Attenuation relationships of Arias intensity for Iranian plateau using intelligent Gene Expression Programming

The earthquake is one of the natural hazards that have caused many casualties and financial losses throughout the world over the years. This has been the reason why the earthquake hazard analysis studies should be studied more seriously. Iran is also located in one of the seismically active regions...
