1 UPStrat-MAFA 3rd General Meeting Selfoss, Iceland, 23-26 July 2013 AREA 3 Modifications to EXSIM code to allow for multiple site amplifications curves and random variation of source parameters Horst Langer, INGV-Catania, Italy Mariano Garcia-Fernandez, IGEO (CSIC,UCM), Spain

2 UPStrat-MAFA 3rd General Meeting Selfoss, Iceland, 23-26 July 2013 AREA 3 EXSIM – Modifications 1)Two shear wave velocities, one related to the source volume, one used for geometrical spreading 2)Calculation of Housner Intensity 3)Magnitude and stress parameter can be varied randomly 4)Site amplification can be specified for each indivual site (instead of a generic correction valid for all sites in the original version) 5)Radiation pattern and shear wave velocity can be adjusted for each single site 6)New Output files *stat.out and *resp.out (report min and max values of simulated GM parameters and Housner Intensity, together with distances and cartesian coordinates of each site. The *resp.out* reports full response spectra)
