The heartbeat of a volcano
The geological activity in and around the park was especially interesting to the Korean visitors. Yangmingshan National Park is set mainly in the mountains of the Datun Volcano Group, and because of their close proximity to the city of Taipei, people are concerned about the potential for a volcanic eruption. Therefore the Ministry of the Interior and the then National Science Council (now the National Science and Technology Council) joined forces with various organizations including the Academia Sinica, the Central Geological Survey, and the Central Weather Bureau to set up the Taiwan Volcano Observatory (TVO) in 2011, in order to conduct long-term continuous monitoring of volcanic activity. “We use real-time observation to stay abreast of volcanic activity around Yangmingshan and to track seismic activity throughout Taiwan,” the observatory’s director, Lin Cheng-horng, explained to the Korean delegation. Lin is a distinguished research fellow in the Institute of Earth Sciences at the Academia Sinica.
In recent years, by monitoring seismic activity, volcanic gases, movements in the land surface and changes in ground temperature, the TVO has uncovered many secrets of these volcanoes. For example, in the Dayoukeng area there is an earth tremor approximately every 18 minutes, and these repetitive quakes are like a human heartbeat. “This may be the first time anywhere in the world that seismic activity has been observed with such a heartbeat signature,” says Lin. This heartbeat can serve as an indicator as to whether the volcano will erupt in the future: “We anticipate that before any eruption, this repetitive seismic activity will become increasingly intense.”
After arriving in Taiwan, the members of the Korean delegation not only were able to experience the warmth and hospitality of the Taiwanese, but were also deeply impressed by the beautiful scenery in our national parks. Korea has many national parks, but there are none with high-mountain environments. By contrast, of Taiwan’s nine national parks, three have dense concentrations of mountain peaks more than 3,000 meters tall, something rarely seen anywhere in the world.
For example, Yushan (Mt. Jade) is the highest peak in Northeast Asia, and Taiwan’s high-mountain national parks are centers for the conservation of relict species from the ice ages. Climbing to elevations above 3,000 meters was a novel experience for the delegation members, for Korea’s highest peak, Hallasan, is only 1,947 meters tall, whereas Mt. Hehuan has three peaks above 3,400 meters.

There is historical significance to the grazing water buffaloes at Qingtiangang, which have become a must-see attraction on Yangmingshan.

The new coffee shop at the Xiaoguanyin Visitor Center gives travelers a place to rest and chill out. The delegation from the Gyeongju National Park Office stopped here to try the coffee and enjoy the tranquility of the mountains.
