Hi,

I’m having problem with the calculation of the logic tree. I’m trying to do an analysis with this 4 GMPE:

-          Bindi 2011, with a weight of 33 (probability 0.33)

-          Akkar 2014, with a weight of 33 (probability 0.33)

-          Boore 2014, with a weight of 17 (probability 0.17)

-          Cauzzi 2015, with a weight of 17 (probability 0.17)

The results of my logic tree are lower than all the other single GMPE results in terms of exceedance probability. Is this any reason for these results? I was expecting a result between the single GMPE.

 

I have a second question. How works the option add models?

 

Thanks
