In Puerto Rico, the electricity is out all over the island. How is FEMA instructing people to register or request help? By calling FEMA or registering on the Internet. How do people do that when they have no electricity? In mainland U.S., it used to be that phone lines worked when the electricity went out because a small bit of current was carried in the copper wire. These days, phone lines are fiber optic and require an external power source. From FEMA's website: How to Apply for Assistance: Individuals and business owners who sustained losses in the designated area can begin applying for assistance by registering online at www.DisasterAssistance.gov/es or by calling 1-800-621-FEMA (3362).
