   LONDON (AP) -- Wildfires fueled by climate change have ravaged communities 
from Maui to the Mediterranean this summer, killing many people, exhausting 
firefighters and fueling demand for new solutions. Enter artificial 

   Firefighters and startups are using AI-enabled cameras to scan the horizon 
for signs of smoke. A German company is building a constellation of satellites 
to detect fires from space. And Microsoft is using AI models to predict where 
the next blaze could be sparked.

   With wildfires becoming larger and more intense as the world warms, 
firefighters, utilities and governments are scrambling to get ahead of the 
flames by tapping into the latest AI technology -- which has stirred both fear 
and excitement for its potential to transform life. While increasingly 
stretched first responders hope AI offers them a leg up, humans are still 
needed to check that the tech is accurate.

   California's main firefighting agency this summer started testing an AI 
system that looks for smoke from more than 1,000 mountaintop camera feeds and 
is now expanding it statewide.

   The system is designed to find "abnormalities" and alert emergency command 
centers, where staffers will confirm whether it's indeed smoke or something 
else in the air.

   "The beauty of this is that it immediately pops up on the screen and those 
dispatchers or call takers are able to interrogate that screen" and determine 
whether to send a crew, said Phillip SeLegue, staff chief of intelligence for 
the California Department of Forestry and Fire Protection.

   The cameras, part of a network that workers previously had to watch, provide 
billions of bytes of data for the AI system to digest. While humans still need 
to confirm any smoke sightings, the system helps reduce fatigue among staffers 
typically monitoring multiple screens and cameras, alerting them to look only 
when there's possible fire or smoke, SeLegue said.

   It's already helped. A battalion chief got a smoke alert in the middle of 
the night, confirmed it on his cellphone and called a command center in San 
Diego to scramble first responders to the remote area.

   The dispatchers said that if they hadn't been alerted, the fire would have 
been much larger because it likely wouldn't have been noticed until the next 
morning, SeLegue said.

   San Francisco startup Pano AI takes a similar approach, mounting cameras on 
cell towers that scan for smoke and alert customers, including fire 
departments, utility companies and ski resorts.

   The cameras use computer vision machine learning, a type of AI.

   "They're trained very specifically to detect smoke or not, and we train them 
with images of smoke and images of not smoke," CEO Sonia Kastner said.

   The images are combined with feeds from government weather satellites that 
scan for hotspots, along with other data sources, such as social media posts.

   The technology gets around one of the main problems in the traditional way 
of detecting wildfires -- relying on 911 calls from passers-by that need 
confirmation from staffers before crews and water-dropping planes can be 

   "Generally, only one in 20 of these 911 calls are actually a wildfire. Even 
during fire season, it might be a cloud or fog or a barbecue," Kastner said.

   Pano AI's systems do still rely on final confirmation, with managers playing 
a time lapse of the camera feed to ensure it's smoke rising.

   For fighting forest fires, "technology is becoming really essential," said 
Larry Bekkedahl, senior vice president of energy delivery at Portland General 
Electric, Oregon's largest utility and a Pano AI customer.

   Utility companies sometimes play a role in sparking wildfires, when their 
power lines are knocked down by wind or struck by falling trees. Hawaii's 
electric utility acknowledged that its power lines started a devastating blaze 
in Maui this summer after apparently being downed by high winds.

   PGE, which provides electricity to 51 cities in Oregon, has deployed 26 Pano 
AI cameras, and Bekkedahl said they have helped speed up response and 
coordination with emergency services.

   Previously, fire departments were "running around looking for stuff and not 
even really knowing exactly where it's at," he said. The cameras help detect 
fires quicker and get teams on the ground faster, shaving up to two hours off 
response times.

   "That's significant in terms of how fast that fire can can spread and grow," 
Bekkedahl said.

   Using AI to detect smoke from fires "is relatively easy," said Juan Lavista 
Ferres, chief data scientist at Microsoft.

   "What is not easy is to have enough cameras that cover enough places," he 
said, pointing to vast, remote areas in northern Canada that have burned this 

   Ferres' team at Microsoft has been developing AI models to predict where 
fires are likely to start. They have fed the model with maps of areas that 
burned previously, along with climate and geospatial data.

   The system has its limitations -- it can't predict random events like a 
lightning strike. But it can sift through historical weather and climate data 
to identify patterns, such as areas that are typically drier. Even a road, 
which indicates people are nearby, is a risk factor, Ferres said.

   "It's not going to get it all perfectly right," he said. "But what it can do 
is it can build a probability map (based on) what happened in the past."

   The technology, which Microsoft plans to offer as an open source tool, can 
help first responders trying to figure out where to focus their limited 
resources, Ferres said.

   Another company is looking to the heavens for a solution. German startup 
OroraTech analyzes satellite images with artificial intelligence.

   Taking advantage of advances in camera, satellite and AI technology, 
OroraTech has launched two mini satellites about the size of a shoebox into low 
orbit, about 550 kilometers (340 miles) above Earth's surface. The Munich-based 
company has ambitions to send up eight more next year and eventually put 100 
into space.

   As wildfires swept central Chile this year, OroraTech said it provided 
thermal images at night when aerial drones are used less frequently.

   Weeks after OroraTech launched its second satellite, it detected a fire near 
the community of Keg River in northern Alberta, where flames burned remote 
stretches of boreal forest repeatedly this summer.

   "There are algorithms on the satellite, very efficient ones to detect fires 
even faster," CEO Thomas Gruebler said.

   The AI also takes into account vegetation and humidity levels to identify 
flare-ups that could spawn devastating megafires. The technology could help 
thinly stretched firefighting agencies direct resources to blazes with the 
potential to cause the most damage.

   "Because we know exactly where the fires are, we can see how the fires will 
propagate," Gruebler said. "So, which fire will be the big fire in one day and 
which will stop on their own."
