Manyoni fire, October 2022 Manyoni

Out · last detection 22 Oct 2022, 11:34 UTC

The fire started on 8 October 2022 in Manyoni, Tanzania, and satellites saw it burning for 14 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,712 hectares from heat detections, spread across a single municipality.

It is the 26th largest in Singida since 2016 (of 124 with a page). Number 12 in Tanzania in 2022, of 71.

The power measured by the satellite is low (25.9 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

69% of the perimeter overlaps earlier fires recorded since 2016: 2,439 ha in 2016, 1,903 ha in 2017, 1,145 ha in 2018, 1,722 ha in 2020, 802 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 4,610 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

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.
