Nagoya Television Tower, which is currently undergoing seismic reinforcement work, saw the completion of the process of cutting off its four pedestals from its underground concrete foundation on Oct. 23, making it look as if it is floating in the air.
The work was conducted to create space to insert seismic isolators underneath the 180-meter-high tower, which weighs 4,000 tons. The pedestals are temporarily supported by four hydraulic jacks.
The tower was completed in 1954 as the nation's first transmission tower. Due to aging, there is a danger that part of its steel frames will fracture during an earthquake measuring an upper 5 on the Japanese shindo scale, although the tower itself is unlikely to collapse.
