Watch: Shocking video shows the exact moment a 12-story condo in Miami partially collapsed

Footage of the 12-story building that collapsed in Surfside, Fla., is going viral on social media as onlookers share their opinion about the harrowing incident.

According to the Miami Herald, the oceanfront condominium tower suffered a partial collapse in the early hours of Thursday, June 24. Surfside Mayor Charles Burkett confirmed more than 70 of the building's 130 units were destroyed and approximately 35 survivors were pulled out of the debris.

A total of 10 victims were treated by first responders at the scene while two others were transported to a local hospital. So far, only one person has been confirmed dead but local authorities believe this number will rise as the building is assessed.

After witnessing the footage, many Twitter users have asked the same questions: how did this happen and why?

One Twitter user tweeted, "It's a sinkhole under the building the ground under it collapses making the building unstable. No conspiracy.. spend that time thinking about the people that need to be saved and helping the universe with that."

Some users also shared some of the disturbing details they noticed in the video. "Oh man. Someone's lights were on in a middle unit on the 9th floor," one Twitter user noted. "What they must have been thinking and feeling. Terrible."
