AbstractA new method for estimating the self-noise of the measuring channel of a seismometer is proposed, taking into account the linear relationship between the signal and noise. The method extracts noise using records of two identical measuring channels on the example of the SM-3KV short-period seismometer with an operating frequency range of 0.5...

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 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...

AbstractTo determine the coordinates of earthquakes, the Republic of Armenia (RA) Seismic Survey uses algorithms based on the Geiger method. All these algorithms use only one travel time curve (one velocity curve) for the entire study area and all stations of the RA seismological network. Despite the fact that a number of studies have been devoted ...

AbstractA new energy classification method is proposed for acoustic events recorded in laboratory experiments on rock destruction. The method analyzes the coda waves of acoustic emission (AE) events. Coda waves are considered as reverberation of the acoustic field in the test sample. The new classification was tested on two experiments carried out ...

AbstractThe source parameters of earthquakes in the Arctic during the entire instrumental period were calculated using a small number of stations, which in addition were remote from each other. Furthermore, during the 20th century, the source parameters of Arctic earthquakes were most often calculated from bulletin data from only part of the seismi...

AbstractCatalogs of weak seismic events (M ≤ 4) in Turkey and Iran were analyzed to identify signs of their contamination with blasts. A well-pronounced predominance of the number of seismic events and a decrease in their average magnitude in the period from 10:00 to 17:00 LT were found. The epicenters of seismic events that occurred in this time i...

AbstractThe article presents the results from a study of dynamic characteristics of the response of a high-rise building under the seismic impact of a series of southern Baikal earthquakes in 2007–2008. One earthquake used in the study, the Kultuk, occurred on August 27, 2008, at 10:35 LT (UTC +8). The epicenter of tremors was at the bottom of Lake...

AbstractAn automatic vertical alignment method is presented and analyzed for an absolute laser ballistic gravimeter. The method uses a high-speed video camera to record the displacement trajectory of glare from the measuring beam reflected from a corner reflector when the test body is in free fall. The magnitude and direction of the measuring beam ...
