Earthquake early warning refers to a system that can predict the possible occurrence of an earthquake from a few seconds to tens of seconds before it occurs. Such a system can give people enough time to take appropriate protective measures and avoidance measures before an earthquake strikes, reducing losses caused by earthquakes.

The significance of early warning during earthquakes is very important. Earthquake is a devastating natural disaster that can cause huge losses and casualties in a short period of time. The earthquake early warning system can predict the arrival of earthquakes in advance, providing a time window for rescue and avoidance. In this way, we can rescue those trapped and do a good job in post-disaster response and recovery.

The implementation of earthquake early warning systems requires the use of advanced scientific and technological means and big data analysis technology. For example, precursor earthquake signals, seismic wave vibration data, etc. will be recorded to predict the possible occurrence and propagation time and area of ??earthquakes. These data and information will be analyzed and processed, and the public will be notified or automated protective measures will be taken through phone calls, text messages, broadcasts, etc. At present, many countries and regions around the world have established earthquake early warning systems to ensure the safety of human life.
