GraGraph home earthquake meter

No, it’s not a predictor of impending quakes, but the GraGraph will sound an alert and tell you how large the earthquake is on the Richter scale (anywhere from 3 to 10).

Hopefully, you’ll never have to use it, so for that reason, it has a built-in LCD clock, alarm and night-light! The GraGraph will also record prior seismic activity. It runs on 4 AA batteries.

This is a Japanese product, but you can snag one from an importer of Japanese products.
