earthquake

Earthquake of Olesky area and surrounding areas within the Lviv region and in particular some features of earthquakes in V. Mosty (1875) and Komarno (2007) as well as influence on a given territory from Vrancea zone earthquakes (in particular, the earthquake in 1838) are analyzed. According to foreign reports about the influence of the method of hydraulic fracturing on seismicity the conclusion about possible changes of seismic regime of the area and increase the possible danger to water resources of Lviv region from shale gas extraction were made. 

Multiscale pre-, co- and post-seismic deformation processes from the local, regional and strongest world's earthquakes in the Earth lithosphere according to the extenzometric measurements on the short quarts extensometer of RGS “Beregove” in Ukrainian Transcarpathians are considered. Some features of the propagation of such strains in the Eurasia lithosphere are traced.

The results of magnetotelluric study in the earthquake source zone of Olyutor earthquake (20.04.2006 г.; Мw=7,6) have been represented.

Purpose. The purpose is review and analysis of the modern publications of the experimental measurements data of geophysical parameters investigations of East European Platform lithosphere and its surroundings. Methodology. The methodology includes a detailed complex analysis of the deep structure and seismotectonic activity in the stable regions. Results. Analysis of anomalies of electric conductivity in tectonically stable regions showed that within the ancient platforms that were previously attributed to aseismic, rarely, the catastrophic earthquakes with high intensity occur.

Goal: - to analyze the focal parameters of Crimean earthquakes determined from records of analog and digital seismic stations; - to draw a conclusion about the degree of their correspondence and continuity to the properties and regularities received earlier with the use of only analogue equipment. Methodology. We have chosen the earthquakes in the south of  Ukraine registered parallelly by two kinds of seismographs at the “Simferopol” and “Alushta” stations.

Purpose. In world practice there are observations of variations of induction vectors related to geodynamic processes. The purpose of this work is to compare time series of induction vector components at two Japanese stations Esashi (ESA) and Mizusawa (MIZ), located on the east coast of Honshu island at a distance of 19 km from each other, with a seismic activity in the region. Methodology.

Purpose. To perform a comparative analysis of record forms and earthquake spectrograms and explosions in quarries and mines what located in area of Kriviy Rih iron-ore basin (Kryvbas) for detection of seismic event signs of different nature this region with magnitude Mb ≥ 3,0 is the research object. Methods.

Purpose. The purpose of research is to determine the possibility of using of infrasound measurements that carried out in Ukraine for verification of registered seismic events and using of infrasound method as one of the criteria for their identification. Methodology. Registration of seismic and infrasonic signals carried out with using of geophysical networks of Main Center of Special Monitoring (MCSM). To register infrasound the small aperture acoustic group systems are used, allowing directional monitoring of events.

Purpose. The main goal is to find the relationship between the generalized parameters of the vertical displacement of the earth's surface and the background seismic activity of the European continent by means of GNSS- technology. Establishing the relationship between these two phenomena is one way to predict the overall degree of seismic activity of the area. Methodology. One way of determining the vertical movements of the crust is GNSS- measurement.

Sumatra earthquake was accompanied by the similar strains on four deformation stations. This phenomenon can be explained by the unstable state of geological environment in the field of the future earthquake. It is necessary to use the data GPS side by side with the station data in order to obtain the reliable results.
