Reasons for failure to receive earthquake warnings

First of all, we need to understand the information transmission method of earthquake warnings. Earthquake early warning is to collect seismic wave data through professional earthquake monitoring equipment, determine the possibility and time of earthquake occurrence, and then transmit this information to users through the network. Therefore, if the user's mobile phone is not connected to the Internet or the network signal is poor, it may not be able to receive earthquake warning information.

Secondly, the sending of earthquake warning information relies on the cooperation of mobile phone manufacturers and operators. Although the National Seismological Administration has deployed earthquake early warning systems nationwide, the specific sending of early warning information still needs to be completed by major mobile phone manufacturers and operators. This means that not all mobile phones can receive earthquake warning information, which may also be one of the reasons why some citizens cannot receive SMS reminders.
