To meet the practical needs of rapid response and efficient disposal of earthquake emergency,an automatic trigger software of earthquake emergency command technology system based on Earthquake Instant Messenger(EQIM)is designed and implemented. The seamless connection between the software and the EQIM database is accomplished,which can automatically monitor the latest seismic events. When the corresponding emergency thresholds are reached,the key emergency business systems such as the earthquake disaster rapid assessment system,video conference system,command and dispatch system,and central control system are automatically triggered and activated. As a result,the whole emergency command technology system will automatically start and the necessary emergency services products will automatically output,so as to achieve the goal of highly efficient emergency.
