Mazzarino fire, 18 July 2026 Mazzarino

Out · last detection 21 Jul 2026, 01:26 UTC

The fire started on 18 July 2026 in Mazzarino, Italy, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 266 hectares from satellite imagery, spread across a single municipality.

It is the 38th largest in Caltanissetta since 2016 (of 149 with a page). Number 81 in Italy in 2026, of 232.

The power measured by the satellite is low (9.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 11 days without rain (1 mm or more) when it started. Rain came after the fire: 8.1 mm on 28 Jul.

This area had burned before

47% of the perimeter overlaps earlier fires recorded since 2016: 1 ha in 2019, 66 ha in 2020, 17 ha in 2021, 5 ha in 2022, 49 ha in 2023, 1 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 124 ha that had burned before.

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.

Frequently asked questions

How long did the Mazzarino fire last?
The official perimeter only gives the start date (20 July 2026). The end comes from the heat detections inside the perimeter: it burned until 21 July 2026 (4 days from 18 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 266 hectares (2.7 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Mazzarino (266 ha, 0.9 %).
Did the fire reach a town?
The fire started in Mazzarino and came within 16.8 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 44.7 °C, humidity dropped to 8 % and gusts hit 33 km/h. The fire danger index (FWI) reached 69, class Extreme.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Italy (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. 15 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.

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 ADM4 (Creative Commons Attribution 3.0 License). 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.
