About this tag
Early warning systems are critical for disaster preparedness, as demonstrated by Japan's sophisticated earthquake detection network. This system uses thousands of seismometers to detect initial quake waves, estimate magnitude, and send phone alerts, giving people precious seconds to prepare. However, warnings are only effective if people heed them, highlighting the importance of public response alongside technology.
