Quoting "Cook, Dwight E" <cookde AT BP DOT COM>:

His telephone area code indicates that he is in California. I have
seen pictures of household water heaters that fell over during
earthquakes in California. Some types of computer equipment are as
tall in proportion to their width as a water heater, so there is real
reason for concern about equipment falling over during an earthquake.
I am not sure a blanket policy of bolting down equipment is warranted.
A 3494 is nearly as wide as it is tall.

My edition of the "Magstar 3494 Tape Library Introduction and Planning
Guide" (GA32-0279-08) has about half a page of discussion of earthquake
effects (listed under "Earthquake" in the index). This material seems
to be arguing against the idea of a rigid attachment to building
structure. Instead, it recommends flexible restraints that will
decouple the 3494 from the earthquake energy.
