South Moravia

On January 6, 2012, a moderate earthquake was observed in a region SE of Poznań (local magnitude ML = 3.6 according to Institute of Physics of the Earth, IPE). In this region, there haven‘t been known any historical earthquakes so far, and no natural seismic activity has been observed up to present. Similar rare occurrences of weak and moderate earthquakes were observed in a region near Kaliningrad in 2004 (sequence of events, local magnitude of strongest event being 5.0) and in south Moravia region near Znojmo in 2000 (local magnitude ML = 2.5). These facts show that even in seismically quiet regions occurence of weak to moderate seismic events (with value of magnitude ranging from 3 to 5) could be expected.

Rotation Of The Earth

The problem of the correlation of the global dynamic phenomenon “Chandler wobble” with the local dynamics in different parts of the Earth’s crust and lithosphere is wide of the solution. In this study, an attempt was made to approach the solution by analyzing the temporal variations of local seismic activity in the restricted geospace volumes (GSV) within the uniform seismoactive regions. The driver of Chandler wobble is the deep mantle – the most hard and most massive Earth’s layer, whose large inertia tensor value is able to keep up Chandler’s specific rotation of the Earth for a long time. We use the geocentric coordinate system where daily rotation is absent. In this system Chandler wobble is very slow rotation of the Earth around the current equatorial axis (the pole of which is denoted as EP14). Probably, this slow rotation can influence on the seismic events in the GSV. This influence is proposed to determine by the some statistical parameter EP14gsv that indicates the most typical position EP14 on equator when the most part of the earthquakes have occurred in the given GSV. For some geospace volumes the distribution indicates certain longitudes, where the number of seismic events is maximal or minimal.

abstract Seismic events reported to have occurred in the USSR in 1971 are studied to assess the seismic monitoring problem as it may occur in the context of a complete test-ban treaty. Available epicenter data of a total of 199 events, 180 earthquakes and 19 explosions, are presented. Focal depth estimates reported by the National Oceanic and Atmospheric Administration, U.S., and the Institute of Physics of the Earth, Moscow, are compared. Identification parameters determined using short- and long-period data from Hagfors Observatory and supplementary short-period data from the Yellowknife array station in Canada are presented. To study the combined operative efficiency and applicability of available identification parameters, the reported depth estimates and the identification data are assessed in a defined way.

The article shows the monitoring results of the Ural region seismic network in 2013. It describes the seismic stations and registration abilities of the network. The analysis of seismic activity in Ural in 2013 and infor-mation about changes of the regional seismic regime since 2006 are given. The seismicity in the Ural is unique as it is presented by a wide spectrum of natural earthquakes (tectonic, earthquakes due to collapse, impact) as well as induced earthquakes (explosions, rock falls, rockbursts). Whereby the number of explosions in the region predominates among other seismic events, the number of rockbursts is much more than tectonic earth-quakes. A structural ordering can be seen for tectonic earthquakes. They tend to the basic geologic structure of the region to the Main Ural Fault. The induced events tend to mining regions. Also, there is a weak scat-tered seismicity that is typical for platform territories. Acting since 1999 the regional seismic network pro-vides the representative registration on the magnitude level ML≥2.5. In general in 2013 in Ural it was regis-tered 173 seismic events, and their basic seismic parameters were determined. The common number of in-dustrial explosions was 173. The summarized seismic explosions energy was 3.99E+9 Joules. The number of rockbursts was 29; their seismic energy was 2.82E+9 Joules. The five tectonic earthquakes made the min-imal contribution to the seismicity of the region. The unique event registered by seismic network was the ex-plosion of Chelyabinsk meteorite, and its parameters are shown in the article. Parameters of all mentioned above seismic events are presented in catalogue. The strongest events with ML≥3.0 including Chelyabinsk meteorite explosion, are considered separately, including their seismograms and parameters provided by other international seismic centers. The article shows the map with the actual locations of regional seismic stations and event epicenters in 2013. Generally the seismic regime of the region in 2013 was quite calm; the summarized seismic explosions energy was low. The trend to the seismic activity decay continues since 2010. The location of the natural and induced seismic events in space confirms the active zones previously determined.

The control of the geological environment is one of the most important tasks of the seismological monitoring in the territory of Belarus. The seismological monitoring in Belarus is carried out with a system of continuous round-the-clock computer-aided observations of the seismic events of natural and artificial origin in a wide range of distances and energies. The major task of the seismic environment observation network in the territory of Belarus is recording of the distant, regional, and local seismic events. Since 1966 till the present, the environmental monitoring network of the seismic stations located within the territory of Belarus recorded 60,876 seismic events in various regions of the Earth. The data obtained from strong distant, regional and local seismic events recorded by the seismic stations were analyzed, and the intensity of the seismic impact of the recorded earthquakes upon the studied territory was calculated using the N.V. Shebalin’s formula. The results of investigations performed were used to assess the seismic impact upon the territory of Belarus. A catastrophic earthquake that occurred in the Northern Sumatra western coasts in December 26, 2004, should be mentioned first among the largest earthquakes of the Earth that exerted the strongest impact upon the studied territory. An earthquake in southern Greece on January 8, 2006, and the second one in Turkey on October 23, 2011, are the events that should be mentioned among the strongest earthquakes of Europe and its adjacent areas which impact was important for the territory under study. An earthquake in Rumania on September 23, 2016, was one of the regional earthquakes that had a strong influence on the territory of Belarus. The results of the quantitative assessment of the ground shaking from earthquakes differently distant from the territory of Belarus are used for upgrading maps of the general and local seismicity, as well as for solving several other scientific and applied problems.

A review of the Sakhalin seismicity in 2014 based on the data of regional network is given. The network included four stationary and ten temporary digital seismic stations. This network was supported by ten stations of local network operating in the south of Sakhalin. Parameters of 450 seismic events, including 25 explosions, and focal mechanisms for 4 events are determined. 22 earthquakes had a macroseismic effect. The map of earthquake completeness and the map of epicenters are given. The distribution of crust and deep earthquakes on magnitude and their summarized energy for seven seismoactive areas in comparison with average parameters for 2001–2013 are presented. For each area and the region as a whole, an analysis of the seismic regime parameters in 2014 in comparison with long-term parameters is given, tangible and strong earthquakes are described. The seismicity of the Sakhalin region in 2014 can be characterized as a moderate one. Somewhat increased seismic activity was recorded in the East Sakhalin and Southeastern areas.
