"We were very concerned that this might happen and in fact it did," she said, wondering if it could have been a result of a tremor.

She said they moved their van moments before the live shot, just in case the structure fell.
"This really shows how incredibly dangerous the situation is here, it really hits home when you see the rubble and dust for yourself," said Nadeau.
"It was shocking to see this home collapse right in front of us, knowing that it belonged to people and now it's gone," she said.

You think of the terror they would have felt when they were lying in their beds when the earthquake hit. It really is just so sad."
More than 70 people were killed in the 6.2 magnitude earthquake, and dozens remain missing. Rescuers are struggling to reach some remote towns, and one, Amatrice, "is no more," according to its mayor.
