Genasys EVAC tracks and maps U.S. fires with significant activity over the last 10 days. This feature combines multiple active-fire sources into one up-to-date resource.
In EVAC, active incidents will appear as one of two categories: active fires and active fire perimeters.
-
Active Fires: Any fires with significant activity in the past 10 days. This includes smaller fires that are limited to a specific location or area (e.g., a car fire). All ‘Active Fires’ are represented as the ignition points. Fires that are less than 24 hours and contain only one data source are classified as emerging fires. Fires that have a mapped perimeter and/or multiple data sources are classified as a large incident.
-
Active Fire Perimeters: Larger incidents with significant activity in the past 10 days that have been mapped and therefore have an associated fire perimeter.
NOTE: All active fire perimeters will also have an associated active fire icon (latitude and longitude of the ignition).
These layers provide data for fires across the entire continental United States.
Viewing Active Fires and Active Fire Perimeters
To view all active fires and/or active fire perimeters, follow one of the two options below.
Option 1-
Open the Layers section, found in the left side bar. This will open the Layers window.
-
Select the Fire tab.
-
Activate the Active Fires and/or Active Fire Perimeters sliders to show the fires on the EVAC map. Active fires are represented by fire icons and active fire perimeters are represented by red plots.
Option 2
- Click on the Fires button in the left side bar. This will open the Fires window.
- Activate the Ignitions and/or Perimeters sliders in the top right to show the fires on the EVAC map. Active fires are represented by fire icons and active fire perimeters are represented by red plots.
Incident Details
For more information about an active incident, click on the associated fire icon. This will open a pop-up window with available details about the fire.
The data for the incidents is curated from a number of different sources. The specific Data Sources for a particular fire will be listed in the Details pop-up.
