Let’s check to make sure that HAZUS is at least recording some shaking for your earthquake scenario. We ran Contour Maps during the analysis, so we can do the following.
Click Results—> Ground Motion or Ground Failure—> Contours or Ground Failure Maps. When the Contour Maps window appears, choose PGA Contour, and then click “Map”. This creates a colored contour layer over your study region. This layer shows us the Peak Ground Acceleration (PGA) for your earthquake scenario. For a 7.0 earthquake, we should see some pretty high PGA values, with values getting higher towards the epicenter of the quake.
If PGA values for your study region do not exceed 0.6g, then the problem is likely with the scenario itself. However, if we see reasonably high PGA values, but no damage, then the shaking from the scenario not being applied to the building inventory to damage it.
