Memorial Fire, May 2019 Berkeley

Out · last detection 27 May 2019, 18:56 UTC

The fire started on 26 May 2019 in Berkeley, United States, and satellites saw it burning for 1 day. United States agencies (MTBS / NIFC) mapped an official burnt perimeter of 688 hectares, spread across a single county.

It is the 6th largest in South Carolina since 2016 (of 14 with a page). Number 266 in United States in 2019, of 367.

The power measured by the satellite is low (23.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 12 days without rain (1 mm or more) when it started. Rain came after the fire: 7.2 mm on 31 May.

This area had burned before

5% of the perimeter overlaps earlier fires recorded since 2016: 12 ha in 2016, 19 ha in 2017, 8 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 31 ha that had burned before.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions

How long did the Memorial fire last?
It burned between 26 May 2019 and 26 May 2019: 1 day, according to the start date recorded by United States agencies (MTBS / NIFC) and the heat detections seen by satellite.
How much area did it burn?
The official perimeter published by United States agencies (MTBS / NIFC) is 688 hectares (6.9 km²). Other tallies, such as daily incident reports, may give slightly different figures.
Which counties burned?
The fire only entered Berkeley (687 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 35.9 °C, humidity dropped to 32 % and gusts hit 33 km/h. The fire danger index (FWI) reached 26, class High.
Where does this data come from?
From the official burnt perimeter of United States agencies (MTBS / NIFC, public domain), NASA FIRMS VIIRS hotspots and the administrative boundaries of United States. 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: 911

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 is official and in the public domain. For past years it comes from MTBS (Monitoring Trends in Burn Severity), run by the U.S. Geological Survey and the USDA Forest Service, which map it on Landsat and Sentinel-2 imagery. For the current and last year it comes from WFIGS at the National Interagency Fire Center (NIFC): incident perimeters mapped by fire crews, aircraft and imagery. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. County boundaries come from geoBoundaries ADM2 (Public Domain). The area per county is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from official figures.
