About Google Crisis Map
We created the Google Crisis Map (google.org/crisismap) to help people find and use critical emergency information when they need it most. Using Google's technology, speed, and user-friendly design, Crisis Map was designed to make disaster information easy to find, use, and share.
The online maps include the latest satellite imagery and available information like storm paths, flood zones, evacuation routes, shelter locations, and power outages.
- See data in a simple map format on a range of browsers and devices. Quickly access important information about a crisis situation and explore the information visually on an easy-to-use map, optimized for both mobile and desktop screens.
Find information in one place. Crisis Map collects information that's normally scattered across the Web and other resources and makes it easily available through a single map. Find authoritative information as well as crowd-sourced data, all in one place.
Depend on the latest information. Crisis Map always shows the latest information that is available to us. Because it's grounded in Google Maps technology, Crisis Map is fast, reliable, and ready to handle large numbers of visitors during an event.
Using the map
1. Get started by visiting google.org/crisismap.
2. Choose a map: The large red text at the top shows you which map is showing. Choose a different map using the drop-down arrow right next to the map name, or enter a location in the white box within the map itself.
3. Choose information to show: Check the box next to each layer that you'd like to see on the map, such as "Public Alerts" or "US Storm Reports." Check the box again to remove that information from your map. You can hide the panel of layers by clicking the arrow at the top right of the page.
Here's more detail on what you can do with Crisis Map:
Finding detailed information
- About the layer: When you select a layer, additional details about it and its information will appear, such as a description, link to the data provider's website, or a map legend for that particular layer. Some layers include settings so you can adjust the layer's transparency or make other adjustments.
- Zoom: There are a few ways to hone in on a specific area of the map:
- For certain layers, click the "Zoom to area" link below the layer name to focus the map around on the area that has information shown in that layer.
- Enter a location like a city name or zip code into the white search box on the map.
- Use the zoom slider at the bottom corner of the map.
- Map markers: If a layer shows placemarks, lines, or shapes on the map, clicking on those markers within the map will show more information about that particular location or event.
Seeing maps on your mobile device
- Devices: You can see disaster maps on your mobile phone, tablet, desktop computer, or laptop. Maps are automatically adjusted to work well on smaller screens.
- Layers: To see the list of data layers on a mobile device, click the "Layers" button on the map. To close the list and return to the map, click the "X" at the top of the list.
Sharing a customized map
Click the "Share" button at the top of the map to see these sharing options:
- Link: Copy the link to send someone the exact map you're looking at, including the specific layers you've selected and the area you've zoomed in on.
Embed: Share your view of the map by inserting it into your own website, blog, or other page. Just add the snippet of HTML code provided into the code of your website.
Share: Use the Google+, Twitter, and Facebook buttons to share your map through those channels.
Google Earth: You can view some layers in Google Earth by clicking the "Download KML" link beneath the layer's name.
