Lawyers probably think it is good for business. Good to know there are experts at this kind of stuff, might be better to consult them beforehand though.

On July 5, 2011, a 39-story shopping mall called the "Techno-Mart" in Gwangjin-gu, Seoul, shook violently for 10 minutes and was evacuated for two days. After study, it was determined that about 20 people performing Tae Bo exercises to "The Power" caused the building to vibrate by creating a mechanical resonance. The tentative conclusion was the consensus among the six professors from an architectural institute and vibration measurement experts who participated in a recreation of the event. The Architectural Institute of Korea was scheduled to release the final results of the safety inspection later in 2011.
