Another JOLT!

These tremors keep coming even after the damage is done. (See links to local news photos and reports.) I just felt a notable jolt and a moderately loud "crack" like a close thunder clap - but no thunder! Then some low vibrations for a short time. Checked the US Geological Survey Website (now bookmarked!) and yes, another quake 3.6M. All this from my interior office in the windowless basement about 45 minutes ago. Now (approx. 2pm) still more low rumbling... I am starting not to like this!
