Statistics on the death statistics of earthquakes in Sina.com were collected. The logistic function was used to fit the data of earthquake cases. The results showed that: (1) The number of earthquake deaths was reported. There is a good correlation between the curves presented at the time and the more deaths there are, the longer it takes to determine the final number of deaths. (2) The shorter the time when the number of earthquake deaths approaches the total number, the stronger the rescue ability.(3) The data show that in the face of catastrophic earthquakes with more than 10,000 deaths, especially the huge earthquakes that caused the tsunami, relying solely on the local rescue capacity is obviously insufficient.
