| Abstract | One of all the natural disasters that cannot accurately predict is earthquake. There are a lot of histories that show many earthquakes around the world since the past to the present. Each earthquake made many damages, large or small area, related with the intensity of earthquake and the properties of area such as type of soil, rock and building etc, like the biggest earthquake on May 5, 2014 that located in Amphoe Pan, northern of Thailand. This earthquake affects economic, society and lives because it is in big city, Amphoe Pan, which consists of many houses and buildings. Many researches show the soil responds and sensitive with strong earthquakes. Moreover the property of Amphoe Muang, changwat chiangrai area is covered soft soil layers. So soil amplification is one of the most important factors that controlling the damage in areas when was strong earthquakes. This study, soil amplification is analyze forty-six sites in Amphoe Muang, changwat Chiangrai, using geophysical data, shear wave, and geotechnical data, soil profile, to consider with SHAKE 2000 software. The result of study area, the maximum value of amplification is 3.58 g and shear wave velocity of this study is 200 to 562 m/s. Finally, there are accurate soil amplification and average shear wave at 30 depths map of the result. |
