Is there anywhere where they define the nature of the threat?
Section 2, quoted by symmetry above - 1 a,b and c must be satisfied before terrorism is applicable. Satisfying 1a requires satisfying at least one item from section 2, which is a list of possible actions which can be considered terrorism. Endangering life, serious violence against people or property, risk to health or safety etc.
Far too broad of course, but still not applicable to Miranda.
