RESUMO
Macroseismic data of earthquakes felt in Israel and also recorded instrumentally are analyzed. The analysis yields the following empirical relations: î=0.2 + 1.6M - 2.5log(r)-0.003r, o=0.7, r²=R²+15², M=2.5+0.51, o=1.3, Ie= 1.6M-3.5, o=0.5, M=0.3+2.1 log D, O=0.4, where M is the local magnitude, î is the expected seismic intensity (MSK-scale), R is the epicentral distance Ie is the average seismic intensity in the focal area (within 20 km) and D is the radius of the areain which seismic intensities of grade III or more were observed o is the one standard deviation. Using macroseismic observations in Israel folloding distant-earthquakes and by using the empirical attenuation function (see above). The results indicate a poor correlation between the intensity response of a site and its geological and geotechnical properties (AU)
