I want to dig out a little pond on my land and place a ship in it and would live in the ship. Would be such house earthquake resistant?

Not a bad idea and not the first to think of it.

I have been trying to visualize a way to survive mega quakes. So far:


I am thinking of a relatively shallow dam with a raft with a dwelling made from numerous truck tubes. The raft could be set in a small shallow dam, dug and filled for this purpose. The dam water to be only knee deep so one could walk to and from shelter. In any case the dammed water would be a useful asset. This would also absorb any smaller jolts, and would be constant proof and reassurance that the buoyancy was OK. The dam need only be slightly bigger than the raft to do this job. Thus someone one a farm with a couple of dozen tires would have all that was needed.


The raft is secured by four deep steel piles via nylon "mooring" lines, say 100 meters long to all cardinal points. Nylon has great strength and some stretch and a steel wire trace could be placed at the near max stretch of nylon mooring lines to back them up. This would cover both lateral and vertical earthquakes. I would bring the four steel traces to a center ring and to that attach personal safety lines as yacht sailors use. Care on getting the steel piles deep and cemented most important.


* While a survival trench certainly will give more wind and fire type protection it will be a hell place to be in a huge jolt ( before, during and after ). The Chinese build huge sailing junks without an unstayed mast, in a Typhoon the mast gives and the vessel survives. In a tethered raft the shocks will be absorbed much the same, it could still have a heavy duty steel cover, and does not have the worry of getting out of a buried trench, and always getting air in. I would not like to rely on a dugout if there was also a chance of inundation's, so the floating "capsule" is double survival chance.

* The most likely worst effect would be to get a shower from splashing water occasionally. A heavy pair of bolt cutters and a knife would allow one to cut the tethers if the water level went up beyond the allowed lift in the tethers. Should the inundation cause the raft to rise on the four moorings, the center tether should be cut freeing 3 moorings, and not setting the raft free just yet. The fourth mooring would hold the raft as an anchor point and allow for even further rises yet remain tethered. If flooding continued even higher then cut the fourth tether and take your chance on a wild ride to who knows where, but still a very high survival possibility. The worlds history and literature has many stories of people surviving clinging to various rafts, etc.

* More smaller car tubes could be put on the inner walls as cushion shock absorbers for further back up. If the dam became exhausted the system would still work, this time with truck tires say at the four extremes of the raft acting as skids and shock absorbers. If all this was on a clay type base abrasion of tires with lateral movement would be minimal.

* The shelter could have a tent like cover. An additional benefit of floating on a dam would be immediate access to water in a fire storm. For drinking water, simple water boiling and carbon filtration would provide perfectly suitable water, if the water was cloudy, some alum sulfate to flocculate (cause the particles to drop out of suspension ) could be added prior to boiling. Provided waste water was sent to a separate trench and the dam could easily be lined with a plastic liner for low cost, then there would be no contamination.

* The whole thing would be easy to build and cheap. Most tire repair places are happy to give away old tires and even quite repairable tubes. The truck tires would either have tubes inflated or better still be foam filled with two anchor plates to hold and protect the foam there (much as is done to make mooring buoys).

Anyway, we have to start thinking about concepts that might just work. Might not be the Hilton but it would give a fighting chance.

Hey, sounds like a plan that could work in the case of "small" quakes.

What happens if the ground moves by more than the depth of the dam? You get really wet?

A cool idea though.
