How long did the Mabein fire last?

GWIS (Copernicus) dates it between 1 April 2026 and 7 April 2026: 7 days 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 6,037 hectares (60.4 km²). It is an estimate: official national figures may differ.

Which municipalities burned?

The fire only entered Mabein (6,050 ha, 1.2 %).

What was the weather like?

During the fire the temperature reached 40.0 °C, humidity dropped to 21 % and gusts hit 31 km/h. The fire danger index (FWI) reached 37, class High.

Where does this data come from?

From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Myanmar (Burma) (geoBoundaries). It is not an official report.

The fire started on 1 April 2026 in Mabein, Myanmar (Burma), and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,037 hectares from heat detections, spread across a single municipality.

It is the 91th largest in Shan since 2016 (of 723 with a page). Number 88 in Myanmar (Burma) in 2026, of 418.

The power measured by the satellite is low (27.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 ADM3 (Creative Commons Attribution 4.0 (CC BY 4.0)). 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.
