  In this article, for any Seifert fibered integral homology 3-sphere, we give
explicit modular transformation formulas of homological blocks introduced by
Gukov-Pei-Putrov-Vafa. Moreover, based on the modular transformation formulas,
we have explicit asymptotic expansion formulas for the
Witten-Reshetikhin-Turaev invariants which give a new proof of a version by
Andersen of the Witten asymptotic conjecture.
