<br>
Yes, you can get NRT data from here:<br>
<a href="https://firms.modaps.eosdis.nasa.gov/active_fire/" rel="noreferrer" target="_blank">https://firms.modaps.eosdis.nasa.gov/active_fire/</a><br>
- Shapefiles<br>
- Google Earth KML<br>
- Text Files (CSV)<br>
<br>
This you may import (v.import) and visualize/analyse.<br>
<br>
Best wishes,<br>
