Hasbaya fire, July 2026 Marjaayoun, Hasbaya
The fire started on 24 July 2026 in Hasbaya, Lebanon, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 172 hectares from satellite imagery, spread across 2 municipalities.
It is the 19th largest in Nabatîyé since 2016 (of 38 with a page). Number 9 in Lebanon in 2026, of 17.
The power measured by the satellite is low (20.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started.
This area had burned before
26% of the perimeter overlaps earlier fires recorded since 2016: 44 ha in 2024.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 1.5 hectares of built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions
- How long did the Hasbaya fire last?
- The official perimeter only gives the start date (24 July 2026). The end comes from the heat detections inside the perimeter: it burned until 24 July 2026 (1 day from 24 July 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 172 hectares (1.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Marjaayoun (88 ha, 0.3 %); Hasbaya (84 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 31.2 °C, humidity dropped to 52 % and gusts hit 40 km/h. The fire danger index (FWI) reached 26, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Lebanon (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 11 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Public Domain). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
