Fox13 Seattle is reporting that the explosion appears to have been caused by fireworks.

When the Seattle Fire Department (SFD) arrived, there was no active fire, but one person was seriously injured. The SPD announced later that the patient’s injuries were non-life threatening.

According to SPD Public Information Officer Judinna Gulpan, the explosion was caused by a man who was handling fireworks during the explosion.

“He did sustain a non-life-threatening injury to his hand,” said Gulpan. “Police arrived on scene and provided medical aid to him before Seattle Fire Department arrived. When they arrived, they continued medical assistance and later transported him to Harborview Medical Center for further medical evaluation.”
