6日韩国首尔的电器电子商城Techno Mart突然上下震动10分钟左右，专家经调查后认为，这次震动起因是大楼里有一个健身中心，参加健身项目的学员集体跳动引起震动。

South Korean experts said Tuesday they believe a vigorous（有力的） gym exercise session caused a high-rise building in the capital to shake for 10 minutes this month, prompting hundreds to flee in panic.

They said tests showed that oscillations（振动） created by a group of Tae Bo practitioners1 on the 12th floor of the 39-story TechnoMart mall building apparently2 resonated（共鸣，共振） through the structure.

Tae Bo is an aerobic3 exercise routine that involves performing the motions of boxing and martial4 arts such as Taekwondo at a rapid pace.

Professor Chung Lan of Danguk University in Yongin City near Seoul linked the incident to a physics principle under which catastrophic failures can occur when the vibration5 of a structure is matched by another source.

He told a radio programme that the building, constructed from iron girders（大梁） and cement, had a characteristic vibration frequency which was "in phase" with the synchronised movements of the Tae Bo practitioners.

Chung and six others re-created the scenario6 which caused the panic on July 5 -- with a group of 17 middle-aged7 people working out to the tune8 of a pop song, "The Power" by German group Snap -- and said the building shook in a similar way.

On the first occasion hundreds fled the building as it shook for about 10 minutes. The Gwangjin district government ordered the mall closed but reopened it after experts said it was structurally9 sound.

The gym remains10 off-limits.

Cho Byung-Joon, chief of the district government's flood control and disaster prevention division, said the professor and other experts would carry out a test before news media and officials later Tuesday to prove their theory.

"When they show the test results to us and with data, we will immediately let people use the fitness club," he told AFP. "But practising Tae Bo in that particular building may have to be banned."
