With all of that, it's still possible to just be unplugged, or not listening to local media, and not get warnings.
At least a tornado or hurricane gives a warning. You're completely out of luck with earthquakes (former Los Angeles girl here).
That's why I have a weather radio that has a flashing light and a siren... it also warns in case of earthquakes, volcanoes and landslides, but I think those would be after the fact warnings. Not that I need them here anyway.
