Earthquake?

...I was sitting comfortably this morning, perusing my newest Men's Health Magazine before getting my day going and I heard - more than felt - a soft rumble. It seemed to last for little more than 10 or 15 seconds. I slept through the larger quake of a few week's ago so I didn't even realize what it was at first and then, when I did start to think of it as an earthquake, I still doubted - - there was no "quaking"; no vibrations I could feel.

Does anyone think this is anything to be concerned about? The earth shaking under our feet? Isn't it interesting how we all just go about our normal lives in spite of the "earth-shaking changes" around us every day? See my blog TOMORROW for more thoughts on this topic...or, better yet, post your own comment!
