I hear Governor Gavin Newsome is going to make these MANDATORY in Shake-a-fornia.
PRICELESS -- Thanks Altair, you made my morning !

We have an actual detector, listens for P waves which get here before the S waves you feel. That's why animals seem to know it's coming, they "felt" the P waves.

You don't get a LOT of advance notice but if it's the middle of the night at least you're waking up before it hits.
