Macroseismic intensity attenuation in western China

Journal of Seismology, 2021
Macroseismic intensity data play an important role in seismic hazard analysis and in developing reliable earthquake loss models. This paper adopts an ellipse model to predict the macroseismic intensity attenuation in both the long-axis and the short-axis directions based on 136 earthquakes recorded throughout western China during 1970–2012.

Macroseismic intensity attenuation in Iran

Earthquake Engineering and Engineering Vibration, 2018
Macroseismic intensity data plays an important role in the process of seismic hazard analysis as well in developing of reliable earthquake loss models. This paper presents a physical-based model to predict macroseismic intensity attenuation based on 560 intensity data obtained in Iran in the time period 1975–2013.

On the Observed Intensity Filtering in the Anisotropic Distribution Modelling of Macroseismic Intensity

Pure and Applied Geophysics, 2005
The anisotropic modelling of intensity distribution, affected by the construction of macroseismic planes, allows an analysis of the influence of each point of observed intensity on the analytical determination of epicenter and of the principal attenuation directions.

On an anisotropic attenuation law of the macroseismic intensity

Natural Hazards, 1995
An anisotropic attenuation law of the macroseismic intensity has been deduced, congruent with an anisotropic modelling of macroseismic fields. The results, obtained by analysing a set of earthquakes in Eastern Sicily and Southern Calabria, show a greater adaptability to the observed data as compared with those deduced using isotropic attenuation laws ...

On the Intensity Virtual Area Characterization in the Intensity Distribution Modelling by Macroseismic Planes

Pure and Applied Geophysics, 2005
A procedure is proposed for the reconfiguration of the macroseismic planes relative to earthquakes that, being characterized by a reduced number of points of observed intensity due to a lack of information, or having the epicenter very close to the coastline, are characterized by an incomplete distribution of observed intensity levels.

The determination of the epicentre by a vectorial modelling of macroseismic intensity distribution

Natural Hazards, 1996
A vectorial modelling of observed macroseismic intensity aimed at the analytical determination of the epicentre is proposed here. The methodology is based on the determination of a plane system of vectors which characterises the macroseismic intensity distribution.
