A Tiny Earthquake Reported in Kennewick Yesterday or Was it?

The Pacific Seismic network reported a magnitude 2.2 earthquake yesterday in Kennewick

The quake actually shook a desolate area in Finley and was so weak you probably didn't even feel it.

There is actually a debate on whether is was actually an earthquake or and explosion. Living through some pretty big earthquake in California over the years trust me a 2.2 is small beans!
