(Miami Beach, FL)  —  First responders are combing through the rubble this hour in search of survivors after a multi-story building partially collapsed in Surfside.  Miami-Dade Fire Rescue says over 80 units are on the scene along the North Beach with assistance from municipal fire departments.  Police say there’s no word yet on what caused the building to collapse, potential casualties, or how many people were inside.  One witness was next door and said it felt like an earthquake.  The building appears to have been more than ten-stories tall.
