I’m fairly confident that California is due to for the ‘big one’.   Yes, that’s a bit apocalyptic of me, but a bunch of dudes with protractors and white coats seem to think so too.  The Gragraph is Seismograph a Home Earthquake Seismograph and should warn you of impending quakes and provide a digital readout of the Richter scale.  It looks like it includes a clock and some audible alerts in case you wanna time your table and doorway ducks.

Available for $150.
