Benjamín Aceval fire, 15 April 2020 Benjamín Aceval, José Falcón, General Jose Maria Bruguez
The fire started on 15 April 2020 in Benjamín Aceval, Paraguay, and satellites saw it burning for 14 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,113 hectares from heat detections, spread across 3 municipalities.
It is the 78th largest in PRESIDENTE HAYES since 2016 (of 738 with a page). Number 53 in Paraguay in 2020, of 424.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 2.0 mm on 2 May.
This area had burned before
27% of the perimeter overlaps earlier fires recorded since 2016: 315 ha in 2016, 1,347 ha in 2017, 10 ha in 2018, 161 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 1,624 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS 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 2020Inside the perimeter there were about 0.30 hectares of built-up land and about 20 residents (GHSL 2020, 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.

Frequently asked questions
- How long did the Benjamín Aceval fire last?
- GWIS (Copernicus) dates it between 15 April 2020 and 28 April 2020: 14 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 6,113 hectares (61.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Benjamín Aceval (5,806 ha, 0.5 %); José Falcón (203 ha, 0.1 %); General Jose Maria Bruguez (139 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 36.4 °C, humidity dropped to 29 % and gusts hit 50 km/h. The fire danger index (FWI) reached 37, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Paraguay (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: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 179 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 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. 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 (Creative Commons Attribution 4.0 (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
