Buffy - 1x12 - Prophecy Girl
There’s freaking earthquake. It destroys much more than can be seen, but items in the library include a vase, a plate carrying a teacup (but, surprisingly, the teacup survives the fall off the desk), and several of the bookshelves on the upper level. The wall cracks wide open, as does the floor. Later, one of the upper level railings is seen broken in half.
A pack of vampires kill several students in a school room. A table is broken in half. There are a lot of things knocked down, and there’s blood on a lot of things, but most of it seems like it could be picked up and cleaned off.
Cordelia drives her car through two doorways - one leading into the school and one in the hallway - both are completely destroyed, as is some of the wall surrounding them. Vampires break both of the windows on the Library doors. Someone, likely The Master, breaks a hole in the Roof Access door. A demon breaks through the floor of the Library, then later tosses Giles through the large table in the center of the room. The table is demolished. Buffy throws The Master through a window dome on the roof into the Library.
Also damaged in the earthquake, but specifics can’t be determined.
