| Abstract | The two active faults, Ranong (RNF) and Klong Mauri (KMF), are the two primary sources of the earthquake in the study area, Phuket. The approximated earthquake magnitude which is estimated to trigger is 7 to 7.5, respectively. Therefore, the study aims to find out where the most impact area under magnitude 7.5 seismic loading is and generate the earthquake impact map of the Phuket Province. The review shows that many authors have researched the seismicity hazard levels in Southern Thailand, including Phuket, from the geological points of view. In this study, the author approached the impact level by analyzing the stress changes of the soil layers under quake from the geotechnical point of view. The nine SPT sites located around the Phuket Province are simulated earthquake modeling with the synthetic ground motion data (maximum PGA value of 0.7898g). The map for maximum stress changes is generated. The maximum stress changes occurred at site no 11,14 and are followed by 31,33,12. Those areas where the residual pore water pressure generation is high and the permanent deformation occur with the highest shear strain value of 0.05%. Under the high ground motion, the stability of the building is vital. The expert says, "Earthquakes don't kill the people, but buildings do" Therefore, the intensity of the building in each province is considered one of the factors. The most impacted area due to the earthquake will be MA KHAO, TALAT YAI ,TALAT NUEA, RAT SADA, and CHALONG, where the stress changes and building intensity are significant. |
