones. Tsunami amplitude distributions at tide gauge stations follow a similar functional form, well described by a tapered Pareto distribution that is parameterized by a power-law exponent and a corner amplitude...

The authors analyze mine logs of seismic events in Poland, Finland, Canada, Russia and South Africa. For the analyzed events, induced seismic energy varies by 2–3 orders of magnitude at the same value of seismic moment. The upper and lower limits of the range correspond to “stiff” and “soft” sources, respectively. The most probable cause of the wid...

The variations in the intensity of the global seismic process during the 20th and beginning of the 21st centuries are analyzed. It is established that the evolution of the global seismic process is marked by a trend of a certain quasi-periodicity in the release of seismic energy. The analysis of the lithospheric seismicity during 113 years has show...

The authors calculate possible errors in characterization of low-magnitude seismicity sources using the Brune model and methods of identification of seismic event energy class and local magnitude. The adequacy of the model has been proved by comparing its results with the recordings of seismic vibrations in the North Ural Bauxite Mine. The errors d...
