in college, my apartment was in a complex that was destroyed by a gas explosion.
Luckily my building was still standing, but enough of the force hit it to break all the windows, knock everything on shelves into the middle of the rooms, shattered overhead light fixtures, and even split the doorframe to my bedroom door when the door was blown open -- all while i slept under the window facing the explosion.
That was just before 7am IIRC. I was able to grab enough clothes for the night and my toiletries. We were unable to go back into the complex for 3 days to give the engineers time to decide which buildings were safe enough to enter. The building next to mine where the laundry room was located was rubble. Several apartments had second story floors collapse down to the first floor. Walls had cracks, glass was everywhere, and there was no electricity. All the food in the fridge i'd bought 2 days earlier was wasted. I still don't know how I walked through the entire apartment barefoot to check for my roommates without getting a single cut. My bed was filled with the broken window glass.
All this to say, it's not always a simple case of "running in to grab a few items," when so many things could represent a danger. Until you know, you really don't know.
