Seismic scenarios and assessment of intensity: some criteria for the use of the MCS scale
macroseismic scale macroseismic intensity MCS scale
2015/9/30
The macroseismic scale used for the classification of the more than 33100 seismic effects of the Catalogue of Strong Italian Earthquakes (CFTI3) is the Mercalli Cancani Sieberg (MCS). As in all scales...
Reducing the subjectivity of intensity estimates: the Fuzzy Set approach
macroseismic intensity fuzzy sets Mugello Garfagnana
2015/9/30
We describe a method for the encoding and the computer analysis of the macroseismic effects deduced from historical sources allowing the complete formalization of the process of seismic intensity asse...
Bayesian analysisof a probability distribution for local intensity attenuation
Beta distribution binomial distribution power law random intensity decay validation
2015/9/15
Intensity attenuation and its variation as a function of the distance and earthquake size is still a critical issue in evaluating seismic hazard. We present a method that allows us to incorporate addi...
The investigation of the records of past earthquakes in Europe and in other countries of the world produced in recent years a large amount of information, such as historical seismicity studies, earthq...
The attenuation of seismic intensity in the Etna region and comparison with other Italian volcanic districts
macroseismic intensity attenuation Mt. Etna Italian volcanic areas
2015/9/8
A detailed analysis of the intensity attenuation in the Etna and other Italian volcanic districts, was performed using the most recent and complete intensity datasets. Attenuation laws were derived th...
A new dataset and empirical relationships between magnitude/intensity and epicentral distance for liquefaction in central-eastern Sicily

Strong earthquakes can trigger several phenomena inducing soil deformation, such as liquefaction, ground fracturing and landslides, which can often cause more damage than the seismic shaking itself. A...
Effects of surface irregularities on intensity data from laser scanning: an experimental approach
Terrestrial Laser Scanner Intensity Incidence Angle
2015/9/1
The results of an experiment carried out with the aim to investigate the role of surface irregularities on the intensity data provided by a terrestrial laser scanner (TLS) survey are reported here. De...
The intensity attenuation of Colfiorito and other strong earthquakes:the viewpoint of forecasters and data gatherers
Attenuation Forecast Macroseismic intensity Seismic scenario Validation criteria
2015/9/1
This article has been originated by thoughts on previous analyses related to the proba- bilistic treatment of the macroseismic attenuation, from which it turns out that in Italian territory the intens...
