Nova Mamoré fire, 24 August 2022 Nova Mamoré

Out · last detection 27 Aug 2022, 17:29 UTC

The fire started on 24 August 2022 in Nova Mamoré, Brazil, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,197 hectares from heat detections, spread across a single municipality.

It is the 267th largest in Rondônia since 2016 (of 300 with a page). Number 621 in Brazil in 2022, of 687.

It had gone 7 days without rain (1 mm or more) when it started. Rain came after the fire: 1.7 mm on 10 Sept.

This area had burned before

76% of the perimeter overlaps earlier fires recorded since 2016: 184 ha in 2016, 1,107 ha in 2017, 604 ha in 2018, 39 ha in 2019, 1,651 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 2,443 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.
