Earthquake warnings pop up on computer screens in Japan for subscribers to the Urgent Earthquake Bulletin service from NTT telecommunications company.
When a quake alert is issued by the Japan Meteorological Agency, the NTT service will automatically open an alert window on a personal computer screen. An alarm sounds, and the warning window displays the estimated seismic intensity and counts down to the estimated arrival time.
NTT is also selling a standalone earthquake warning device called the Urgent Earthquake News Flash FLET’S Type. Flashing LED lights and an audible alarm indicate a quake warning and the quake arrival time and a countdown are announced. External warning lights can be connected to the device. FLET’S is an NTT brand of high-speed ADSL and fiber optic services.
NTT says the FLET’S quake warning service offers more precise data and details than the information that is offered in warnings on TV and in optional services that send email quake alerts to cell phones.
A fixed-line cordless phone from Sanyo also automatically receives and loudly announces the JMA warnings. The system utilizes a standard telephone line and an included Local Area Network wireless terminal. The 1.7-inch liquid crystal display backlight on the phone handset displays a red warning, a light on the handset blinks, and the wireless LAN terminal lamp flashes red. The phone lamp also acts as a flashlight. (Read more : Phones Ring Earthquake Warnings)
