Yes...I understood exactly what you meant. I was just commenting on how these windows (in adjacent buildings/homes) look broken, as well....similar to how you described your situation.
It took a 3 story building an reduced It to about 10 feet tall. It also blew the siding off closer houses. Lots of broken glass.
The cause was an undetected gas leak from under the sidewalk. It leaked into a basement and when the furnace came on, it blew.
