Every fire on Earth, updated every hour
Aursee is a live map of the fires burning around the world. Three
satellites carrying the VIIRS instrument — Suomi NPP, NOAA-20 and
NOAA-21 — record hot spots 375 metres across each time they pass
overhead, about twice a day each. Every hour we take the last full 24 hours
of detections from NASA FIRMS, join neighbouring detections into fires, name
each one after the nearest town, and put them on the globe above.
Right now 25,689 fires detected in the last 24 hours across 147 countries · VIIRS 375 m · updated 2026-11-02 03:24 UTC

What you can do here
See today’s fires by country , ranked by
radiative power, with a page for the largest.Open a fire for where and when it was first seen, how many detections
it is made of, the wind it is burning in, the land cover under it, and how
often that ground has burned since 2012.
Check a destination before you travel: fires
nearby, sea temperature, UV and bathing water.Get an email when fire is detected near a place
you choose, and when it clears.Look back: fire history by country for every
year since 2012, and the largest fires we have
recorded.
How to read it
A detection is heat seen from orbit at the moment of a pass. Cloud,
thick smoke and the hours between passes mean some fires are not seen, and
a small fire can light a whole pixel. Each figure on the site carries its
instrument and resolution, and every rule we apply is written out on the
method pages : how detections are
grouped into fires , what
radiative power measures, and what the
burn archive counts.

Every fire on Earth, and whether it makes sense
Satellites have been able to see fire from orbit for twenty
years. What nobody has built is the thing that reads them: an instrument that
takes thirty thousand fires a day and tells you which ones behave like fire,
and which ones behave like somebody.
What you get for every single fire
Click any dot on the globe. Not a popup with a coordinate — a file.
These are drawn live, from the fire currently burning hardest on Earth.
How it spread Every 375 m detection the fire is
made of, placed in metres and coloured by the hour it arrived. A fire
that walked shows a walk. One that arrived everywhere at once shows
that too.
Where the wind takes it Speed and direction at the
moment it was lit, and again six and twelve hours out. Smoke and embers
go where the arrows point.
When the satellite first saw it In local solar time,
against every other fire within 300 km. VIIRS passes about 01:30
and 13:30, so a first detection places the start inside the preceding
twelve hours.
What this ground has done before One mark per day for
this exact patch of earth, going back through fourteen years of archive.
You can see at a glance whether today is its normal August or something
it has never done.
And the rest of the file
Satellite film of it burning. Geostationary imagery over the
fire, ten minutes a frame, for the hours it was alight — switching to
infrared at night, because the fires worth noticing burn in the dark.The nearest town, by name. Bearing, distance, and how many
people live within 25 km. Every settlement in the feed carries its
name, so the map answers in places rather than coordinates.When it started — in UTC and in local solar time, which is
the one that tells you whether anyone was working.How big and how hot — radiative power, hottest pixel,
extent, and the share caught on the night pass.Its neighbours. How many fires within 10 km, and how many
of those began within the same hour.Its standing. The 9th largest fire burning on Earth right
now, 3rd of 25 within 200 km. Numbers you can hold.Next satellite look. The orbit is sun-synchronous, so the next
pass over that exact ground is a known hour and we name it.Where analysis would go. Every hour, every detection on Earth is
screened for the shapes that matter — events too far apart to be one
fire and too close to be strangers, activity compressed into a burst,
ignitions at hours nobody works. You see the score and the reasons.
Watch one, and we will tell you
Keep a fire and we write to you when it stops, restarts, grows sharply, or
is still burning after dark . Or keep a place — thirty
kilometres around your town — and hear when anything appears in it. One
email per change, or one a day. Your choice, changed in a click, stopped in
one press.
How it knows
VIIRS at 375 m , three satellites, twice a day over every
point on Earth. Fires reach the page about three hours after the satellite
sees them.Geostationary imagery every ten minutes — GOES over the
Americas, Meteosat over Europe and Africa, Himawari over Asia-Pacific.Fourteen years of burn history , back to January 2012, at
one-kilometre resolution. That is what lets the page say this ground has
never burned before.Live weather at every fire, from a model we run ourselves.Published method. The null models and the code are open, and the
calibration numbers are published including the ones that do not flatter
us. An arson claim nobody can reproduce is just an opinion.
Nobody else does this
Every fire map on the internet shows you where fires are. Ask any of them
why and they copy a line from the fire service: Cause: under investigation . There is no public tool
that reads the pattern itself. That is the whole of what we built.
What we hold about you
The map opens without an account. Make one, to be told when a fire
changes, and this is the whole of it: your email address , used to
write to you and handed on only to the relay that delivers the mail;
the fires and places you chose to watch ; and anything you
upload , with the camera's own GPS and serial number stripped out before
it is stored. Signing in is a link that works once, for thirty minutes.
Pictures in our emails travel inside the message. Delete my account
erases the address, the watch list, the queued mail and your files from the
disk.
Every figure carries its instrument, resolution and error bar, and is marked
detected , derived or inferred . Where a test could not
run, the page says so.contact@aursee.org
