Chinese city implodes 19 buildings in 10 seconds

Nineteen buildings - ranging from seven to 12 storeys - were demolished in less than 10 seconds in central China to build one of the world's tallest building standing 707-metre tall.
The buildings ranging from seven to 12 storeys high were razed just before midnight on Saturday in Hankou, Hubei province, marking the country's largest building implosion project, the South China Morning Post reported.
The operation covered an area of more than 15 hectares and involved more than five tonnes of explosives distributed in 120,000 locations.
It was the third implosion operation carried out in the area, demolishing a total of 32 buildings so far that will make way for a marquee business district of the city.

The project is said to have attracted more than 30 billion yuan in construction investment, which will include one of the world's tallest building standing 707-metre tall, a cross-harbour tunnel and an underground complex.
The world's current tallest building the 830-metre Burj Khalifa in Dubai.
Wang Xuguang, an implosion expert at the Chinese Academy of Engineering, said that the event was the first attempt in China to demolish a large complex of buildings in a bustling metropolitan area.
Wang said that by using the implosion technique rather the traditional demolition approach, the city saved more than four months to prepare the building site.
