土壤液化潛勢圖

本圖資包含全臺8縣市之土壤液化潛勢分布，屬於區域性大範圍的圖資，底圖比例尺為1/25000，可提供國土規劃及防災規劃參考，工程個案的規劃設計則需要更近一步的調查分析，才可判定液化潛勢。
此圖資呈現的土壤液化潛勢，係由各公共工程鑽探及地調所鑽探岩芯及試驗結果，依據建築法規規範方法計算各地之土壤液化潛勢，並將潛勢分為高、中、低三級。已完成的圖資範圍包括臺北市、新北市、新竹縣、新竹市、宜蘭縣、臺南縣、高雄市、屏東縣等平原地區。其他平原區將持續進行調查分析並於完成後陸續公開。

This geospatial dataset covers the soil liquefaction potential distribution across eight counties and cities in Taiwan. It is a large-scale regional geospatial dataset with a base map scale of 1:25000, which can serve as a reference for national land planning and disaster prevention planning. However, for the planning and design of individual engineering projects, further investigation and analysis are required to determine the exact liquefaction potential.

The soil liquefaction potential presented in this dataset is calculated based on drilling cores and test results from public engineering projects and the Central Geological Survey (CGS), following the methods specified in building codes. The potential is categorized into three levels: high, medium, and low. The completed dataset covers the plain areas of Taipei City, New Taipei City, Hsinchu County, Hsinchu City, Yilan County, Tainan County, Kaohsiung City, and Pingtung County. Investigations and analyses for other plain areas are ongoing, and the finished datasets will be publicly released in stages upon completion.
