Manyoni fire, June 2024 Manyoni

Out · last detection 16 Jun 2024, 22:31 UTC

The fire started on 10 June 2024 in Manyoni, Tanzania, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,779 hectares from heat detections, spread across a single municipality.

It is the 81th largest in Singida since 2016 (of 124 with a page). Number 43 in Tanzania in 2024, of 70.

The power measured by the satellite is low (20.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

This area had burned before

85% of the perimeter overlaps earlier fires recorded since 2016: 2,461 ha in 2017, 250 ha in 2019, 1,881 ha in 2020, 421 ha in 2021, 592 ha in 2022, 465 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 3,219 ha that had burned before.

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.

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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
