The external magnetic sources over the polar caps - Feasible modelling unrealistic expectations
magnetospheric model plasma cavity Hamilton's principle substorm auroral oval Svalgaard vortex ? aurora luminosity curve electric current electric field plasma drift trapped particles
2015/10/8
No average status can be defined for the sources of the external magnetic field over the polar caps, no index can provide with any such model, the observation of no single quantity or parameter can gi...
Towards new research strategies: silent seismogenic areas or silent sources?
Historical seismology paleoseismology Apennines
2015/9/30
Some earthquakes, particularly the strongest ones, can re-occur within hundreds or thousands of years. Therefore, the areas whose "seismic history" seems to be totally lacking in information are indee...
From earthquake intensities to earthquake sources: extending the contribution of historical seismology to seismotectonic studies
Historical earthquakes source orientation seismotectonics seismic intensity
2015/9/30
The epicentral locations and magnitudes of the events reported in the Catalogue of Strong Italian Earthquakes are obtained from intensity data through a standardized and established algorithm. However...
Evidence of historical seismicity and volcanism in the Armenian Highland (from Armenian and other sources)
historical seismicity volcanism catalogue
2015/9/14
This work presents a summary on the development of studies of historical earthquakes in Armenia and adjacent parts of Turkey and Iran. Since ancient times, this region has been an arena where active g...
Implications of some early Jewish sources for estimates of earthquake hazardin the Holy Land
historical seismology paleoseismology Dead Sea Rift
2015/9/14
For the past two millennia the Holy Land was under the yoke of successive invaders and oppressors, not a fertile ground for growth of historiographic traditions. Consequently, earthquake cataloguers h...
The study of local sources of ULF geoelectric signals with steep fronts
geoelectricity earthquakes prediction method VAN
2015/9/14
The method for recognition and monitoring of ULF electrotelluric signals with steep fronts is presented. The method is based on the multicomponent measurements of the geoelectric field and recognition...
Seven missing damaging earthquakes in Upper Valtiberina (Central Italy) in 16th-18th century: research strategies and historical sources
missing earthquakes historical seismology Italian earthquake catalogues Upper Valtiberina
2015/9/8
The Italian earthquake catalogue is considered to be fairly complete starting from the 17th century and for classes
of earthquakes of magnitude greater than 5.5. However, dedicated historical researc...
