I'm not sure what you need to configure, but you can definitely get iPhone alerts to arrive before you feel the earthquake. Not sure why your iPhone didn't alert you while your android did as it should be from the same local data source.

I really wish we had something like NERV but for SF, NERV works so well whenever I'm in Japan. It will literally show you a countdown of exactly when you'll feel it and it's very accurate, and you can see a livemap of monitoring stations reporting it in real time as the wave makes its way towards you.
