Park Ou fire, 31 March 2016 Park Ou, Nga

Out · last detection 15 Apr 2016, 05:41 UTC

The fire started on 31 March 2016 in Park Ou, Laos, and satellites saw it burning for 16 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,628 hectares from heat detections, spread across 2 municipalities.

It is the 61th largest in Luang Prabang since 2016 (of 293 with a page). Number 26 in Laos in 2016, of 143.

Frequently asked questions

How long did the Park Ou fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 31 March 2016 to 15 April 2016 (16 days). The perimeter dates it from 1 April 2016 to 8 April 2016.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,628 hectares (46.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Park Ou (2,856 ha, 3.2 %); Nga (1,797 ha, 0.9 %).
What was the weather like?
During the fire the temperature reached 37.4 °C, humidity dropped to 28 % and gusts hit 44 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 Laos (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.

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.

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.
