San José fire, May 2024 San José

Out · last detection 4 Jul 2024, 17:32 UTC

The fire started on 29 May 2024 in San José, Bolivia, and satellites saw it burning for 37 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,533 hectares from heat detections, spread across a single municipality.

It is the 315th largest in Santa Cruz since 2016 (of 784 with a page). Number 123 in Bolivia in 2024, of 295.

It had gone 4 days without rain (1 mm or more) when it started.

This area had burned before

77% of the perimeter overlaps earlier fires recorded since 2016: 104 ha in 2017, 1,869 ha in 2018, 367 ha in 2019, 720 ha in 2020, 2,315 ha in 2022, 4,321 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 5,021 ha that had burned before.

How big is it?

It burned the equivalent of 4.1% of the area of London (65 km² against 1,583 km²).

It was 1.5 times larger than the median of its twins and lasted 37 days, against 14 days.

Only 9 of its 34 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 4 of 34, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.8 mm.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2016.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions

How long did the San José fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 29 May 2024 to 4 July 2024 (37 days). The perimeter dates it from 4 June 2024 to 29 June 2024.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 6,533 hectares (65.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered San José (6,570 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 34.6 °C, humidity dropped to 28 % and gusts hit 64 km/h. The fire danger index (FWI) reached 57, class Extreme.
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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 34. Their median duration was 14 days and their median area 4,305 ha; 18 % went past 10,000 ha. Only 9 of its 34 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 4 of 34, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.8 mm.

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 4 June 2024 to 29 June 2024. 563 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.

How we build fire pages: methodology

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.
