seismic loads on buried structures

I live and work in a low seismic zone, but i'm involved in designing a product that may be used in active seismic regions (e.g., California). I can find very few good references on seismic loadings for buried structures. I realize that loadings will be highly dependant on soil conditions at each specific site, but can anyone give me general directions on criteria for design loads?

Could a static analysis be used or will dynamic analysis be required? What acceleration coefficient would be appropriate?

Any help would be appreciated. Thanks.

The soil characteristics are very well dealt in International Building Code 2000. The acceleration coefficient is calculated based on soil profile (Table 1615.1.1 page 350 of IBC 2000).

Whether you have to do static or dynamic analysis depends upon the the type and importance of the structure you are working with.
