If there’s an active crisis in your current map view, you may find an alert with updates and safety information about the event. Active crises include wildfires, floods and earthquakes.
Crisis-related alerts show up on your map if:
- You search for an area including a wildfire and are at the correct zoom level
- You select a navigation route that enters an area impacted by a crisis
Use the crisis sheet
In the alert, tap the crisis icon or alert card to expand the crisis sheet.
The sheet may also reveal more information, updates and news articles related to the crisis.

Understand crisis-related alerts
Alerts make emergency information from local, national or international authorities easily accessible during a crisis. You can find that information highlighted on Google Maps. Examples of crisis information include emergency phone numbers, websites or map visualisations for a detailed view.
Google Maps shows alerts for these natural disasters:
- Earthquakes
- Floods
- Hurricanes or typhoons
- Tropical storms
- Wildfires
Get information about active wildfires
There are different ways to find information about active wildfires on your map:
- Turn on the Wildfires layer: Tap Layers
the Wildfires button.
- Search for the fire: Enter a fire-related query into the Google Maps search box, such as 'wildfires' or the name of an individual fire. Tap the result to show the layer.
- Tap the fire alert banner: If an active fire’s location overlaps with the visible part of your map, a fire alert banner shows up in the Explore sheet on the Maps homescreen. Tap the banner to turn on the layer.
the Wildfires button.On your map, wildfires can be represented by:
- The wildfires icon
or a tiny red circle
- A red shape representing an approximate area impacted by a wildfire
Get additional information
When available, we provide more information related to a specific incident. This information is listed on the crisis sheet associated with the fire and may include:
- Help and information from local authorities
- News headlines
- Containment information
To open the crisis info sheet, tap the fire icon on the map.
Google Maps uses several sources to compile data for the Wildfires layer.
- Google 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. Learn more about SOS Alerts.
- Google Public Alerts: Google Public Alerts provide access to trusted safety information directly from authorities around the world. Learn more about who provides content to Public Alerts.
- National Interagency Fire Centre (NIFC): Many of the fires in this layer are provided by NIFC via Wildland Fire Interagency Geospatial Services (WFIGS). These fires are represented by a point on the map and indicate the reported point of fire origin. Some of these fires may be labelled 'planned fire', also known as a prescribed fire or a controlled burn, which are used to manage forests and prevent wildfires. Fires under five acres are not shown.
For some fires, you'll see a red outline. This represents the approximate area impacted by the fire. Learn more about boundary maps.
Google also gathers data from:
- National Oceanic and Atmospheric Administration (NOAA)
- National Meteorological Satellite Centre (NMSC)
- Japan Meteorological Agency (JMA)
Google Maps wildfires information is approximate. The outline of an actual fire may differ by several miles from its representation on Maps. Check official sources for real-world conditions.
What data do we use to generate fire alerts?
To generate fire alerts, we apply a deep learning model to track the extent of fires from real-time satellite imagery. The model is based on superresolution image fusion of hyperspectral imagery from third-party satellites, which includes:
- GOES-16 and GOES-18
- GK2A
- Himawari-9
- Meteosat-9 and Meteosat-11 from EUMETSAT [2023]
- Aqua and Terra with MODIS imager
- S-NPP, JPSS-1 with VIIRS imager
