Floating homes

Japan is a country that experiences frequent earthquakes, and as a result, they have been developing various technologies to mitigate the damage caused by earthquakes. One of these technologies is the "earthquake-resistant house," which is designed to rise above ground during an earthquake to protect the home and its inhabitants.

The technology, known as the "Mammoth" system, was developed by the Japanese construction company, Air Danshin Systems Inc. The system uses hydraulic jacks to lift the house off the ground and then supports it with a network of steel legs, which are designed to absorb the shock of an earthquake.

When an earthquake occurs, sensors detect the seismic activity and activate the hydraulic jacks, lifting the house up to 3 meters (9.8 feet) off the ground in just a few seconds. The house is held in place by the steel legs, which are anchored to a concrete foundation.

The Mammoth system has been tested extensively and has been shown to be effective in reducing the damage caused by earthquakes. In addition, the system has been designed to be affordable, with estimates suggesting that the cost of retrofitting an existing home with the system would be around $70,000.

The technology has already been implemented in a few homes in Japan, and it is expected to become more widespread in the future. The earthquake-resistant house is just one example of the innovative technologies being developed in Japan to protect against earthquakes and other natural disasters.
