Spatial Distribution of Seismicity: Relationships with Geomagnetic Z-Component in Geocentric Solar Magnetospheric Coordinate System
Earthquake Occurrence Earthquake Magnitude
2013/3/11
For 173477 epicenters of earthquakes with М ≥ 4.5, which occurred at the globe in 1973-2010, the geomagnetic Z-component in Geocentric Solar Magnetospheric (GSM) coordinate system were evaluated for t...
Numerical and Geophysical Tools Applied for the Prediction of Mine Induced Seismicity in French Coalmines
Induced Seismicity Numerical Modelling Rockburst Mining Design
2013/3/11
The determination of the influence of mining works and the induced seismicity is essentially obtained, separately from in-situ observations and seismic analysis, field measurements (particularly surfa...
Seismicity and Geologic Structures Indubitable in Wadi Hagul, North Eastern Desert, Egypt
Eastern Desert Wadi Hagul Remote Sensing GIS Seismic Activity
2013/3/6
Paleo and recent earthquakes have been recorded in Wadi Hagul area and its environs, which have left behind geologic structures of deformation preserved in exposed sedimentary rocks. To evaluate such ...
Up-To-Date Geodynamics and Seismicity of Central Asia
Lithosphere Plates Seismicity Active Faults Transit Zone
2013/3/6
The analysis of the seismicity in central Asia shows its distribution within a “triangle” of maximal inner-continental seismic activity, which is situated between south edge of the Lake Baikal and the...
Seismicity anomalies prior to the 13 December 2008,Ms=5.7 earthquake in Central Greece
Seismicity anomalies Ms=5.7 earthquake Central Greece
2009/12/16
This investigation has applied a recent methodology to identify seismic quiescence and seismic acceleration, prior to the occurrence of the 13 December 2008, Ms=5.7 earthquake in Central Greece. Anoma...
Seismicity anomalies prior to 8 June 2008,Mw=6.4 earthquake in Western Greece
Seismicity anomalies Mw=6.4 earthquake Western Greece
2009/12/16
The epicentral area of the Mw=6.4, 8 June 2008 main shock in northwestern Peloponesus, Western Greece, had been forecasted as a candidate for the occurrence of a strong earthquake by independent scien...
Seismogenic zonation and seismic hazard estimates in a Southern Italy area (Northern Apulia) characterised by moderate seismicity rates
Seismogenic zonation seismic hazard estimates Southern Italy area moderate seismicity rates
2009/12/16
The northernmost part of Apulia, in Southern Italy, is an emerged portion of the Adriatic plate, which in past centuries was hit by at least three disastrous earthquakes and at present is occasionally...
Probabilistic seismic hazard maps from seismicity patterns analysis:the Iberian Peninsula case
Probabilistic seismic hazard maps seismicity patterns analysis Iberian Peninsula case
2009/12/14
Earthquake prediction is a main topic in Seismology. Here, the goal is to know the correlation between the seismicity at a certain place at a given time with the seismicity at the same place, but at a...
Information entropy analysis of seismicity of Umbria-Marche region (Central Italy)
Information entropy seismicity Umbria-Marche region
2009/12/14
We investigated by means of nonlinear tools the temporal distribution of 1983-2003 seismicity of the Umbria-Marche region, Central Italy, that was struck by a strong event (M=5.8) on 26 September 1997...
Dynamics of multifractal and correlation characteristics of the spatio-temporal distribution of regional seismicity before the strong earthquakes
multifractal and correlation characteristics spatio-temporal distribution regional seismicity
2009/12/11
Investigations of the distribution of regional seismicity and the results of numerical simulations of the seismic process show the increase of inhomogenity in spatio-temporal distribution of the seism...
Distributed power-law seismicity changes and crustal deformation in the SW Hellenic ARC
power-law seismicity changes crustal deformation SW Hellenic ARC
2009/12/11
A region of definite accelerating seismic release rates has been identified at the SW Hellenic Arc and Trench system, of Peloponnesus, and to the south-west of the island of Kythera (Greece). The iden...
Scaling behaviour in temporal fluctuations of crustal seismicity in Taiwan
Scaling behaviour temporal fluctuations crustal seismicity Taiwan
2009/12/31
The crustal seismicity of Taiwan was investigated by means of the Allan Factor analysis and Count-based Periodogram, which allow to identify scaling behaviour in point processes and to quantify their ...
The pecularities of shear crack pre-rupture evolution and distribution of seismicity before strong earthquakes
shear crack pre-rupture evolution seismicity strong earthquakes
2009/12/9
Several methods are presently suggested for investigating pre-earthquake evolution of the regions of high tectonic activity based on analysis of the seismicity spatial distribution. Some precursor sig...

2009/12/9
We test the hypothesis that critical point dynamics precedes strong earthquakes in a region surrounding the future hypocenter. Therefore, we search systematically for regions obeying critical point dy...
