Wonder what caused it?

Lucky it wasn't worse.

SEATTLE (KOMO) - Nine Seattle firefighters were injured in an apparent natural gas explosion that leveled at least three businesses in the Greenwood neighborhood early Wednesday morning.

The explosion happened in the area of the Greenwood Quick Stop Market at N. 85th Street and Greenwood Avenue N. just before 1:45 a.m.

Firefighters were sent to the building about 40 minutes earlier for a report of a natural gas leak. While they were investigating the source of the leak, the building exploded, according to Seattle Fire officials.

I was working at the computer, and at about 1:45 there was a huge explosion - shook the house pretty good. A few things fell off shelves. That whole building (3 businesses) is gone, several others damaged, windows broken out for about a block around. Most of the firefighters that were injured have been released from the hospital.

I turned on the scanner when I heard the explosion. I have NEVER heard a fire dispatcher sounding so shaken up.

The area for several blocks around is closed off to traffic now, and may be closed for several days. Buses are rerouted, but running close to schedule.

Mr. Gyros, Neptune Coffee, and Greenwood Quik-Stop do not exist anymore - the building is gone. Several other businesses adjacent are damaged, including a relatively new bicycle shop and a new restaurant that was still under construction. The brothers that own Mr. Gyros are amazingly great people - been in the neighborhood for many years.

I used to be friends with the owners, though we've drifted out of touch over the last few years.

I heard the explosion too, and I'm almost in Shoreline.

Glad you're ok!
