Until then, maybe you can cover it with a tarp or something

Ride out the next tsunami in this clever capsule

In the 50s and 60s, people built bomb shelters in their back yards and basements in case the Russkies dropped the big one. I guess the current scare is tsunamis, but at least this device has the advantage of being portable. If you move to a new house, you can just bring it with you!

These "survival capsules" are designed to be hardened shelters that float in case of a tsunami or catastrophic flood. Be sure to pack the anti-seasickness pills!
