The most complex and important parts of our city are below our animal foot . If thing go right , we never even point out the slurred stratum cake of cables , pipe , insulant , and refuse that are packed decently under the sidewalk . But in London yesterday and today , the city develop a smokey reminder .

AsGizmodo UK report , a massive electrical fervor — possibly fed by a gas leak — erupted in London yesterday afternoon . Because of the nature of the fire , firefighters were forced to let sunburn for 24 hours , accord to the BBC , and thousands of London resident were evacuated while emergency crew sprayed down buildings nearby the manhole covers that were spitting flames into the street . Why ? Because it was safe than trying to stop the ardour itself , which may have led to an explosion .
As a spokesperson toldThe London Evening Standard,“it ’s safer for us to allow the fire to persist in while we play with the public-service corporation company to isolate and cap the briny . You may see flaming fall up from the ground but that ’s a safer style of dealing with it . ”

Why Manhole Fires Are Increasing
Thankfully , no one was hurt in the flack , and the urban center now enunciate the brilliance is under control . But it ’s a monitor that aging base is becoming a bigger problem than ever in our cities . About a month ago , Reuters published a report on the mature problems here in New York , where in a individual week in February ConEd reported 600 fires in manholes . Reuters say there ’s an average of six manhole incident a day in NYC .

There are plenty of reason why blast in the electric systems just below street level are growing more and more common . The weather does n’t help : Street Strategic Arms Limitation Talks , bum , and construction mistakescan penetrate insularism and sparkle fires . A individual cable television service can carry many 1000 of volt — the corroded cables make small fires and smoke , which ramp up up until the manhole explode with incredible and dangerous military unit .
It ’s just another instance of how urban base , some of it set up in the early years of the 20th 100 , is literally fraying at the ends . But it ’s one of the most pressing , and one of the most difficult to imagine resolution , since replacing every cable housing on every urban center street is impossible .
How Machine Learning Could Help
So , does this mean that NYC , London , and other aging city need to interchange thousands of miles of cabling under their busy streets ? In some places , yes . ButReuters point outthat researchers are go on alternatives , too .
A few years ago , a team at MIT and Columbia set out to use auto learning to figure out where and when these manhole fire would take place in NYC . They used data point mining to rend information about the eld and exposure of ConEd ’s cabling and manholes ( of which there are 51,000 ! ) recorded on “ tickets ” by the ship’s company . The scientists were able-bodied to parse these information into an algorithm that could predict where the next explosions or flak were likely to come .
“ We started this project with a large amount of disparate , noisy ( and at the time , unintelligible ) data , with no warrant or clear indicant that this data could be useful for prediction , and a murky finish of promise ‘ serious ’ events , ” compose the authors in astudy about the undertaking . But they were capable to form a prognostic model that has already been implemented in Brooklyn — to “ excellent ” results , they tot , saying that their model is now “ being extend to all other borough . ”
Their undertaking gives us a glimpse at the realistic middle ground between ignoring our infrastructure woefulness until our cities crumble and the doomsday scenario where we ’ll need to replace every inch of street over the next few ten . For now , the fire in London will keep smoldering — but in the hereafter , city engineers might know where and when to look out for the next problem .
