California Wildfire Roundup

The San Francisco Chronicle’s 2018 California Fire Tracker is an interactive map of ongoing and contained wildfires—notably, at this moment, the Camp and Woolsey fires. It includes fire perimeter and air quality data. (Note: it’s glitchy on desktop Safari.)

Two Esri maps: a general wildfire map and a map of smoke from wildfires [Maps Mania]. Add to that a map of field damage reports in the area hit by the Camp Fire [Maps Mania].

NASA/JPL-Caltech

The Jet Propulsion Laboratory has produced a map of the damage from the Camp Fire based on satellite radar images. NASA Earth Observatory has maps and animations showing the impact of the Camp Fire on air quality and satellite images of the Woolsey Fire burn scar.

NOAA

The New York Times has a map tracking air quality in California. Smoke from the fires has reached the east coast: an outcome predicted by atmospheric models (see above map).

This interactive map from NBC News that superimposes the Camp Fire on any location to help people outside California get a sense of how big these fires are. [Maps Mania]

Carbon Monoxide from the California Wildfires

Carbon monoxide released into the atmosphere by the California wildfires is drifting across North America in concentrations sufficient to turn up on the Atmospheric Infrared Sounder (AIRS) on NASA’s Aqua satellite. A series of maps showing CO concentrations in the United States between 30 July and 7 August, using AIRS data, have been combined into the animation above.

Mapping the British Columbia Wildfires

British Columbia isn’t having a very good year either, forest fire wise. For maps of the wildfires burning in the province, see the B.C. Wildfire Service’s interactive map, which shows active wildfires, fire perimeters, and evacuation areas. Evacuation maps are frequently tweeted by Emergency Info BC. Data journalist Tara Carman has posted maps of wildfires and evacuation zones, but they haven’t been updated in a couple of weeks and are now out of date, I fear.

The Washington Post maps the largest of the wildfires burning in northern California: the Carr Fire threatening the city of Redding and surrounding communities. The Redding Record Searchlight has drone footage of the destruction wreaked by the Carr Fire in Shasta County. NASA has natural and false-colour imagery (Earth Observatory, Visible Earth) of the Carr Fire, as well as the Ranch and River Fires to the south, the so-called Mendocino Complex. See the Mercury News’s fire map of the Mendocino Complex, whose two fires’ combined acreage is now larger than the Carr Fire. Meanwhile, German astronaut Alexander Gerst observed the California wildfires from the International Space Station. [San Francisco Chronicle]

U.S. Wildfire Causes, 1980-2016

Jill Hubley has mapped the causes of wildfires in the United States from 1980 to 2016, based on Federal Wildland Fire Occurrence Data. The map toggles between main causes (human and natural) and specific cause; there’s also a chart ranking the causes.

The highest and lowest ranked causes are highlighted when the chart loads. These represent the cumulative ranking across all years. Lightning, a natural cause, often floats to the top, but that’s only because on the human side, the vote is split between more than twenty options. Lightning doesn’t predominate in all states, though. In Alabama, the number one cause is pyromania. In Indiana, it’s brakeshoes. In Minnesota, it’s field burning. There are a couple of overall trends, too. Smoking is going down as a cause, and powerlines are going up.

How to Build a Fire Map

Last October Robin Kraft posted an online map of the northern California wildfires showing satellite imagery from before and after the fires (see previous entry); today he’s posted a blog entry explaining how he built it, in great technical detail. The timing is not accidental: “There is another fire raging in Los Angeles right now — if DigitalGlobe and Planet release their data, you can use this guide to make your own map.”

California Wildfires: Mapping Sonoma County

Sonoma County’s wildfire information page points to a number of useful maps: fire perimeter boundary maps, current evacuation areas, road closures, rapid evaluation safety assessment (RESA) maps. The City of Santa Rosa’s emergency information page also has maps specific to that city; Heavy also has a roundup. See also Cal Fire’s structural status information map. [The Mercury News]

Maps and satellite imagery of the wildfires in Northern California include the San Francisco Chronicle’s interactive map; Robin Kraft’s interactive map  showing satellite imagery from before and after the fire; this New York Times page mapping building damage in Santa Rosa; the Washington Post’s coverage of the devastation; and NASA Earth Observatory’s images of the smoke plumes here and here.

Satellite Imagery of Fort McMurray Wildfire Damage

Satellite imagery from the Pléiades-1A satellite showing the extent of wildfire damage caused to Fort McMurray, Alberta can be viewed through a web-based mapping application released by the government of Alberta. (Doesn’t work in Safari for Mac; works fine in Chrome.) [CBC News]

DigitalGlobe Satellite Imagery of Fort McMurray

DigitalGlobe’s satellite imagery of the Fort McMurray wildfire, which uses “short wave infrared imagery (SWIR) to ‘cut’ through the smoke and identify the active footprint and burning hotspots” and reveals where buildings have been damaged or destroyed by the fire, can be viewed at Gizmodo and on DigitalGlobe’s own blog.
