The way the whole street went up in a line like that, I bet it was a sewer gas explosion.
Edit for the [dead]: sewer gas isn't gasoline in the sewer. Sewage produces hydrogen sulfide, an explosive gas. There are many videos online of sewers blowing up after people drop lit cigarettes into sewers and in those videos the street is often blown apart like is shown in the OP video.
