While this probably has jack-all to do with the earth ringing at times, I'd like some opinions about things like this

depth, negative two point nine kilometers. THATS ABOVE GROUND and central WA and a couple surrounding states keep having them. Sometimes USGS lists them as explosions. But if an explosion causes a ~2 on the richter scale … isn't that really big ?

I looked up "depth" just now, and there's a few definitions that "different networks" might use … but none should be a mile plus underground. I'm confused and startled because if stuff is blowing up that frequently, and it's nigh my own back yard, well. I think I should know if we're just all about blowing stuff up.
