Also it's not bad to develop a habit of checking
the USGS Earthquake Hazard Program website on a daily basis. Large quakes are
usually (but not always) preceded by smaller quakes. By becoming aware of normal quake activity in your area you can see when there's an increase in small quakes that might herald a large event.
The above listed website also offers
email and text message alerts if one is so inclined.
