N2 - The M6.2 earthquake occurred in May 2014 in Chiang Rai province, in the northern most Thailand and caused widespread damage within 30 km radius from the epicenter. As a large portion of the Chiang Rai province is characterized by various subbasins within, it could be affected by moderate to large earthquakes. This work measures the Vs30 of the Chiang Rai province with the spatial autocorrelation (SPAC) method using seismic ambient noise. Shear wave measurements at 120 sites in Chiang Rai indicate that the Vs30 varies from 193-700 m/s which can be classified as soil type classes D (stiff soil) and C (very dens soil and soft rock) based on the National Earthquake Hazards Reduction Program soil type classification. The result will be integrated to the production of the national seismic hazard map of Thailand in the future.
