According to the NEEB, because during an earthquake the tunnel would move in tandem with the mountain range, it would actually be the safest place to be. The tunnel would only risk destruction from an earthquake if it was located in an active fault zone. Since the Hsuehshan Tunnel does not pass through an active fault zone, people have no reason to worry.
國工局表示，由於地震時隧道會與山脈一起擺動，反而是最安全的地方，除非位在活動斷層帶上，才會發生整個隧道被撕裂的情況，而雪山隧道行經區域都沒有活動斷層，民眾可以放心。
