CA Seismic Source Data

[azcats]

I'm working on a project in SoCal, Ontario to be exact. Can anyone here help me find the seismic source data for the specific site? IE, the distance to type A or type B faults.

I haven't been able to get my hands on a map and there isn't a Geotech on board yet. The client is looking for some preliminary info for budgets and I'm trying to help them out.

I'll have to take a guess at the soil profile, but I'd rather be guessing at one item rather than two...or three.

Here is a map of the site.

If the link doesn't work, the site is Cedar Street at Proforma Avenue in Ontario, CA.

I really appreciate any help.

Thanks.

John

Without having a geotechnical engineer on board, you can still assume within 2km of a type B fault and a type Sd soil for your preliminary design. Of course when the information becomes available, you still need to verify your initial assumptions.

For $55, you can purchase the seismic maps from the ICC Store:

Without my book next to me I want to say that you are just more than 10km from an A fault and more than 5km from a B fault giving you an Na of 1.0 - but buying the seismic maps would be a better idea than guessing. The cost of the maps is minimal so it won't really hurt if you don't get the project.
