East Ujimqin Banner fire, 19 April 2022 China

Out · last measured on 19 Apr 2022

The fire started on 19 April 2022 in East Ujimqin Banner, China, and satellites saw it burning for 1 day. Copernicus’s global GWIS system rebuilt a burnt perimeter of 12,415 hectares from heat detections, spread across a single municipality.

It is the 8th largest in Inner Mongolia Autonomous Region since 2016 (of 370 with a page). The largest in China in 2022, of 241.

We have the GWIS perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Frequently asked questions

How long did the East Ujimqin Banner fire last?
GWIS (Copernicus) dates it between 19 April 2022 and 19 April 2022: 1 day between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 12,415 hectares (124.2 km²). It is an estimate: official national figures may differ.
What was the weather like?
During the fire the temperature reached 21.1 °C, humidity dropped to 15 % and gusts hit 48 km/h. The fire danger index (FWI) reached 18, class Moderate.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of China (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.

Emergency number: 119

Satellite cross-check

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 119.

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 (Open Data Commons Open Database License 1.0). 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.
