Differences between emergency earthquake alert receivers and television/mobile phones [Disaster Prevention / Earthquake and Tsunami Measures]

Explaining the difference between "alerts" distributed via television and mobile devices and "forecasts" received through emergency earthquake warning receivers!

There are two types of emergency earthquake alerts: "warnings" for general use and "forecasts" for advanced users. The general "warning" is issued when a maximum seismic intensity of 5- is predicted and observed by two or more seismic stations, targeting areas with a predicted intensity of 4 or higher. This is mainly distributed through television, radio, and mobile devices. In contrast, the advanced "forecast" is issued when the amplitude of P-waves or S-waves exceeds 100 gal at any seismic observation point, and the magnitude is 3.5 or higher, or the maximum predicted intensity is 3 or higher. This is primarily received through dedicated receivers, systems, or apps. The general "warning" is typically issued once, while the advanced "forecast" can be repeatedly issued as more accurate intensity predictions become available over time, reflecting a difference in how the information is updated. "I want to ensure the safety of customers and employees as quickly as possible." "I want to protect my company's products and assets from disasters." "I want to build a supply chain that is resilient to disasters." "I want to reduce secondary and tertiary disasters caused by earthquake shaking." From "preparation for unexpected shaking" to "preparation that knows shaking is coming."
