Shake Map of the Guangxi Jingxi M_S5.2 Earthquake

Using the time history of ground motion, based on the attenuation law and propagation characteristics of ground motion, the interpolation calculation of grid discrete points in the scale of 0.1°×0.1° is carried out, and the continuous broadcast ground motion map and peak ground motion contour map with time interval of 4 s are drawn. It shows the propagation process and attenuation characteristics of ground motion after earthquake. The calculation results show that the maximum value of horizontal acceleration is 55.08 cm/s², which is equivalent to seismic intensity VI. The calculation results are basically consistent with the field intensity survey results.
