Abstract

Liquefaction Susceptibility in the Northern Provinces of Thailand

Highlights

INTRODUCTIONThere are quite a few moderate earthquakes being felt (Table 1) in Thailand
Not until recently that Thailand becomes aware of the threats from earthquakes
The most common set of physical variables adopted in several liquefaction studies is the Cyclic Stress Ratio (CSR) and the corrected SPT resistance

Summary

INTRODUCTION

There are quite a few moderate earthquakes being felt (Table 1) in Thailand Epicenters of those recent medium earthquakes were located in the northern and western parts of the country. Warnitchai and Lisantono[1] formulated a database containing instrumental data of earthquakes from 1910-. They indicated that earthquakes of magnitude (ML) of 6.5 with maximum ground acceleration of 0.2g may occur in the northern and western parts of Thailand (Fig. 1). Its existence initially infers certain levels of liquefaction risk. This has been further confirmed by evidence showing trace of liquefaction (Fig. 3) found from a trench exploration in the area. Probabilistic study and dynamic analytical results is used as a primary tool for detail evaluation
