Disaster Alerts at the Speed of Sound
Jun 3, 2014, 1:31 PM
Millions of people have now seen their phone shake and heard it wail with news of an impending tornado or other disaster. Two years ago the wireless industry rolled out a free service known as wireless emergency alerts, and wireless carriers representing more than 98 percent of subscribers agreed to participate.
People with older phones, however, may not be able to access the alerts. Brian Josef, general counsel for the CTIA—The Wireless Association in Washington, D.C., recommends checking for the capability when buying a new phone and. For your current phone you can check with your carrier’s customer service office to see whether you automatically get the alerts.
People who can’t receive the texts, or who want a double layer of information, can sign up with local emergency management offices and get alerts via phone, text, email and in some cases Twitter—although sessions at the recent Preparedness Summit in Atlanta indicated that while Twitter is growing, it is still not used by many local and state health departments. Check the bottom of your health department home page to find the Twitter handle, if there is one.
Josef also points out that you may find that a neighbor got an alert and you didn’t—but that’s because the alerts are geo-targeted. If you and your neighbor were a few miles away from each other when an alert went out, only the one in harm’s way would get pinged.
But the apps won’t do you much good if your phone loses its charge. Preparedness experts recommend keeping a charged extra battery and portable charger on hand, and some emergency radios also include phone/device chargers.
Other tips to conserve your smartphone battery, according to Mary Clark, Chief Marketing Officer of the mobile technology company Syniverse, include:
- Reduce the brightness of your screen
- Close unnecessary apps
- Use text messages to communicate with friends and family
- Send an initial text to those most important detailing your plans
- Turn off unneeded options such as Wi-fi and Bluetooth
