I heard 30 days on the radio news back when it happened(1985). It looks like it was actually maybe a week.
Now why would the news media fabricate such a thing.

“At least six infants, five girls and a boy, have been pulled from the debris of two hospitals. All were trapped for four to seven days, yet suffered only minor injuries.”
Thanks, do not remember this at all. Glad the babies were saved!
