Seismicity, Please? 1

[RRBegin]

Does anyone know the Sds and Sd1 values for Guam and/or Midway Atoll (soil class B)? I am trying to determine the seismicity for these regions. The USGS site notes that Guam is available, but I was not able to generate a value using the building coordinates that I have.

From the Unified Facilities Criteria, Ss= 150%g, S1= 60%g

Guam or Midway?

That is Guam. You can download the document "Structural Engineering" for free from wbdg.org. Should get you close just about anywhere in the world (it's for all of our military bases and territories)

Be aware that Guam has its own engineering licensing, and the rules are rather restrictive.

I thought so (I believe that Midway is low).

I already downloaded the UFC Structural section. After I read you post, I had an "Of Course they have it!" moment and searched for the reference. I'm sure it'll prove valuable for some of the more remote locations.

Thanks for the resource.
