- Abstract:
- According to the China Earthquake Intensity Table,we use the ground motion records of the Yangbi,Yunnan MS6.4 earthquake on May 21,2021 obtained by strong-motion stations to calculate the instrumental seismic intensity.Then we compare the map of instrumental seismic intensity and the map of macro scopic seismic intensity of the Yangbi MS6.4.We find that the two maps have the same highest intensity and the similar long axis of the isoseismal lines,but the area and shape of each intensity zone are different; the consistency of the instrumental intensity at the stations and the intensity on the corresponding survey sites is 81.25%,and the ratio of 1-degree deviation is 93.75%.It can be seen that the instrumental seismic intensity can objectively reflect the actual earthquake damage to some extent.
