Results from a detailed analysis of the French macroseismic database SIRENE96 show that geomechanical site effects (i.e. site effects due to superficial geology) can be statistically detected and quantified from macroseismic data. Our results are used to derive a predictive map of potential site effects in France and to check if site effects induce a ...

Macroseismic Intensity Assessment Method for Web Questionnaires
Seismological Research Letters, 2015Online Material: Tables of questions and answers of the macroseismic questionnaire, score matrices, and a figure showing a macroseismic field example. Macroseismic investigation with data collected through web‐based questionnaires is today routinely applied by most important seismological institutions, such as the U.S.

New macroseismic intensity predictive models for Turkey
Acta Geophysica, 2019In this study, we propose new attenuation relations for use in possible future macroseismicity-based analyses for Turkey. The most significant difference of the new relationships is that they are specifically designed for use in the full extent of Turkey.

Anisotropic attenuation of the macroseismic intensity
2019Macroseismic intensity is a measure of the size of an earthquake in terms of the damages caused to the anthropic and natural environment; it is an ordinal quantity expressed through the twelve degrees of the macroseismic scale. The set of intensity values recorded in the sites around the epicenter constitutes the macroseismic field of the event, that ...

Macroseismic intensity versus epicentral distance: the case of Central Italy
Tectonophysics, 1991This paper refers to the attenuation of macroseismic intensity with epicentral distance. A new attenuation law is discussed, with particular reference to Italian conditions. The new formula shows a much better fit compared to traditional attenuation laws.

EMS and MCS macroseismic intensities assessed in Italy are equivalent?
2020<p>The most of intensity assessments provided by the large (more than 100000 intensity observations) Italian macroseismic database (DBMI15) were made using the traditional Mercalli-Cancani-Sieberg (MCS) scale but in most recent macroseismic surveys in Italy even the European Macroseismic Scale (EMS) scale was used by some ...

GeoInt: the first macroseismic intensity database for the Republic of Georgia
Journal of Seismology, 2018Our work is intended to present the new macroseismic intensity database for the Republic of Georgia—hereby named GeoInt—which includes earthquakes from the historical (from 1250 B.C. onwards) to the instrumental era. Such database is composed of 111 selected earthquakes and related 3944 intensity data points (IDPs) for 1509 different localities ...

Pure and Applied Geophysics, 2005
An anisotropic attenuation law, based on an anisotropic characterization of intensity distribution for seismogenic zones, is proposed. This approach, that distinguishes itself for its consistency to the observed data, initially reconfigured by filtering procedures, is particularly suitable for seismic hazard evaluation.

Assessment of macroseismic intensity in the Nile basin, Egypt
Journal of Seismology, 2017This work intends to assess deterministic seismic hazard and risk analysis in terms of the maximum expected intensity map of the Egyptian Nile basin sector. Seismic source zone model of Egypt was delineated based on updated compatible earthquake catalog in 2015, focal mechanisms, and the common tectonic elements.

Influence of Observation Floor and Building Height on Macroseismic Intensity
Seismological Research Letters, 2012Online material : Distribution of data as a function of MCS intensity and distance; additional information about the intensity residuals and the applied statistical tests. It is well known that perception of transitory effects is quite dependent on an observer’s location.
