I don't know what was meant by the term "blow up."

If you mean "explode," I'd say that's unusual (except for the fact that you have one or more fuel trucks involved here).

If you mean "lifted vertically in a sudden manner," I'd say it would not be all that unusual. It looks like one or more sections toppled instead of just collapsing, so the rotation of the slab (toppling motion) could easily lift cars, people, etc. up in the air.

I can only go by the words the reporter said, she said the lady in the red car said if it was 30 seconds later she does not think she would be alive.

She also said that objects were blowing upward and then there was downward movement.

Getting dark and difficult to see what is happening.
