The explosion was so powerful that cars melted and homes crumbled. About a mile away Woodruff found vehicles dented, with their windows blown out. He also explored a nearby migrant camp that was completely destroyed. In another area, Woodruff entered an office building, where glass and debris littered the floor.
The first blast happened at 11:30 p.m., followed by a second explosion just 30 seconds later, according to a statement from the Tianjin Fire Department.
