2. Formulate a policy framework and master plan, including a series of actions, such as preventive actions, post-disaster response and reconstruction.

4. Formulate some guiding principles for earthquake emergency activities taken by relevant institutions. According to these guiding principles, a series of detailed plans have been made.
In addition, Japan has also established an earthquake early warning information system. Although this early warning information system can only provide a few seconds or dozens of seconds of early warning, it is very useful. "For example, if you receive such an early warning, the new train in Japan will stop. There are more than 1000 seismic stations in Japan. When an earthquake occurs, the station closest to the earthquake center can receive the Ranbo, and the time when the shear wave arrives at each station can be analyzed.
