Realization of earthquake function of mobile phone

1, earthquake early warning information reception

The mobile phone detects the propagation speed and intensity of seismic waves through sensors such as built-in seismic sensors, and judges whether the earthquake reaches the early warning condition according to the preset threshold. Once the warning conditions are met, the mobile phone will receive the earthquake warning information.

2. Interpretation and processing of early warning information

The mobile phone interprets and processes the received earthquake warning information through the algorithm and data provided by the earthquake warning analysis system. The mobile phone will analyze the magnitude, source and expected influence range of the earthquake, and give the user corresponding early warning tips.

3. Transmission of early warning information

Once the mobile phone receives the earthquake warning information and completes the interpretation, it will send the warning information to the user in time through the wireless communication network. This process is usually carried out by SMS and push notification to ensure that users can receive earthquake warning information in time.
