In 1992 seismogenic nodes prone for earthquakes<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mn>6.5</mml:mn><mml:mo>+</mml:mo></mml:mrow></mml:math>have been recognized the Himalayan arc using pattern recognition approach. Since then four earthquakes of target magnitudes occurred in region. The paper discusses correlation events region after with previously defined as having potential occurrence...

Information about potential earthquake sources is a key issue for seismic hazard assessment. This study presents the application of phenomenological approach based on pattern recognition to determine possible locations strong earthquakes in Bulgarian region. The technique assumes origin morphostructural nodes formed around intersections lineaments identified by zoning. For territory Bulgaria and neighbouring regions, 178 were defined this work. CORA-3 algorithm 59 seismogenic analysing set...

On February 6, 2023, two devastating earthquakes struck southern central Turkey, nin hours apart. The ground shaking from these even swept over a significant part of northwestern Syria. In this paper, we consider the locations epicenters earthquake relative to prediction М ≥ 6.5 in Anatolia and adjacent regions, which was made 1973 by I.M. Gelfand, V.I. Keilis-Borok their colleagues using Kora-3 pattern recognition algorithm based on morphostructural zoning data. We also present results...

The principle of modification mechanical properties thin-film membrane structures arbitrary shape by non-contact method was proposed, realized and explained for the first time. idea tested on an aluminum formed magnetron a silicon substrate. external influence means cyclic loading in form discharge supply excess air pressure to membrane. As result repeated impacts, physical materials (grain size roughness) (internal stresses critical overpressure) are changed. Changing magnitude residual...

The Altai–Sayan mountain-folded belt is analyzed with the purpose of (1) revealing peculiarities localization large-scale polymetallic mineralization in lineament-block structure region and (2) determining geophysical geomorphic locations these deposits using Cora-3 pattern recognition algorithm. determined morphostructural zoning. A spatial correlation between large superlarge nodes revealed. Based on this correlation, a dichotomy problem solved, which to divide entire set into two...

Information on the areas prone to strongest earthquakes in a region is very important for knowledgeable seismic hazard and risk assessment. We consider central part of Alpine-Himalayan Belt (Caucasus–Kopet Dagh-Alburz) recognition seismogenic nodes capable M7+ earthquakes. The formed around intersections fault zones are viewed as objects which have been described by common set geologic, geomorphologic geophysical parameters. 150 out 510 ones delineated Caucasus Kopet Dagh- Alburz were...

Summary Information on potential earthquake sources is a key issue for seismic hazard assessment. The work presents an application of the phenomenological approach identifying possible locations strong earthquakes in Bulgarian region. methodology hypothesizes nucleation at morphostructural nodes, forming intersections lineaments, which are detected by zoning. Based wide set geophysical and geological data characterizing nodes pattern recognition algorithm Cora- 3 pinpointed capable M6+ Most...

The Bulgarian Region is located in the Southeastern Europe, with not so frequent recent seismicity. Several strong seismic events beginning of XX century evidenced capability main faults to accumulate significant energy. In this study, we investigate seismicity region using numerical block-and-fault dynamics (BAFD) model lithosphere and morphostructural zoning outlines major crustal blocks, external driving motions are prescribed GPS data. We performed preliminary test for simplified block...
