If you live in an area prone to earthquakes and aren’t content with waiting to find out how big that last one you felt was then the GraGraph is for you. This device (which doubles as a clock with time/date) is like having your own seismology lab on your night table: when an earthquake happens the GraGraph will sound its alarm and display the intensity of the quake on the Richter scale.

Little tremors happen all the time that we don’t feel but the GraGraph will measure the tremor and display it for you. And should The Big One ever hit the gizmo will give you ideas about what you should be doing instead of standing there listening to it. Thankfully it’s small enough to scoop up as you make a dash for the safety of a doorway.

Priced at $85 it’s more expensive than your average digital clock but now you will know when the earth is literally moving under your feet.
