Lăpugiu de Jos fire, April 2020 Lăpugiu de Jos, Pietroasa, Dobra
The fire started on 4 April 2020 in Lăpugiu de Jos, Romania, and satellites saw it burning for 10 days. Copernicus mapped a burnt perimeter of 476 hectares from satellite imagery, spread across 3 municipalities.
It is the 6th largest in Hunedoara since 2016 (of 72 with a page). Number 9 in Romania in 2020, of 62.
The power measured by the satellite is low (29.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions
- How long did the Lăpugiu de Jos fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 4 April 2020 to 13 April 2020 (10 days). The perimeter dates it from 6 April 2020 to 7 April 2020.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 476 hectares (4.8 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Lăpugiu de Jos (388 ha, 3.8 %); Pietroasa (86 ha, 0.6 %); Dobra (2 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 16.8 °C, humidity dropped to 14 % and gusts hit 34 km/h. The fire danger index (FWI) reached 10, class Low.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Romania (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.

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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 6 April 2020 to 7 April 2020. 72 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
Where this data comes from
The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. 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 4.0 International (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
