(CNN)A spate of California wildfires has destroyed an area larger than New York City and Boston -- combined. And with only a quarter of the colossal Thomas Fire contained, the end is a long way off.
Santa Ana winds literally have been adding fuel to the fires.
Here are the staggering numbers behind the blazes:
242,500 acres
That's the size of the Thomas Fire, the largest one ripping across Southern California. It started in Ventura County and is now moving across Santa Barbara County.
At 242,500 acres, the Thomas Fire is the fourth largest blaze in modern California history. It's torched an area larger than New York City.
Altogether, wildfires this month have destroyed nearly 270,000 acres in Southern California, officials have said.
$55.6 million
That's how much money had been spent as of Tuesday fighting the Thomas Fire, according to Ventura County. And the cost is sure to grow since the inferno was only 30% contained as of Thursday afternoon.
18,000 homes threatened
At least 18,000 homes are threatened by the Thomas Fire as of Tuesday, according to the California Department of Forestry and Fire Protection, known as Cal Fire.
1,147 structures destroyed
More than 1,100 structures had been wiped out by Thursday, Cal Fire reported. It wasn't clear how many were homes and how many were businesses.
Nearly 9,000 firefighters
More than 8,000 firefighters were tackling the Thomas Fire alone. Almost 9,000 remain on the line at all the fires.
The Nevada Department of Corrections and Nevada Division of Forestry, which run conservation camps, have sent six trained crews of minimum security inmates to help.
Thousands more firefighters -- including from Arizona, Colorado, Idaho, Oregon, Utah and Washington state -- have been involved in battling the other wildfires.
85,000 power outages
Santa Barbara County has suffered intermittent but widespread power outages due to the Thomas Fire. Southern California Edison said that outages and surges had left up to 85,000 customers without electricity.
95,000 evacuees
At least 95,000 residents have been evacuated in Southern California, Cal Fire said Tuesday.
$10 billion
This year has been the costliest for wildfires in US history. Damages have topped $10 billion -- and that was before the current fires began in Southern California.
