SEATTLE (AP) — Utility crews have found three more natural gas leaks in the north Seattle neighborhood where a home exploded, injuring two residents in a two-alarm fire.
Puget Sound Energy spokeswoman Martha Monfried says the pipes have been dug up for repair.
More than two dozen utility employees are using sniffer equipment to sweep the area within five miles of Monday’s blast.
Harborview Medical Center said Tuesday that the woman injured in the fire remains in serious condition and her husband is in satisfactory condition.
Fire Department spokesman Kyle Moore says damage from the blast is estimated at $350,000.
Puget Sound Energy says the leaks were apparently caused by corrosion from electrical current after a tree knocked down a wire Sunday.
The utility has 750,000 natural gas customers in five counties.
