South Kitsap Fire and Rescue confirms the explosion happened at a residential structure. The building was leveled.
Officials told CBS affiliate KIRO-TV in Seattle the explosion occurred in a residence in Port Orchard shortly after 4 a.m.
It is not known if anyone was home during the blast.
Officials said the home was leveled by the blast, and the fire has been contained. The cause of the explosion is unclear.
An elementary school several hundreds yards away saw many of its windows shattered.
Several nearby residents told KIRO they initially thought it was an earthquake. One resident told KIRO that officers at Naval Base Kitsap in nearby Bremerton across the inlet from Port Orchard sent officers searching the base for the source until they realized what had happened.














Comment: Last August a huge gas explosion leveled a large section of a motel in Bremerton in Washington state.
There seems to have been an increase in the number of massive house explosions around the world in recent months, with investigators still attempting to determine the cause in many cases. Could a 'cosmic' source of ignition be responsible for some of these incidents?
