Soil Liquefaction Potential Assessment in Northern Thailand

摘要

The aim of this study is to analyze liquefaction due to an earthquake. Specifically, an earthquake which was felt in northern Thailand that is sensitive to liquefaction. The first liquefaction was discovered in Thailand at 6.8 moment magnitude earthquake occurred in the central region of Myanmar causing widespread liquefaction in 2011, and Liquefaction occurred again at 6.3 moment magnitude in Mae Laos, Chaing Rai Province in 2014. Liquefaction has been observed in a wide area in Chaing Rai province in two different studies of geographical evidence that analyzed the resulting opportunity of liquefaction in the Northern of Thailand by the factor of safety against liquefaction. The subsoil profile and peak horizontal ground acceleration were analyzed in this study. The results can be used to prepare safeguards that reduce the danger from liquefaction in northern Thailand.
