- Notification based on expected seismic intensity
The terminal user can choose whether to report an earthquake early warning of seismic intensity 3 or higher or seismic intensity 4 or higher. - Control based on accuracy information, etc.
Earthquake Early Warning is an emergency earthquake early warning (business) that uses the data of more than 100 gal announced by the Meteorological Agency and the data of one observation point in order to make prompt announcements. - Control by emergency earthquake early warning (business) for deep earthquakes
The earthquake early warning is an earthquake early warning (business) that does not distinguish between deep earthquakes. - Notification content
The earthquake early warning will announce after the sign sound, "Earthquake early warning. An earthquake with a seismic intensity of about XX will (immediately) occur in about XX seconds." Please - Handling of cancellation notices
The Earthquake Early Warning will issue a cancellation notice for both the issued Earthquake Early Warning (Business) and the non-issued Earthquake Early Warning (Business). - Handling of test reports and training reports
When a training report from the Japan Meteorological Agency or a test report from a business operator is implemented, you can set the operation of the terminal and whether to notify or not.
