Fluvial archives of the Polish Carpathians bear a record of both climatic and tectonic signatures. The former consist in cyclic development of terrace covers interfingering with and/or overlain by soliluction and slopewash sediments; the latter include disturbances within strath long profiles and differentiated size of erosional downcutting. Valleys of the Outer Carpathians bear five to nine terrace steps of Pleistocene age. Most of these terraces are strath or complex-response ones; the Weichselian and Holocene steps are usually cut-and-fill landforms, except those located in the neotectonically elevated structures characterized by the presence of young straths. Long profiles of individual strath terraces frequently show divergence, convergence, upwarping, downwarping, or faulting that can be indicative of young tectonic control. Moreover, the size and rate of dissection of straths of comparable age are different in different morphotectonic units; a feature pointing to variable pattern of Quaternary uplift. Rates of river downcutting result mainly from climatic changes throughout the glacialinterglacial cycles, but their spatial differentiation appears to be influenced by tectonic factors as well. Examples based on detailed examination of deformed straths and fluvial covers in selected segments of the Polish Carpathian rivers appear to indicate Quaternary reactivation of both normal and thrust bedrock faults. The latter are mostly confined to the eastern portion of the Outer Carpathians. The Early Pleistocene, Holsteinian and Eemian stages of reactivated faulting dominated throughout the study area., Witold Zuchiewicz., and Obsahuje bibliografii
Among the first GPS geodynamics projects in Czech Republic the MORAVA network was founded in 1994 with aim to determine the positional changes at border zone between the Bohemian Massif and the Carpathians. Initial project included three successive GPS campaigns in period 1994 - 1996, but was not continued because of lack of support. It had been possible to carry out new measurements in southern part of the MORAVA network including five stations, after gap of 15 years. In the paper comparison of previous and contemporary results of epoch GPS measurements are presented, which indicate block movement tendencies at the Bohemian Massif and the Western Carpathians border, thus confirming activity of the area up to present days., Otakar Švábenský, Michal Witiska, Jan Ratiborský, Radim Blažek, Lubomil Pospíšil and Josef Weigel., and Obsahuje bibliografii
Analysis of benchmark height changes along national 1st order precise levelling lines crossing the Middle Odra Fault Zone in the Wroclaw area has been presented in this paper. The zone separates Fore-Sudetic Block from the Fore-Sudetic Monocline and is one of the main geological structures in Lower Silesia. Five national precise levelling lines cross the research area: Ząbkowice Śląskie - Wrocław, Syców - Wrocław, Karczów - Wrocław, Kawice - Wrocław oraz Krotoszyn - Wrocław. These levelling lines were measured in 1956-58, 1975-80 and 1999. Changes of benchmark heights have been presented in comparison with geological cross-sections made along the levelling lines. In the result, areas of the greatest relative vertical displacements correlated with geology and tectonics have been found., Piotr Grzempowski, Janusz Badura, Stefan Cacoń and Bogusław Przybylski., and Obsahuje bibliografii
This paper presents results of the research on tectonic activity of the marginal sudetic fault (MSF). Velocities of points obtained from processing GPS observations in the GEOSUD network and results of national precise leveling networks have been analysed. Results of 1996-2005 GPS measurements and results of measurements of selected points for the 2006-2007 period were taken considered. The velocities calculated by means of the Bernese GPS Software 5.0 were used to test hypothesis on present-day strike-slip movement activity of the marginal sudetic fault. The relationship between the calculated velocities and the length of projection onto the fault’s line was studied. The second part contains analysis of relative vertical velocities of benchmarks, making up the 1st and the 2nd class national precise leveling lines crossing the fault line, to study its vertical activity. Velocities of horizontal and vertical changes of points on both sides of the fault were compared with models described in literature., Jan Kapłon and Stefan Cacoń., and Obsahuje bibliografii
Bosnia’s seismotectonics seems to follow the Mediterranean marine regime. Earthquakes occur mostly in the outer Dinaric Alps (southern Bosnia), while the strongest earthquakes occur within the Sarajevo Fault system in southern and northwestern Bosnia. In addition to active tectonics being strong, crustal earthquakes occur often as well. Due to Bosnia’s rich hydrogeology, crustal loading such as by snow and rain, or reservoir inundation, represents the most important secondary seismogenic source in the region. Despite its exquisite and active geomorphology no comprehensive and reliable geodynamical studies exist on the region. Seismic sensors coverage is extremely poor also. One centenary analogue, and a few recently installed digital seismometers are insufficient for a region that exhibits mild-to-high seismic activity. Significant investments are needed in order for GPS, seismic and other sensor-instrumented networks to be put in place or enhanced. Technical personnel needs to be educated to enable support provide for studies that are done within broader scientific activities. Such efforts that presently seek to include Bosnia under their scope are ESF-COST Action 625, NATO Stability Pact DPPI program, and EUREF/CERGOP geophysics projects., Mensur Omerbashich and Galiba Sijarić., and Obsahuje bibliografii
