I recently had a representative from the National Oceanic and Atmospheric Administration (NOAA), an agency of the US Department of Commerce that conducts environmental research, contact me. The NOAA wanted to know if a Monolithic Dome could be built that would survive a 100 foot tsunami. My answer was an absolute Yes with this provision: a rock that I could anchor the dome to.

I neglected to mention that there is not much sense in sealing the shell-foundation cold joint if the floor of the dome is not also designed to withstand hydrostatic pressure. Otherwise, the floor might leak or break apart. Here is what was left of the ground-floor of Dome of a Home after a hurricane raised the water level higher than the floor
