Level II Earthquake Motions correspond to which design consideration?

Explanation:
In earthquake design, ground motions are categorized by how often they occur and how severe they are. Level II motions represent a middle-ground scenario: shaking that is significant but not extreme, used to ensure typical structures perform reasonably well under moderate earthquakes while keeping costs manageable. So the design consideration matched to this level is the moderate earthquake case. The milder, more frequent events relate to Level I, while the rarer, more severe events relate to the higher levels, which demand tougher design criteria.
