SEISMIC INTENSITY IN XINJIANG BASED ON FOCAL MECHANISM SOLUTION RESEARCH ON ATTENUATION RELATIONSHIP
Collect 130 destructive earthquake events with intensity data from 1716 to 2022,supple-ment the recent destructive earthquake intensity data in Xinjiang,and classify 124 seismic intensity maps and 281 pairs of intensity circle long and short axis data.The mathematical method is used to fit the seismic intensity attenuation model of different time nodes and different focal mechanisms in Xinjiang.It is found that in the process of intensity attenuation,strike-slip and reverse-fault earth-quakes are slightly different.Different seismic source rupture properties will affect the long and short axes of intensity attenuation relationship.Therefore,we can use it as a correction factor to quickly e-valuate the intensity influence field of earthquake disasters.After the earthquake occurs,the long and short axis data of the intensity circle can be modified and improved to evaluate more accurately.
