Earthquake Meter Lets You Know When The Earth Moves Under Your Feet

Next time you're wondering if the earthquake of the century is starting to hit, this GraGraph earthquake meter will let you know just how bad that tremblor is, in real time. Once an earthquake starts (it doesn't say how strong, could mean a lot of false alarms), this little alarm-clock-sized device lets out a powerful wail, and then helpfully suggests what you might do next. Presumably this gives you time to get out of your house before it falls down around you. It's peace of mind for $85, but come to think of it, if there's a really bad earthquake, do you really need an alarm to tell you to get the hell out of there?

Gragraph features:

• Perceives shaking, and indicates on display
• Warns of shaking with sound and voice
• Indicates level from 3-10
• Keeps record of previous seismic activity
• During the night, it activates a safety light
• Calendar/Clock function

 As one of the most earthquake prone areas on the planet, Japan is constantly in a state of alert as most citizens await "the big one" scheduled to hit any day now. Now a new gadget called the GraGraph has been introduced for those who want to know exactly how big an earthquake they're experiencing in real-time, all from the comfort of their soon to be demolished homes.
Once an earthquake begins the device sounds a terrifying alert (the episode of "24" when nerve gas was released at CTU comes to mind). The alert is followed by a soothing electronic voice that lets you know the strength of the earthquake and exactly what you should to do save yourself. If you're a resident of the U.S. earthquake hotspot San Francisco, all this apocalyptic fun can be yours for just 32,800 yen ($285). — Adario Strange
