I don't say the whole building mayn't collapse as a result.

Two years later, the building collapsed, and nothing remains of it.

By 1956, the building had collapsed, leaving only a small section standing.

When the building collapsed I felt the pain that those people were going through.

But by the time the workers arrived at 3:56, the building had already collapsed.

Only a little while later - 10, maybe 15 minutes - the building collapsed.

Even as it came the building was collapsing around them.

After they got there, the building collapsed around their heads.

They were taken to an ambulance, when the building collapsed.

However, the building would always collapse after reaching a certain stage.
