"We can all let out a cautious sigh of relief for now," Santaquin Fire and EMS said on Facebook early Sunday.
"A successful backburn operation helped protect the town overnight, and no primary structures were lost," Utah Fire Info said.
The power was also out in Eureka, and Utah Fire Info said it would be restored after safety issues are assessed.
Officials have not disclosed the fire's specific cause other than to say it was caused by humans. It's unclear how many homes are evacuated, but the latest census data from 2020 estimated between 662 and 828 people live there.
