Turbo,

"Superadobe Technology is designed by Nader Khalili, engineering by P. .J. Vittore, models of which have been constructed and tested for the City of Hesperia, California, Building and Safety Department, in consultation with I.C.B.O. (International Conference of Building Officials), in the forms of arches, vaults, and domes between 1993 and 1996. These successfully passed the California required codes for the models."

Actually, adobe-type domes are one of the safer designs for earthquake-prone areas. Many domed buildings in Iran & Iraq have survived earthquakes for over 100 years, including recent quakes that demolished modern buildings. (Please note that I'm not including geodesic domes here, as I know nothing about them.)
