Energy and polarization of the telluric field in correlation with seismic activity in Greece
earthquake precursor telluric field electric field polarization
2015/9/28
Many attempts have been made to disclose anomalous changes of the electromagnetic field in relation with tectonic earthquakes. We tentatively develop a new approach based on the energy and polarity of...
Evolution of magnetotelluric,total magnetic field,and VLF field parameters in Central Italy:relations to local seismic activity
Magnetotelluroc tectonomagnetism VLF waves
2015/9/28
Magnetotelluric data were collected at Collemeluccio (41.72°N, 14.37°E) in Central Italy from summer 1991 to spring 1998. Analyzed by means of tensor decomposition on the geoelectric potential and rob...
Discussion on telluric field and seismic activity in Central Greece
telluric earthquake precursors prediction
2015/9/28
Two stations were installed in the Southeastern Thessaly basin (Central Greece), recording the geomagnetic and telluric fields from 1993 to 1996. The aim was to detect long-term abnormal changes of th...
Though Ghana is far away from the major earthquake zones of the world, it is prone to earthquake disaster. Ghana has records of damaging earthquakes dating as far back as 1615. The last three major ev...
Study of the TEC data obtained from the DORIS stations in relation to seismic activity
ionosphere seismic activity total electron content
2015/9/2
Ionospheric data obtained from the DORIS system are used in this paper. The DORIS system is composed of several ground-based beacons which emit at two frequencies (400 MHz and 2 GHz) and of receivers ...
Statistical analysis of automatically detected ion density variations recorded by DEMETER and their relation to seismic activity
Satellite Earthquake interactions and probability
2015/8/24
Many examples of ionospheric perturbations observed during large seismic events were recorded by the low-altitude satellite DEMETER. However, there are also ionospheric variations without seismic acti...
Influence of seismic activity on the atmospheric electric field in Lisbon (Portugal) from 1955 to 1991
Atmospheric electric field seismic activity LAI coupling
2015/8/24
In the present study, we considered the influence of seismic activity on the atmospheric electric field recorded at Portela meteorological station (Lisbon, Portugal) for the period from 1955 to 1991. ...
A simple statistical procedure for the analysis of radon anomalies associated with seismic activity
Radon emissions Seismic precursors Seismic activity
2015/8/18
This study presents an analysis of data from various radon anomalies that were compiled by Toutain and Baubron [1999], to investigate their relationships with the earthquake parameters of magnitude an...
Some possible correlations between electro-magnetic emission and seismic activity during West Bohemia 2008 earthquake swarm
Some possible correlations electro-magnetic emission seismic activity West Bohemia 2008 earthquake swarm
2014/12/31
A potential link between electromagnetic emission (EME) and seismic activity (SA) has been the subject of scientific speculations for a long time. EME versus SA relations obtained during the 2008 eart...
Monofractal or multifractal:a case study of spatial distribution of mining-induced seismic activity
spatial distribution mining-induced seismic activity
2009/11/16
Using finite data sets and limited size of study volumes may result in significant spurious effects when estimating the scaling properties of various physical processes. These effects are examined wit...
