SOS Alerts FAQs

1. What are SOS Alerts?

   SOS Alerts aim to make emergency information more accessible during a crisis. We bring together relevant and authoritative content from the web, social media, and Google products, and then highlight that information on Google products such as Search and Maps. Depending on the nature of the crisis and your location, you’ll see updates from local, national, or international authorities. These updates could include emergency phone numbers and websites, maps, translations of useful phrases, donation opportunities, and more.

2. How does Google decide when to show an SOS Alert?

   We look at a number of factors, such as internet connectivity in the affected area, the availability of official content from governments and other authoritative organizations, and the impact on the ground. SOS Alerts are typically available in the primary languages of the affected area, as well as English.  

   While we can’t guarantee that you’ll see an SOS Alert for every major crisis, we aim to make them available more broadly over time. Please tap the Feedback link on any SOS Alert if you have suggestions on how we can improve. We’d appreciate your input.

3. Where do you get the content for SOS Alerts?

   We have teams around the world who source content from government agencies, first responders, trusted media outlets, and NGOs. We also aggregate information from other Google products and services, such as Google News, Google Maps, Waze, and more.

4. How can I get an SOS Alert?

   If you’re near a major crisis and you search for related words or phrases on Google, you may see a banner indicating that there’s an ongoing crisis, followed by emergency information and resources such as useful translations or phone numbers. If you’ve installed the latest version of the Google app (Android and iOS) and your location is turned on, you may also receive a notification on your mobile device’s home screen. Tap the notification to see the full alert on Google Search. 

   If you’re outside the crisis area, you won’t get a notification, but you can still find SOS Alerts by searching for information about the event. The information you get may be different from what people closer to the crisis area see. For example, instead of seeing emergency phone numbers, you may see a link to make a donation for that crisis. 

   If you’re using Google Maps, you may also see SOS Alerts right on the map if any alerts are active in the area you’re viewing. Tap on the icon to get more information about the crisis, such as helpful phone numbers and websites.

5. Why don’t I see any SOS Alerts?

   If you don’t see an SOS Alert during a crisis, it may be due to one of these reasons:

   • Your search query may be too broad. Try searching for keywords that include both the type of disaster and the name of the affected area. 
   • We may still be gathering and verifying information prior to launching an SOS Alert. Check back again for updates as the crisis evolves. 
   • We may not have plans to launch an SOS Alert for this emergency. We aim to make SOS Alerts available for more crises. To learn how we support crisis efforts, like awarding grants and providing volunteer opportunities, visit Crisis Response.

6. How can I provide feedback on the content in an SOS Alert?

   Tap the Feedback link at the top of the alert to let us know how we’re doing. We’ll review your comments or suggestions as soon as possible. 

7. I have a question about making a donation.

2. How do the Flood Forecasting models work?

   To provide Flood Forecasting, we monitor historical and real-time water level measurements and precipitation forecasts. We use data that’s either publicly available or available to Google through partnerships with local governments. Based on this information, we run 2 main types of machine learning models:

   • Hydrologic models: Provides forecasts of river water levels for upcoming days.
   • Inundation models: Provides forecasts for the flood extent on the ground. This information tells us who to notify and helps us provide flood maps on Google Maps.

   Find more information about these models.

3. How does Google decide when to show a Flood Forecasting alert?

   Google displays a Flood Forecasting alert when the water in a river is higher than a warning level or is expected to be higher than a warning level. Warning levels estimate when a river will flood and are usually based on historical flood events. Government agencies that manage floods provide warning levels to Google.

   Google Flood Forecasting alerts are updated several times a day, based on real-time local data. If an alert is no longer active, Google removes it from Search and Maps results.

    

4. Who receives Flood Forecasting notifications?

   Once an upcoming flood is identified, Google sends notifications. Notifications go to people who have their smartphone location services turned on and who are located in the area that’s flooded or expected to flood. If you aren’t near an area that’s flooded or expected to flood, you won’t get a Google flood forecast notification.

5. Turn off Flood Forecasting notifications

   You’ll find Flood Forecasting notifications as part of the Google Search Application notifications. On Android devices, it’s available as a system app. On iPhones and iPads, you can install the Google app from the Apple App Store.

   To turn off Flood Forecasting notifications, turn off “Crisis Alerts” notifications.

   If you are within a supported area, and search for a flooded area in a specific location via google search app, you’ll find a flood forecast in your Search page results. If your location services are turned on and you search for floods without a location specified, you’ll see a flood forecast if there’s flooding near you.

6. When I search for “flood,” why don’t I always get a Flood Forecasting alert?

   Your Search results depend on location. If you search for flood and include a specific location that’s flooded, you’ll find a flood forecasting alert in your results. If your location services are turned on and you search for flood without a location specified, you’ll get an alert only if there’s flooding near you.

7. Do Google’s Flood Forecasting alerts coordinate with local governmental alerts?

   Google partners with the relevant government agencies in charge of flood monitoring and alerting. This ensures that Google displays alerts in coordination with governmental alerts that are released in other ways.
