Correlation analysis technique revealing ionospheric precursors of earthquakes
correlation analysis technique ionospheric precursors earthquakes
2009/12/14
In this paper we focus on the variability of electron concentration in the ionosphere measured by ground based ionosondes and GPS receivers around the time of strong earthquakes. It has been detected ...
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...
VLF-LF radio signals collected at Bari (South Italy): a preliminary analysis on signal anomalies associated with earthquakes
VLF-LF radio signals a preliminary analysis signal anomalies earthquakes
2009/12/14
At the beginning of 2002 an OmniPAL receiver was put into operation at the Department of Physics of Bari University (Southern Italy). The electric field strength of five VLF-LF signals transmitted fro...
Analysis of the ULF electromagnetic emission related to seismic activity, Teoloyucan geomagnetic station, 1998-2001
the ULF electromagnetic emission seismic activity Teoloyucan geomagnetic station
2009/12/14
Results of ULF geomagnetic measurements at station Teoloyucan (Central Mexico, 99.11'35.735''W, 19.44'45.100''N, 2280m height) in relation to seismic activity in the period 1998-2001 and their analysi...
Principal component analysis of geoelectrical signals measured in the seismically active area of Basilicata Region (southern Italy)
principal component analysis geoelectrical signals the seismically active area Basilicata Region
2009/12/14
Geoelectrical fluctuations are the end product of several geophysical phenomena. In particular geoelectrical signals measured in seismically active areas can be attributed to stress and strain changes...
Rockfall travel distance analysis by using empirical models (Solà d'Andorra la Vella, Central Pyrenees)
Rockfall travel distance analysis empirical models
2009/12/31
In total, data from twenty small rockfalls have been gathered which reveal an amount of a hundred individual fallen rock blocks. The data acquired has been used to check the reliability of the main em...
Time independent seismic hazard analysis of Greece deduced from Bayesian statistics
Time independent seismic hazard analysis Greece Bayesian statistics
2009/12/11
A Bayesian statistics approach is applied in the seismogenic sources of Greece and the surrounding area in order to assess seismic hazard, assuming that the earthquake occurrence follows the Poisson p...
Fractal analysis of the ULF geomagnetic data obtained at Izu Peninsula,Japan in relation to the nearby earthquake swarm of June–August 2000
Fractal analysis ULF geomagnetic data Izu Peninsula nearby earthquake swarm
2009/12/11
In our recent papers we applied fractal methods to extract the earthquake precursory signatures from scaling characteristics of the ULF geomagnetic data, obtained in a seismic active region of Guam Is...
RST analysis of MSG-SEVIRI TIR radiances at the time of the Abruzzo 6 April 2009 earthquake
RST analysis MSG-SEVIRI TIR radiances the Abruzzo 6 April 2009 earthquake
2009/12/31
The general RST approach has been proposed in order to discriminate normal (i.e. related to the change of natural factor and/or observation conditions) TIR signal fluctuations from anomalous signal tr...
Analysis of natural neutron flux in a seismically active zone
natural neutron flux a seismically active zone
2009/12/10
In a seismically active zone in the near Almaty area (Kazakhstan) since 1996 observations of variations of a natural neutron flux have been conducted. Sometimes the neutron flux rises sharply within t...
Tsunami vulnerability assessment and its implications for coastal hazard analysis and disaster management planning, Gulf of Corinth, Greece
Tsunami vulnerability assessment coastal hazard analysis disaster management planning
2009/12/10
We apply a new tsunami vulnerability assessment method to two coastal villages in the Gulf of Corinth, Greece using the 7th February 1963 tsunami as a worse case scenario. In Akoli, 46.5% of all build...
A historical analysis of hazardous events in the Alps – the case of Hindelang (Bavaria, Germany)
A historical analysis hazardous events the Alps the case of Hindelang
2009/12/10
A historical analysis of natural hazards for the Hindelang area in the Bavarian Alps is done by researching and assessing data from different archives. The focus is on an evaluation of historical haza...
