High-density macroseismic survey in urban areas. Part 1: proposal for a methodology and its application to the city of Rome
urban area high-density macroseismic survey questionnaire urban geology Rome
2015/10/8
The aim of this research is to provide an original contribution to the investigation of local macroseismic variations in urban areas by means of questionnaire surveys. In this paper, we propose a meth...
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...

2015/9/29
Magnetic observations made onshore the Italian Peninsula, and across the adjacent seas, have been compiled in a new digital database that provides the first complete regional scale view of the crustal...
Short time scale laws in self-potentialsignals from two different seismically active Mediterranean areas(the Southern Apennine chainand Crete Island)
self-potential earthquake prediction structural analysis anomalous diffusion
2015/9/28
Self-potential time series are investigated to characterise self-potential time scales. The data analysed were recorded in stations located in two active seismic areas of the Mediterranean region, the...
Robust satellite techniques for remote sensing of seismically active areas
Earthquake satellite remote sensing thermal IR anomaly robust satellite techniques seismogenic areas monitoring
2015/9/28
Several satellite techniques have been recently proposed to remotely map seismically active zones and to monitor geophysical phenomena possibly associated with earthquakes. Even if questionable in ter...
Earth modeling and estimation of the local seismic ground motion due to site geology in complex volcanoclastic areas
dynamic amplification factor seismic tomography pyroclastic rocks finite element method
2015/9/25
Volcanic areas often show complex behaviour as far as seismic waves propagation and seismic motion at surface are concerned. In fact, the finite lateral extent of surface layers such as lava flows, bl...
Improved techniques in data analysis and interpretation of potential fields:examples of application in volcanic and seismically active areas
