Seismic data:

Spectral response acceleration % of g
.2 sec 105
1 sec 34

Assuming you are in a jurisdiction that uses it, you need to apply sections 13.3 to 13.5 of ASCE 7-10. If that is beyond you then you need to contract with a licensed structural engineer. Please note this assumes that the wall is absolutely non-structural.
