Abstract. Peak ground velocity (PGV) has many applications in engineering seismology and earthquake engineering but there are relatively few prediction equations for this parameter in comparison with the large numbers of equations for estimating peak ground acceleration [1, 2]. The purpose of this study is to derive the attenuation relationships for larger horizontal component () and geometric mean horizontal component () of PGV for Iran. In the present paper new attenuation relations are proposed based on 484 strong motion recordings from earthquakes in Iran. The prediction equations were derived by regression method. The data set used consists of records with magnitudes 4.57.4 and epicentral distances
1 km
150 km. The theoretical-empirical Relationships obtained in this study is one of the first Studies in PGV field for Iran and is comparable with the world famous relations. Comparisons with other predictive relations from other regions are also carried out.

Keywords: attenuation relationships, PGVH, ground motion, PGV for Iran.
