  • The seismic refraction reversed profiling technique has been used to investigate the topography of the last interglacial soil (paléosol S1) within the central Chinese Loess Plateau near Xifeng: variations in the depth. Discussion about the results
  • Magyarorszag szeizmikus aktivitasanak mint kornyezeti tényezoinek minositési térképe. (Qualification map of seismic activity as an environmental factor in Hungary)
  • The data of the last hundred years are used for the assessment of seismicity for the entire area of Hungary by 5 5 km. The intensity and frequency of earthquakes are combined in the seismic activity number.
  • Seismic crustal deformation in the Southern Apennines (Italy)
  • Appennino ; Earthquake ; Geophysics ; Italy ; Regional geology ; Seismicity ; Tectonics
  • With the aim of estimating the rates of seismic moment and deformation in seismic zones of southern Italy, constraints on tectonic style and kinematics data from geophysical and geologic data were integrated with the traditional constraints from
  • seismicity catalogues. Seismotectonic considerations indicate that the region can be divided into four broad crustal seismogenic volumes, of relatively homogeneous deformation: an extensional crustal volume in the western part of the Southern Apennines
  • and three crustal volumes characterized by a transcurrent regime in the eastern area. For each crustal volume, the annual seismic moment release showing the rate of the deformation was estimated by integrating magnitude-frequency relations of historical
  • The instrumental seismicity of the Abruzzo region in central Italy (1981-2003 : seismotectonic implications
  • Abruzzi ; Appennino ; Data base ; Italy ; Regional geology ; Seismic hazard ; Seismicity ; Tectonics
  • This article analyses the instrumental seismicity of the Abruzzo region in the period 1981-2003 in order to obtain a catalogue as homogeneous as possible in terms of location procedure and quality of the results. Four temporal datasets: 1981-1991
  • ; 1992-1996; 1997-1999 and 2000-2003 are analysed. The 1981-1991 dataset is taken from the CSTI catalogue. The datasets from 1992 to 2003 are relocated by integrating the recordings of the national seismic network with the recordings of the local Abruzzo
  • seismic network (operating from 1992 to 1999). Particular attention is paid to the velocity models, in order to account for the different stratigraphic/tectonic domains which characterize the Abruzzo region. The new focal mechanisms computed from the 1992
  • Seismotectonic characteristics of the Italian central Alps and implications for the seismic hazard
  • Alps (The) ; Applied geology ; Earthquake ; Fault ; Italy ; Lombardia ; Natural hazards ; Seismic hazard ; Seismicity ; Strike-slip fault ; Tectonics
  • Six vertical cross-sections have been constructed by collecting information about the surficial geology, deep crustal structures, and seismicity. A direct link between the hypocentral distribution and the tectonic structures is sometimes difficult
  • , but the analysis has given some seismotectonic suggestions. Three main seismotectonic domains remain identified : the Lombard Po plain, the Garda area, and the Alps s.s. Among these domains, the Garda area shows the highest seismicity and the earthquakes
  • are associated to the Giudicarie system and its possible interference with the Schio-Vicenza system. The general pattern of the seismogenesis is the key to defining the seismogenic zones to be used for seismic hazard assessment at regional and national scales
  • Seismic surveys integrated with geological data for in-depth investigation of Mt. Pettino active Fault area (Western L’Aquila Basin)
  • Abruzzi ; Applied geology ; Earthquake ; Fault ; Geophysics ; Italy ; Model ; Natural hazards ; Neotectonics ; Seismicity
  • Following the April 6 2009 L’Aquila earthquake, a great effort has been carried out for seismic microzonation purposes of urban areas in order to evaluate the seismic potential of the main active faults of the epicentral area. This is the case
  • of the active Mt. Pettino master extensional fault (hereafter PEF) which controls the tectono-sedimentary evolution of western L’Aquila Basin. The investigations were mainly based on a seismic reflection profile orthogonal to the fault strike in its hangingwall
  • . The seismic profile was interpreted by comparison with the geological outcropping data and the stratigraphic analysis of numerous boreholes, several of which reached the pre-Quaternary substratum. The main goals were double : (i) to improve the integrated
  • geological-geophysical subsurface model for the evaluation of the local seismic amplification and (ii) to estimate the PEF seismic hazard through the study of the sedimentary infill evolution and the tectonic subsidence of the PEF hangingwall which were
  • strictly interrelated with the PEF seismic history. - (NF)
  • Investigation of coupling between surface processes and induced flow in the lower continental crust as a cause of intraplate seismicity
  • California ; Earth surface processes ; Erosion rate ; Global change ; Human impact ; Japan ; Natural hazards ; Plate tectonics ; Seismicity ; South Carolina ; United States of America
  • On the basis of the rheological knowledge gained, it is suggested that intraplate seismicity can also be caused by coupling between surface processes and flow in the lower continental crust. This view is shown to be a natural consequence
  • of the modern idea that isostatic equilibrium is maintained by flow in the weak lower crust in response to erosion and sedimentation. It is supported by a general correlation between the vigour of surface processes and rates of intraplate seismicity
  • , and by instances of seasonal seismicity that correlates with seasonal climate. Human interference in the environment can affect surface loading and can cause increased erosion rates.

  • A comprehensive geotechnical survey for the offshore extention of Zeebrugge harbour illustrates some possibilities and limitations of seismic profiling in Belgian offshore areas and proves a striking example of its successful integration
