At least 13 people were killed and hundreds injured in China Wednesday after a massive explosion rocked the northern port city of Tianjin — triggering shockwaves that could be felt up to six miles away.
The detonation was sparked by a shipment of explosive material that erupted around 11:30 p.m. at a terminal in the Binhai District, around 72 miles southeast of the capital of Beijing, according to state broadcaster CCTV.
The blast, which was caught on camera at numerous angles, was so powerful that it knocked down anyone in its pat
h, and the heat it generated could be detected from space, according to Russell Dengel, a science and engineering researcher at the University of Wisconsin.
After the first explosion, witnesses reported feeling another blast just 30 seconds later, according to the BBC.
Breathtaking footage of the explosions and the towering inferno that followed have popped up on Twitter and China’s popular social media site, SinaWeibo.com.
In one video, two people can be heard frantically describing the scene.
“Wow! Everything is shaking. Is it a nuclear bomb!?” a person says, according to a translation by Business Insider. “The windows on the building have shattered. I hope our building doesn’t collapse.”
In another video, a camera that was recording the explosion from a good distance away can be seen getting toppled over by the shear force of the blast.
“At the time of the explosion the ground was shaking fiercely, nearby cars and buildings were shaking, a few buildings’ glass all broke and everyone started to run,” an eyewitness told local media, according to BBC.
Tianjin is a major industrial port to Beijing, which is currently home to an estimated 7.5 million people.
