Abstract: In recent years, destructive earthquakes take place frequently in the western region of China. In accordance with the requirements of the China earthquake administration, earthquake field work team should quickly rush to the earthquake site to carry out relative intensity investigation and disaster investigation etc. and release the seismic intensity map to the public within 3 ~ 5 days to support the earthquake emergency rescue, post-earthquake recovery and reconstruction. This paper analyzed the seismic intensity of April 20, 2013 M7.0 earthquake and found that there are significant difference between the seismic intensity, which is mainly based on the damage of residential buildings, and other seismic secondary mountain disasters given priority to with the landslide disasters and the distribution of ground motion on behalf of the peak acceleration, etc. Furthermore, the seismic intensity is not well consistent with the seismogenic structure, source distribution, failure process and focal mechanism. Another few earthquakes have similar problems. Moreover, some seismic intensity map revision is not conducive to use. With no intensity anomaly areas (points), seismic intensity distribution is more and more similar to total focus on space ellipse and its scientific is in doubt. Based on analysis on these problems, this paper further discussed seismic intensity rapid reporting.
