Puget Sound Energy crews worked through the night checking for more natural gas leaks in the north Seattle neighborhood where a home exploded Monday and injured two residents.
Spokesman Roger Thompson says crews walked and drove a 5-square mile area using sensitive equipment that can detect methane.
Thompson says the leak that set off the blast was caused by corrosion initiated when a tree knocked down a power line Sunday and electricity traveled into pipes in the ground.
Two residents burned in the blast and fire are at Harborview Medical Center – a woman in serious condition and a man in satisfactory condition.
They were identified in The Seattle Times as 50-year-old Hong Phung, a Crista Ministries dietitian, and 53-year-old David Ingham, a Seattle City Light employee.
