Safe from the Tsunami
An MIT/Harvard team has developed a low-tech solution to the problem of how to build homes in tsunami-prone areas.
The team recently produced an architectural model for a Sri Lankan house that essentially would allow a powerful ocean wave to go through the house, instead of knocking it flat.
The "Tsunami Safe Houses," which will be built for about $1,200 each using materials available locally in Sri Lanka, will have four core columns made of concrete and rebar, each about 3 metres wide. Between these columns, homeowners can build walls of wood or bamboo to individualise the homes.
Engineering simulations indicate that the design will help the core and foundation of the homes to withstand water or wind force over five times greater than a traditional concrete-block Sri Lankan home.
MIT's Buddhist chaplain, Tenzin Priyadarshi, and Carlo Ratti of MIT's Senseable City Laboratory (part of the urban studies department) initiated the project. They and the MIT Buddhist Foundation, Prajnopaya, hope to begin building the homes in
