Nowadays there are many effects from the earthquake impact to the constructions and architectures for the example the pagodas, hence this senior project is focused the earthquake activities and hazards of pagodas in the northern of Thailand by the earthquake evaluation from Incorporated Research Institutions for Seismology (IRIS) database. As a result, the data quality improvement found that there are 1,450 earthquake data. The evaluation of earthquake activities can do these by finding the maximum earthquake magnitude in the unit of moment magnitude (Mw) by using the surface rupture length and calculating form the relation of Well and Coppersmith (1994) and estimated by using a and b from the relation of Gutenberg and Richter (1994) and evaluation of earthquake hazards will represent in term of Peak Ground Acceleration, PGA, estimated by Deterministic Seismic Hazard Analysis, DSHA, and the theory of Probabilistic Seismic Hazard Analysis, PSHA. From the evaluation found the largest earthquake magnitude is around 6.8 - 7.1 Mw and the period of 50 years, the probability of maximum earthquake is 6 but the probability of occurrence is significantly low, consequently the earthquake hazards probability risk of pagoda in the northern of Thailand is too low to rupture by the future earthquake.
