Facebook, Twitter are useful in emergency

You don’t have to like Twitter or Facebook, or even post to them, but when an emergency strikes, the networking sites can be essential travel tools.

As Hurricane Maria neared the Caribbean, for example, the Federal Emergency Management Agency used Twitter to disseminate shelter information. And when an earthquake rocked Mexico on Sept. 19, the State Department tweeted an emergency message about how to call the U.S. Embassy.

For consumers, the key to using Twitter and Facebook in emergencies is choosing the right entities to follow. Misinformation is common. So who to trust?

Below is a beginner’s guide to finding the most helpful accounts.

Weather

You can follow your favorite weather outlet, but if you want the latest from the horse’s mouth, follow the National Oceanic and Atmospheric Administration’s National Weather Service Twitter account, NWS, which provides regular storm updates.

You can also follow the service’s regional and related accounts, such as the National Weather Service San Juan (NWSSanJuan) and the National Hurricane Center Atlantic Ops (NHCAtlantic), though NWS often retweets the most important updates from those accounts. The primary National Hurricane Center account is NWSNHC.

Safety

The Centers for Disease Control and Prevention (CDCgov) posts health and safety updates. After Hurricane Irma, it tweeted a link to its food and water safety guidelines, as well as home cleanup recommendations.

FEMA (fema) provides information about what it’s doing before, during and after emergencies and how you may be able to get help.

Twitter Alerts and Facebook Safety Check

Use the Twitter Alerts feature for getting information during emergencies. You choose which individual accounts you want to receive alerts from, and if one of those accounts marks a tweet as an alert, you receive a notification on your mobile phone. (Alerts on your Twitter timeline appear with an orange bell.)

In emergencies, Facebook activates its Safety Check tool, which prompts users to let their friends and family know they’re safe and to find or provide help to others.

Transportation and lodging

On a national and international level, accounts to follow include Amtrak and RailEurope, bus lines (like GreyhoundBus and MegaBus), cruise lines, car services, such as Uber and Lyft, and, of course, airports and airlines. Even if you fly only one airline, it can be useful to follow a few. For instance, on Sept. 18, United tweeted that it was canceling some flights and offering travel waivers to and from San Juan, Puerto Rico. Even if you don’t fly United, their tweets might alert you to the possibility that your own carrier might take similar actions.

Airbnb (Airbnb and AirbnbHelp) can be helpful even if you’re not a member. The company has a disaster response program that helps people find temporary accommodations. For instance, recently it tweeted that it was using the program to help people affected by the earthquake in Mexico, allowing Airbnb members to open homes for free to displaced neighbors and relief workers.

When planning a visit to a city, consider following the airports, train stations, bus lines, tourism boards and embassies, as well as your favorite hotels. They can sometimes be sources of emergency information.

Government, tourism

Following local government accounts in your hometown, as well as those in the places you plan to travel to, can also provide current information. Not all government accounts are equally helpful, however. Sometimes tourism board accounts provide more expansive information.

The Caribbean Tourism Organization has been a source of up-to-date information about Hurricane Irma’s effects on the islands on its accounts on Facebook (CaribbeanTourismOrganization) and Twitter (ctotourism).
