Emergency Earthquake Alert Receiver 【Introduction to Differences with TV and Mobile】

Explaining the difference between the "alerts" distributed via television and mobile devices and the "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- weak or higher is predicted and observed by two or more seismometers, 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 at any seismic observation point reaches 100 gal or more, and the magnitude is 3.5 or higher, or the maximum predicted seismic 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 the difference in information updates. "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 when shaking is coming."
