Rescue teams are still active, but with the help of firefighters, dog units and cranes. More than 2500 people at work.

A noise was heard from the rubble, without the rescuers being sure that they were of human origin. Microphones placed on or near the ruins did not detect any sound, but a knock was heard which gave hope to the rescuers.

One of the four victims has also been identified, according to the Miami-Dade County Forensic Service. This is Stacy Fang, mother of a 15-year-old who was rescued from the rubble Thursday morning. But Mrs. Fang, who was taken to the hospital, did not survive.

Early Friday evening, Global Affairs Canada said at least four Canadians may have been affected by the collapse.

The drama took place at the Champlain Towers South complex in Surfside, a few miles north of Miami Beach, around 1:30 a.m. Thursday.

The reasons for the collapse of the housing complex are still unknown, but hypotheses multiply.

Florida Governor Ron DeSantis said Friday that the families of the victims were as well right to know Why the building collapsed and the state will do everything in its power to find out.

Many hypotheses

to me Washington Post, Building It was built in 1981 on a restored wetland.

I don’t know if the collapse was expected, but we found out that the building was moving in the ’90sShimon Wodwinsky, professor of environment at Florida International University (FIU) told CNN.

Mr. Wdowinski is one of the authors of a 2020 study showing that the building underwent a subsidence of about 2 mm per year between 1993 and 1999. However, the available satellite data were insufficient. To determine whether the deterioration has continued immediately thereafter.

By itself, the subsidence of the ground will not cause the building to collapse., then guarantee SonFlorida International University In a press release.

Officials said work was underway to upgrade the building to the required level, including on the roof. However, they believe that it is unlikely that this work was the cause of the collapse.

Investigating this will likely take several weeks, among other things, to allow structural engineers to examine blueprints and the way the building was constructed, take samples of steel and concrete, and look for signs of corrosion.

Pictures taken by a security camera showed that the center of the building appeared to have fallen first. Then the part closest to shore vibrated, collapsing seconds later into a huge cloud of dust.

Rescuers Challenge

Fire Marshall Jimmy Patronis said the work of emergency teams is not easy.

Rescuers use the building’s underground garage in particular to access the rubble from below. Debris falls on them as they go about their work, as well as on those who dig among the rubble at ground level.

The debris also contains a lot of combustible material that can ignite, according to Patronis. By spraying to prevent a fire, water is added to the building. The large weight of this water can threaten the integrity of the building.

Besides the seriousness of the operations, the weather conditions were challenging. A storm began at about ten in the evening Thursday, carrying heavy rain until the next day without interrupting the search.

A fire on the north side of the building had to be brought under control.

The search lasted for about two days.
