The scientists in Japan are in the process of putting together artificial tornadoes to test the houses so that the structures can be saved in an event of a disaster.
A group bearing representatives from four of the local organizations – National Institute for Land and Infrastructure Management, Building Research Institute, University of Tokyo and the Disaster Prevention Research Institute at Kyoto University, has been developing a tornado simulator.
The initiative is apparently being undertaken as numerous reports of serious structural damages have been reported in the last few years.
The simulator is 1.5 meters in diameter which is mounted on a frame that is 2.3 meters tall and 5 meters wide. It would have the ability to generate a maximum wind velocity of 15 to 20 meters per second, which is enough to reproduce an F3 size storm. As per the Japanese Fujita scale, a storm of F3 size is robust enough to uproot trees, destroy walls, dismantle steel frame structures and hurl heavy vehicles.
The senior officials in charge of the project added that such an event has never been worked upon in the country and would be of great help in cases of natural calamities. They further appended that the team would soon be building houses to test the device.
