A real-time alert system that provides advance notice of an impending earthquake, typically seconds to minutes before the shaking reaches a location.
地震速報を聞いたら、すぐに机の下に隠れてください。
If you hear the earthquake early warning, immediately get under a desk.
このアプリは地震速報をプッシュ通知で知らせてくれます。
This app sends push notifications for earthquake early warnings.
The system is operated by the Japan Meteorological Agency (JMA) and uses a network of seismometers to detect tremors and calculate their intensity and arrival time.
When you hear a warning, immediately protect yourself by getting under a sturdy table or desk, staying away from windows, and covering your head. Do not rush outside during the shaking.
These systems detect earthquakes that have already started and estimate their impact. They provide seconds to minutes of warning, not hours or days.
地震 (jishin) means 'earthquake' and 速報 (sokuhō) means 'rapid report' or 'breaking news'. The term combines these to describe an urgent alert about an earthquake.
This phrase is commonly used in Japan where earthquake early warning systems are well-established. It is not typically used outside of Japan, where terms like 'earthquake early warning' or 'earthquake alert' are more common.
