Overturning forces when they are referred to in an engineering or architectural context refer to those forces that are excerted by enviromental forces, ie wind, water(if you have a dam), and earth. They do not refer to possible forces in the future such as bombs, plane crashes, etc. Since I don't have an engineering dictionary with me, I'll provide you with an "in context" definition

Study this one carefully, it will provide the definition you are looking for, both in words and equations.

Events in the future, such as bombs, plane crashe, etc. are referred to as catastrophic events. Events mean one time, over a short period. Forces mean ongoing, throughout time. A bomb blast is an event, a catastrophic one. Wind is a force, an overturning force. Its all there in the link.

Now stop playing cutsie semantics games, you don't even know what the rules are.
