Rescue operations are back on as precious minutes – and the hopes of survivors – tick away.
Officials say 145 people are still missing. Eighteen are confirmed dead. The youngest victim was just four years old.
President Biden visited the site and met with families and survivors.
He said: "They had basic heart-wrenching questions: 'Will I be able to recover the body of my son or daughter, my husband, my cousin, my mom and dad?' Jill and I want them to know we are with them and the country is with them."
