Taroko Rockfall Response Program Situation
I. Origin and basis
The scenery of Taroko Gorge is renowned worldwide. In 2017, the national park received over 4.65 million visitors. Rockfalls are a natural hazard that put visitors at risk when they are on the park trails.
When Minister Without Portfolio Chien Tai-lang inspected Taroko under the instructions of the National Defense Group he pointed out that rockfalls put visitors at risk and said that the problem needed to be urgently resolved. He stated that Tunnel of Nine Turns (Jiuqudong) should be given priority and instructed Taroko National Park Administration to promptly submit a program to the Executive Yuan. Also, on June 28, 2014, Premier Chiang Yi-hua expressed concern about the “rockfall protection” handling situation when on an inspection visit to Taroko.
II. Scope of program plan
- The scope of the main plan is the sides of the most spectacular section of the Central Cross-Island Highway-Tianxiang (Provincial Highway No. 8 169K+940 to 188K+500, 18.56 kilometers in total) and along both sides of the road.
III. The main strategy and objectives of the Program plan

The maximum insurance benefit per person of the National Park Accident Liability Insurance's additional rockfall insurance was increased to NT$5 million in August, 2014.
- Early warning environmental monitoring
- The park Administration has established a routine patrol monitoring mechanism; for example, Swallow Grotto (Yanzikou) Trail is patrolled every day and findings used as the basis for deciding whether the trail is open or closed, and the Directions for Closure of Leisure Facilities and Areas of Taroko National Park Administration have also been formulated as the basis for management in the event of earthquakes, typhoons or torrential rain.
- Geological and hydrological surveys have been carried out in the Tunnel of Nine Turns(Jiuqudong), Swallow Grotto(Yanzikou), Eternal Spring Shrine(Changchun Shrine) areas and other areas, related maps collected and LiDar (Light Detection and Ranging), aerial photography, and other technology, used for analysis, assessment and surveying to protect against disaster-causing factors.
