Im reading things like
"Several buildings were reported destroyed in the blast and a nearby nursing home was damaged.
There were reports earlier that people were trapped in the nursing home and in an apartment building."
Was this on the other side of the explosion view in the video? Cause how were the two in the car taking the video not destroyed?
Most of the explosion seems to be directed into the air above them. #1 reason they lucky..a bleve may have turned them into burn toast.
< physics lesson>
Reason why the shockwave destroyed buildings yet the vehicle stayed intact. Surface area and strength(and flexibility..) The vehicle has less surface area and is way stronger and more flexible than a building is. A building can have a huge surface area that can be flat..if made of brick or something like that..it doesn't flex much before crumbling into a bunch of pieces. Now..the vehicle absorbed the shockwave and apparently was moved sideways..if it was bolted to the ground or something like that..it would have been way worse for those being inside since it probably absorbed alot of the blast..altho alot still got inside and may have shattered their eardrums and maybe hurt internal organs and such..but the idea is the truck absorbed the shockwave and was able to move. A building is not able to be moved..when the shockwave hits the wall it pushes it..and said wall crumbles to pieces. So its all about surface area and how flexible said object is...and if it can move.
Hope that made some sense Ok ill admit..I loved physics in high school and if I could live with math above basic stuff..I would be an engineer
