چکیده:

This paper presents predictive relationship for Arias Intensity derived from 22 strong-motion records generated by 19 earthquakes in Alborz and Central-Iran. The proposed attenuation relationship for Arias Intensity is presented in the following form:

[Fromula]

Where Ia is Arias Intensity in m/sec, M is moment magnitude, R is focal distance in km, and P is 0 for 50- percentile values, and 1 for 84-percentiles.
