LOS ANGELES (CBS) ― Los Angeles County Thursday released a new EMERGENCY NOTIFICATION SYSTEM.
Residents and businesses can now go online to register cell phones and e-mail addresses with the county so officials can send critical information instantly in the event of an emergency.
Land line phones are already being plugged in to the system.
LA County has implemented a system to notify people about emergencies in their neighborhood, or that effect the county generally. It will call your home telephone to provide information. It is already loaded with listed and unlisted numbers for normal telephone company phone lines (”land lines”).
But - if you want to be notified on your cell phone, or VOIP (voice over IP) telephone (for example, if you use Vonage, or your cable company’s telephone service), and, in particular, if you use these INSTEAD of a “land line,” then you need to register these alternative numbers. The web site to do this is:

Interestingly, the LA Times article about this says “The *city* of Los Angeles already has an emergency notification system for residents living in fire-prone, red-flag areas, but city officials will be able to access the county-wide system too.”
