In Miami, a multi-storey building partially collapsed. Rescue work continues for several days, hopes of finding people alive are fading.
The incident occurred on June 24 in the town of Surfside, which is part of the Miami metropolitan area.
Survivors said they were jolted awake around 1:30 a.m. by fire alarms, falling debris and the feeling of the ground trembling.
Fiorella Terenzi, an associate professor at Florida International University who lives in a neighboring building, Champlain Towers East, said she woke up early Thursday to a loud noise.
The sound “was like a big thump all of a sudden,” she said. At first Ms. Terenzi thought it was thunder, but then she heard sirens. When she left the building, dust was everywhere.
