San Miguel fire, June 2022 San Miguel
The fire started on 12 June 2022 in San Miguel, Bolivia, and satellites saw it burning for 30 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,749 hectares from heat detections, spread across a single municipality.
It is the 612th largest in Santa Cruz since 2016 (of 837 with a page). Number 161 in Bolivia in 2022, of 222.

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 2 days without rain (1 mm or more) when it started. Rain came after the fire: 2.1 mm on 12 Jul.
This area had burned before
80% of the perimeter overlaps earlier fires recorded since 2016: 8 ha in 2016, 735 ha in 2017, 632 ha in 2018, 3,568 ha in 2019, 1,378 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 2,997 ha that had burned before.

What happened to each town
-
3,763 ha reached on 12 Jun0.4 %
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 was no noticeable built-up land and almost nobody lived there (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 San Miguel fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 12 June 2022 to 11 July 2022 (30 days). The perimeter dates it from 12 June 2022 to 4 July 2022.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,749 hectares (37.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered San Miguel (3,763 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 33.0 °C, humidity dropped to 25 % and gusts hit 57 km/h. The fire danger index (FWI) reached 28, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Bolivia (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 adjusted with the VIIRS detections inside the perimeter, which said 12 June 2022 to 4 July 2022. 323 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 ADM3 (Public Domain). 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.
