According to Wu He-rong, head of the Interpretation and Education Section at Yu-shan National Park Headquarters, the Ministry of the Interior resurveyed Yu-shan after the 921 Earthquake and found that it had shifted over 40 centimeters in a west-northwesterly direction, but its height was virtually unchanged.
玉山國家公園管理處解說課課長吳和融表示，921 地震之後，內政部曾經重測玉山主峰高度，結果發現它向西北西偏移了四十幾公分，但高度幾乎沒變。
